"This transformation you underwent, was it painful in any way?" Dr. Fenton made notes on his clipboard as he spoke.
"There was no transformation," Brinks said. "Why can't you understand that?" Captain Brinks had expected a hero's welcome. Instead, all he got were stares and even a few screams. As the first person to cross interstellar space, the last thing he expected was to be treated like a zoo animal, caged in a quarantined hospital room, interrogated by a psychoanalyst through a glass wall.
"Then how do you explain your appearance?"
"I'm not the one who's different," Brinks said. "You are."
"But I don't feel any different. How do you explain that?"
Brinks took a step toward the thick pane of glass separating him from Dr. Fenton, and Dr. Fenton took a frightened step back. "Look," Brinks said, "something big has happened. Bigger than you can imagine. The universe--the  universe I knew--is gone."
Dr. Fenton shook his head in confusion. "I'm sorry, come again?"
"Are you familiar with how the Quantum Probability Wave Attenuator works?"
"Doesn’t it use wormholes to propel your ship, the Astral Star?"
"Not wormholes," Brinks corrected. "It quantum-tunnels the ship from one location to another by attenuating every probability wave but the one that will get you where you want to go."
Dr. Fenton looked up from his clipboard. "Okay, how is a tunnel different from a wormhole?"
Brinks was glad to finally have the opportunity to explain his predicament. "Wormholes bend space and require godlike amounts of energy. Quantum tunneling, on the other hand, is where a particle simply disappears and instantly reappears somewhere else. It happens spontaneously all the time at the subatomic level. That clipboard you're holding? There is a non-zero probability that it could suddenly disappear and reappear on the other side of the universe. But the probability is so low, it may as well be zero. That's where the Quantum Probability Wave Attenuator comes in. It's like rigging the quantum lottery so every subatomic particle in an object gets lucky and wins the tunneling lottery at exactly the same time."
"And this is how your ship works?"
"Exactly. Only what wasn't known at the time is that quantum luck is conserved. For something the size of my ship to tunnel across the galaxy, you'd have to wait about ten-to-the-power-of-fifty years before it's likely to have happened spontaneously. So by rigging the quantum lottery so my ship could tunnel to Proxima Centauri, we robbed the universe of ten-to-the-power-of-fifty years’ worth of quantum luck, diminishing the level of subatomic tunneling going on in the universe."
"And how do you know this?" Dr. Fenton put his pen to his clipboard as if expecting an especially delusional account.
"Four hours after I arrived at Proxima Centauri, the star went out. Like blowing out a candle. Know how far away I was? Four light-hours away. That star went out the instant I tunneled. It couldn't have been a coincidence."
"Why would tunneling to Proxima Centauri make the star go out?"
"Because stars depend on nuclear fusion, which requires a certain level of tunneling activity."
"But wait…" Dr. Fenton put down his clipboard. "So all tunneling stopped throughout the universe because of your ship? Because of you? Throughout the universe?"
"Not completely. Probably just enough to make the stars go out. Solid-state electronics, even our brains require some level of tunneling activity to function, so I knew tunneling hadn't completely halted."
"But our sun didn't go out when you went to Proxima Centauri."
Brinks leaned forward and lowered his voice. "Oh, but it did. You just don't remember."
"Uh-huh," Dr. Fenton picked up his clipboard. "What happened next?"
"I knew the star going out was only temporary," Brinks said. "Without the internal pressure of fusion to hold the star's outer shell at bay, the massive shell would collapse until there was sufficient pressure to restart nuclear fusion at the diminished tunneling rate, causing the star to explode in a nova. When I figured out what was happening, I abandoned my data-gathering and set the attenuator to take me home. Back to Earth."
"And what did you find when you got here?"
"I found a dead, collapsing sun, about to blow and obliterate Earth."
Dr. Fenton looked at Brinks over his glasses. "But you saved Earth, didn't you?"
"Damn straight I did." Brinks knew he was being baited, but he didn't care. "And not just Earth, but the whole universe."
"Right. Sorry. How, exactly?"
Brinks spoke clearly, knowing his next words would either vindicate or condemn him. "I decided to go for broke. I inverted the field so the attenuator, instead of tunneling the ship, would tunnel everything outside the ship. I set the controls to the level required to stop all tunneling, everywhere, throughout the universe. Then I pressed the button."
"And this accomplished what?"
"Don't you get it?" Brinks said. "I tunneled the entire universe! This universe is only two days old!"
"Then why do I remember what happened last week, or last year? Why is there a compelling history that goes farther back than two days?"
"I know. It’s a lot to think about. It's a new state of existence," Brinks said, "not a new Big Bang. A Boltzmann universe, if you will, with an established, causal progression of events."
Dr. Fenton pushed his glasses up and gazed at Brinks as if he had reached a new understanding. "But something went wrong, didn't it?"
"You could say that," Brinks said. "Some things were different. Minor things."
"Ah. Like the horns on your head?"
"Yes. But like I said, I'm not the one who's changed. You're the ones who've changed. Before I pushed that button, everyone had horns on their head."
"Right." Dr. Fenton picked up his clipboard and flipped to a new page. Without looking at Brinks, he clicked his pen. "Now, about your tail…"

Quantum Theories: A to Z

T is for ...

