** QUANTUM SHORTS 2023/2024: SHORTLISTED

>> Read an interview with the author

 

Prologue

Dear judges, for Quantum Shorts’ ultimate run,

I thought a submission in verse might be fun.

My piece is a story in every key sense,

With a narrative arc and a bit of suspense,

A host of known characters, conflict galore,

Irreverent waggery, drama and more.

Though lacking in reason, it’s riddled with rhyme,

And short enough not to take much of your time.

In closing, I’d like to thank you and your staff;

I hope that my yarn gives you all a good laugh.

 

 

Quantum cake à la Solvay

The history of physics contains ’til this day

A little-known secret surrounding Solvay.

Aside from the talks among Einstein’s old pals,

Were parallel sessions arranged by the gals.

They beat God at dice and exchanged idle chat,

And nursed Erwin Schrödinger’s traumatized cat.

They made snide remarks about Marie Curie,

And bad-mouthed the men over pastries and tea:

Their gripes over prizes and coveted chairs,

Romantic entanglements, steamy affairs,

Herr Pauli’s exclusion from trivia night,

And Planck’s constant rants about quanta of light,

That Erwin was dishy but Niels was a bore,

And Werner would sleep through his lectures and snore.

The girls’ greatest secret undoubtedly, though,

Was Madame De Broglie’s new quantum gâteau.

It’s said those who tried it could not get enough;

It wasn’t like Thomson’s old plum-pudding stuff.

So here we explain the procedures to make

A version of Madame’s original cake.

(The optimal order is still in dispute,

But mixing and baking for sure don’t commute.)

First preheat the oven to one-eighty C

(Or four-fifty K, give or take a degree).

Beat butter and sugar with integer spin,

Then fold all the other ingredients in.

Don’t measure them, though, or you’ll alter their state;

Just guess the amounts and then leave it to fate.

(You might get a cake that’s too dry or too greasy,

But nobody said this was going to be easy!)

Now transfer the mix to a suitable pan,

And bake thirty minutes (or less with the fan).

The pan must be deep and have sides that are stout

To prevent the raw batter from tunneling out.

The cake should turn golden and rise as it cooks –

But don’t take a peek to assess how it looks!

Just wait for the specified time to elapse,

Or you’ll trigger the wave function’s fatal collapse.

By quantum mechanics and these simple rules

You can eat the cake hot and still wait ’til it cools.

This feat marks the theory’s preeminent coup:

The proof you can have your cake and eat it too.

Quantum Theories: A to Z

T is for ...
Teleportation

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.

M is for ...
Multiverse

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.

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.

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.

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.

X is for ...
X-ray

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.

R is for ...
Randomness

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

L is for ...
Light

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.

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 ...
Computing

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.

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.

A is for ...
Atom

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

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.

E is for ...
Entanglement

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.

K is for ...
Kaon

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

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.

E is for ...
Ethics

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 ...
Information

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

C is for ...
Cryptography

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

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.

S is for ...
Superposition

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

G is for ...
Gluon

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

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.

R is for ...
Reality

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!

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!

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”.

I is for ...
Interferometer

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

D is for ...
Decoherence

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

T is for ...
Time

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 ...
Wavefunction

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.

Q is for ...
Qubit

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.

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.

P is for ...
Probability

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.

T is for ...
Tunnelling

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 ...
Sensors

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

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.

D is for ...
Dice

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.

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.

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.

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 ...
Gravity

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.

M is for ...
Maths

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

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.

K is for ...
Key

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

U is for ...
Universe

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

A is for ...
Act of observation

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

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.

C is for ...
Clocks

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.

N is for ...
Nonlocality

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.
