Backstory: Possible Cats

A Q&A with Michael Haiden, Quantum Shorts finalist

Read the story first: Possible Cats

 

Can you give a short introduction to yourself?

I’m 27 and I study philosophy and political science in Austria. In my studies, I’m very interested in questions of ethics and economic inequality.

 

Your story touches on ethical themes like how new technology should be used. What was your inspiration?

My biggest inspiration is the work of Amartya Sen. He defines poverty as an absence of choices and of freedom and I read Sen’s works while writing the story and made the connection with this new technology that creates endless possibilities but is actually restricted to a few people. I started to think: how would people without access react or how would they feel?

 

The protagonist in your story grapples with the inequality. Did you have an idea how things would progress beyond the end of your story?

Sooner or later, you would have to enact some sort of change so that people will have access to the technology. But the question is how. Would it be by peaceful means, or is it going to become more chaotic, maybe even violent? I wanted to leave this open and just bring out the character’s resentment. Maybe, unfortunately, he just has to live with that.

 

What makes you interested in quantum physics?

Its similarities with philosophy. To me, the whole idea of philosophy is mostly to try to demolish things we believe and think are true but actually cannot really justify. I think what quantum physics also does is question our centuries-old ideas about philosophy, time, space, and causality. I don’t have a deep understanding of quantum physics but it is fascinating that it questions almost everything.

 

What was your writing process like?

I had the initial idea when I read the prompt. I knew it had to have cats. I also really like this theory in philosophy of possible worlds by David Lewis – that was why the professor was called “Lewis” in this story. I knew I had these elements, but didn’t really find a way to tell a story. Then I thought about the ethical dimension and it just happened by itself. I had the idea when I was sitting in class. I went home and wrote the whole thing in one sitting, then I edited it for a few days.

I tried to think about it a bit like a philosophical ethics paper. In philosophy, we always try to write examples and thought experiments. What was different was focusing on how the characters feel – Aaron is very resentful, Cynthia admires Lewis – and how they think and interact. This was a fascinating dimension to explore.

 

What is your favourite science-inspired book?

I love the works of Kurt Vonnegut, especially how he turns scientific concepts into absurd consequences. In Cat’s Cradle for example, a scientist develops a way to turn all liquid water into solid. Another work is Timequake where the world is set back years in time but everybody remembers it. In these years, they have to do everything again. It touches on discussions of determinism and free will. 

 

What does being a Quantum Shorts finalist mean to you?

A lot. It is my first try at fiction writing. I never thought that I have an artistic side, so such a prize is a welcome surprise for me.

 

Is there anything else you would like to tell us about you or your story?

I think that it is very important philosophers and scientists to engage with fiction writing. I think science fiction has a lot of potential to rattle us in our beliefs with scenarios that seem very real.

Quantum Theories: A to Z

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.

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.

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 ...
Superposition

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

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.

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.

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.

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.

T is for ...
Time travel

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

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.

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.

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.

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!

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.

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.

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.

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.

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.

K is for ...
Key

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

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.

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.

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.

I is for ...
Information

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

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”.

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.

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.

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.

U is for ...
Universe

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

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.

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.

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.

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.

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!

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.

R is for ...
Randomness

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

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.

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.

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.

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.

G is for ...
Gluon

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

I is for ...
Interferometer

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

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.

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.

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.

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.

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.

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.

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.

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!

A is for ...
Act of observation

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

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.