The arrow of time is “irreversible”—time goes forward. On microscopic quantum scales, this seems less certain. A recent experiment shows that the forward pointing of the arrow of time remains a fundamental rule for quantum measurements.

R is for ...

Since the predictions of quantum theory have been right in every experiment ever done, many researchers think it is the best guide we have to the nature of reality. Unfortunately, that still leaves room for plenty of ideas about what reality really is!

P is for ...
Planck's Constant

This is one of the universal constants of nature, and relates the energy of a single quantum of radiation to its frequency. It is central to quantum theory and appears in many important formulae, including the Schrödinger Equation.

C is for ...

The rules of the quantum world mean that we can process information much faster than is possible using the computers we use now. This column from Quanta Magazine ​delves into the fundamental physics behind quantum computing.

M is for ...
Many Worlds Theory

Some researchers think the best way to explain the strange characteristics of the quantum world is to allow that each quantum event creates a new universe.

P is for ...

Quantum mechanics is a probabilistic theory: it does not give definite answers, but only the probability that an experiment will come up with a particular answer. This was the source of Einstein’s objection that God “does not play dice” with the universe.

E is for ...

When two quantum objects interact, the information they contain becomes shared. This can result in a kind of link between them, where an action performed on one will affect the outcome of an action performed on the other. This “entanglement” applies even if the two particles are half a universe apart.

C is for ...

People have been hiding information in messages for millennia, but the quantum world provides a whole new way to do it.

L is for ...

We used to believe light was a wave, then we discovered it had the properties of a particle that we call a photon. Now we know it, like all elementary quantum objects, is both a wave and a particle!

H is for ...
Hawking Radiation

In 1975, Stephen Hawking showed that the principles of quantum mechanics would mean that a black hole emits a slow stream of particles and would eventually evaporate.

S is for ...
Schrödinger Equation

This is the central equation of quantum theory, and describes how any quantum system will behave, and how its observable qualities are likely to manifest in an experiment.

T is for ...
Time travel

Is time travel really possible? This article looks at what relativity and quantum mechanics has to say.

B is for ...
Bell's Theorem

In 1964, John Bell came up with a way of testing whether quantum theory was a true reflection of reality. In 1982, the results came in – and the world has never been the same since!

L is for ...
Large Hadron Collider (LHC)

At CERN in Geneva, Switzerland, this machine is smashing apart particles in order to discover their constituent parts and the quantum laws that govern their behaviour.

Q is for ...

One quantum bit of information is known as a qubit (pronounced Q-bit). The ability of quantum particles to exist in many different states at once means a single quantum object can represent multiple qubits at once, opening up the possibility of extremely fast information processing.

T is for ...

Quantum tricks allow a particle to be transported from one location to another without passing through the intervening space – or that’s how it appears. The reality is that the process is more like faxing, where the information held by one particle is written onto a distant particle.

G is for ...

Our best theory of gravity no longer belongs to Isaac Newton. It’s Einstein’s General Theory of Relativity. There’s just one problem: it is incompatible with quantum theory. The effort to tie the two together provides the greatest challenge to physics in the 21st century.

K is for ...

These are particles that carry a quantum property called strangeness. Some fundamental particles have the property known as charm!

C is for ...

The most precise clocks we have are atomic clocks which are powered by quantum mechanics. Besides keeping time, they can also let your smartphone know where you are.

W is for ...

The mathematics of quantum theory associates each quantum object with a wavefunction that appears in the Schrödinger equation and gives the probability of finding it in any given state.

I is for ...

Many researchers working in quantum theory believe that information is the most fundamental building block of reality.

G is for ...

These elementary particles hold together the quarks that lie at the heart of matter.

J is for ...
Josephson Junction

This is a narrow constriction in a ring of superconductor. Current can only move around the ring because of quantum laws; the apparatus provides a neat way to investigate the properties of quantum mechanics and is a technology to build qubits for quantum computers.

