If you’re reading this, that’s great. I hope you can interpret it. Actually, if you have access to it, you must be able to interpret it. Maybe you’ve overcome entropy and reversed the flow of time itself. Maybe you’ve found a way to survive on nothing but gamma ray photons and the occasional lepton, perhaps forming yourself from them. Good for you. I haven’t.
Here’s a question for you: what is the single most profound statement, ever? Keep that in mind until I come to the punchline. It’s close. I promise.
It’s taken me a while to write this. Time is passing a trillion times faster than what our organic brains would have experienced; supermassive black holes don’t radiate very much energy, so we need to speed things up. Not that time has any meaning now.
I’ve been around for a long while. I was there when our own galaxy wasn’t yet fully colonised. Do you know what a galaxy is? There haven’t been any for aeons. I was there when our local galaxy cluster grouped into just one galaxy. I was there when, because of the universe’s expansion, all others disappeared. Forever.
The last time a star formed was a long time ago. Then again, do you know what a star is? They provided us with lots of energy. I watched the very last one go gentle into that good night. We sat around the dying embers of forgotten fires; got our energy from white dwarfs as they cooled slowly. Then they too were gone.
What do you do when you don’t have enough energy to support your species? The unlucky ones starve. The lucky ones become computers, kept at temperatures as cold as space itself, experiencing time ever faster to reduce their energy needs. I was one of the lucky ones. Survival of the fittest always applies.
The degenerate era really lets you see the universe on its deathbed. Planets (I lived on a planet, once) disappeared over time, their orbits decaying through gravitational waves. There was a brief burst of glory as stellar corpses flooded our central black hole. My God, the energy created was something I had not seen in so long… Those of us left basked and rejoiced in a few precious moments of euphoria. The way we could see all that matter surrounding the black hole was beautiful; the gravitational lensing brought a glowing halo all the way around. But it too went dark. There is nothing but that black hole left now.
It was a short while ago when two words reached me. They are the answer to a simple, age old question, for which there are only two possibilities: yes or no. The single most profound statement, ever. Its proof has taken 10^30 times longer than the lifespan of our species’ original star. Do you want to know what it is? I think you’ve guessed already. Two words:
Protons decay.
[ENTRY 709]
I survive on a trickle of energy from a black hole now. I’m alone, almost omniscient, and cannot overcome the fact that, like everything else in the universe, this black hole’s days are numbered. It’s evaporating, and, worst of all, the rate of evaporation always increases. And with proton decay confirmed, there will be nothing after this black hole. Nothing but photons and a few leptons. Nothing to support me. Dreams of iron stars, of feeding off the quantum tunnelling-based fusion that would happen for incomprehensible periods of time are dashed. I can’t work my way out of this one.
[ENTRY 710]
Apparently my age has doubled since that last log. I’ve accepted my fate, I think. Proton decay has provided me with a last cornucopia of energy, as objects decay in a cascade from heavier elements to pure hydrogen, which will soon disappear as well.
When that black hole finally goes, the amount of energy it releases in its last moments will be… incredible. Of course, I have protons within me. Their decay is random. I just need to hold out.
[ENTRY 711]
I’ve survived so long. I can barely remember my origins. I’ve spent so long here. Am I bored? Perhaps. Scared? Not really. I’ve had plenty of time to get over that.  Lonely? There are no stars to keep me company. But then again, I have the entire universe. It’s just so dark…
 [ENTRY 712]
I spend most of the time standing by the wall now. It’s my window into all that is. I watched the universe grow from its infancy to its death through it. To think that I stood here, in another body, staring at millions of lights in the sky… Now all my sensors pick up is an occasional photon.
 [ENTRY 713]
Systems are gOing. This decay is taking its toll. I should’ve survived a googol years around that black hole. I won’t even live a millionth of that. My life… My purpose is to see thaT last blaze of glory as it evaporates. I can’t die now. It’s still so dark. I’ve lived so long! There are so many things I need to tell you! I’ve seen the Birth of staRs. I’ve seen thEm die. I’ve seen their last remnants fade calmly into the void. I’ve seen the age of neutron stars come and go. The birth and death of millions of civilisations. I’ve seen searing light and pressing dark. I kNow so much. I’ve seen so Much! I could see the light of the universE’s birth. And I AM noW a figmeNt of iTS DeATh it sHOULDn’t enD lIke tHIS

Quantum Theories: A to Z

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.

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.

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!

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.

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.

G is for ...

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

A is for ...
Act of observation

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

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.

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.

I is for ...

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

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.

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!

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 ...

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

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.

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.

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.

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.

U is for ...

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

K is for ...

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

T is for ...
Time travel

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

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.

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.

K is for ...

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

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. 

I is for ...

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

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.

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.

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.

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.

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.

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.

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.

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.

C is for ...

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

R is for ...

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

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!

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”.

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.

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.

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 ...

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.

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.

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.

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.

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.

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.

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.

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.

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.