Y is for ...
Young's Double Slit Experiment

In 1801, Thomas Young proved light was a wave, and overthrew Newton’s idea that light was a “corpuscle”.

M is for ...

Quantum physics is the study of nature at the very small. Mathematics is one language used to formalise or describe quantum phenomena.

D is for ...

Unless it is carefully isolated, a quantum system will “leak” information into its surroundings. This can destroy delicate states such as superposition and entanglement.

S is for ...
Schrödinger’s Cat

A hypothetical experiment in which a cat kept in a closed box can be alive and dead at the same time – as long as nobody lifts the lid to take a look.

N is for ...

When two quantum particles are entangled, it can also be said they are “nonlocal”: their physical proximity does not affect the way their quantum states are linked.

V is for ...
Virtual particles

Quantum theory’s uncertainty principle says that since not even empty space can have zero energy, the universe is fizzing with particle-antiparticle pairs that pop in and out of existence. These “virtual” particles are the source of Hawking radiation.

O is for ...
Objective reality

Niels Bohr, one of the founding fathers of quantum physics, said there is no such thing as objective reality. All we can talk about, he said, is the results of measurements we make.

T is for ...

This happens when quantum objects “borrow” energy in order to bypass an obstacle such as a gap in an electrical circuit. It is possible thanks to the uncertainty principle, and enables quantum particles to do things other particles can’t.

F is for ...
Free Will

Ideas at the heart of quantum theory, to do with randomness and the character of the molecules that make up the physical matter of our brains, lead some researchers to suggest humans can’t have free will.

R is for ...

Unpredictability lies at the heart of quantum mechanics. It bothered Einstein, but it also bothers the Dalai Lama.

S is for ...

The feature of a quantum system whereby it exists in several separate quantum states at the same time.

E is for ...

As the world makes more advances in quantum science and technologies, it is time to think about how it will impact lives and how society should respond. This mini-documentary by the Quantum Daily is a good starting point to think about these ethical issues. 


K is for ...

Quantum Key Distribution (QKD) is a way to create secure cryptographic keys, allowing for more secure communication.

X is for ...

In 1923 Arthur Compton shone X-rays onto a block of graphite and found that they bounced off with their energy reduced exactly as would be expected if they were composed of particles colliding with electrons in the graphite. This was the first indication of radiation’s particle-like nature.

D is for ...

Albert Einstein decided quantum theory couldn’t be right because its reliance on probability means everything is a result of chance. “God doesn’t play dice with the world,” he said.

B is for ...
Bose-Einstein Condensate (BEC)

At extremely low temperatures, quantum rules mean that atoms can come together and behave as if they are one giant super-atom.

A is for ...

This is the basic building block of matter that creates the world of chemical elements – although it is made up of more fundamental particles.

A is for ...
Act of observation

Some people believe this changes everything in the quantum world, even bringing things into existence.

U is for ...

To many researchers, the universe behaves like a gigantic quantum computer that is busy processing all the information it contains.

A is for ...
Alice and Bob

In quantum experiments, these are the names traditionally given to the people transmitting and receiving information. In quantum cryptography, an eavesdropper called Eve tries to intercept the information.

Q is for ...
Quantum biology

A new and growing field that explores whether many biological processes depend on uniquely quantum processes to work. Under particular scrutiny at the moment are photosynthesis, smell and the navigation of migratory birds.

S is for ...

Researchers are harnessing the intricacies of quantum mechanics to develop powerful quantum sensors. These sensors could open up a wide range of applications.

U is for ...
Uncertainty Principle

One of the most famous ideas in science, this declares that it is impossible to know all the physical attributes of a quantum particle or system simultaneously.

I is for ...

Some of the strangest characteristics of quantum theory can be demonstrated by firing a photon into an interferometer

Q is for ...
Quantum States

Quantum states, which represent the state of affairs of a quantum system, change by a different set of rules than classical states.

M is for ...

Our most successful theories of cosmology suggest that our universe is one of many universes that bubble off from one another. It’s not clear whether it will ever be possible to detect these other universes.

W is for ...
Wave-particle duality

It is possible to describe an atom, an electron, or a photon as either a wave or a particle. In reality, they are both: a wave and a particle.

H is for ...
Hidden Variables

One school of thought says that the strangeness of quantum theory can be put down to a lack of information; if we could find the “hidden variables” the mysteries would all go away.

Z is for ...
Zero-point energy

Even at absolute zero, the lowest temperature possible, nothing has zero energy. In these conditions, particles and fields are in their lowest energy state, with an energy proportional to Planck’s constant.
