A Q&A with Colm O’Shea, Quantum Shorts finalist
Can you give a short introduction to yourself?
I teach essaying to college students, and the essay—ideally—is a sandpit of ideas to play in. Conceptual play (exploring ideas just for the fun of it) is my favourite thing to do.
How did you come up with the idea for your story?
The quantum theorist Paul Dirac said: “A place is nothing: not even a space, unless at its heart—a figure stands.” I love that strange quote. I think he’s saying that a reference point is always needed: there’s no high without low, no left without right, and no “nothing” without “something” (and vice-versa). I’ve been carrying that idea around for a long time, but it didn’t occur to me to use it as a seed for a short story until I saw the Quantum Shorts fiction invite. Since I’m also intrigued by the possibility of sentient AI, I wanted to imagine what it would be like for an AI consciousness to realize that she isn’t just the “figure” in the story, but rather she is the interrelation of the space and the figure. She discovers she is the intersection of all possible computable worlds.
One final note on the idea source: I stole the fly image from an Emily Dickinson poem “I Heard a Fly Buzz—When I Died.” It’s a poem about an indeterminate state between life and death.
Your story makes interesting use of perspectives with a little twist at the end. Was it tricky to plan or write?
No one knows where ideas come from, but my media diet plays a big role in what emerges on the page. For instance, before I wrote “A World Apart,” I had been doing math/logic puzzles. One of the puzzles struck me as especially tricky, because the perspectives of the characters in the scenario—what they know and don’t know—played a part in the solution. So although I didn’t know exactly how to translate that experience into a short story, I knew that I wanted a radical perspective shift to occur by the end somehow.
What makes you interested in quantum physics?
Oddly, perhaps, I came to the mysteries of quantum physics when I was writing a book on James Joyce’s Finnegans Wake and the Buddhist concept of non-duality. Murray Gell-Mann, the CalTech scientist, was a fan of the Wake because it’s basically a vast nest of puzzles. In fact, Gell-Mann coined the word “quark” from a line in the book: “Three quarks for Muster Mark!”
I know there are a lot of amazing applications of quantum theory yet to be discovered, but I’m most excited about how it might help us understand what consciousness is—about what thisness is.
What is your favourite science-inspired book?
I’m going to cheat and give three answers: one book that helped me teach my kids; one that makes me reflect on strange questions; and a final one that made me dream when I was a child. The first is a wondrous introduction to geometry by my friend the mathematician Paul Lockhart called Measurement. This connects to my second choice, Shape, by Jordan Ellenberg, which asks odd questions like “How many holes does a straw have?” (He gives more than one possible answer.) Finally, the first science fiction book I read was Isaac Asimov’s Fantastic Voyage. That made me want to dream up my own fantastic voyages.
What does being a Quantum Shorts finalist mean to you?
When I was a kid, I felt that school was a sorting mechanism, and the “arty” people went in one group, and the “math-science” people went in another. They were segregated tribes, almost. I’m not denying that kids have natural inclinations, but to reinforce that art/science division squanders an opportunity for children—and by extension adults—to explore the whole geography of the brain! I would say to both tribes that the best treasure tends to be buried in the place you don’t feel you belong, or even feel afraid of. For me, for a long time, that was math and physics. Being picked as a finalist makes me want to reach out to people who think “I’m not a math/physics person.” Science and literature are everyone’s birthright. If you shut yourself off from some of the most exciting ideas humanity has ever played with, you are depriving yourself.
Some people believe this changes everything in the quantum world, even bringing things into existence.
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.
This is the basic building block of matter that creates the world of chemical elements – although it is made up of more fundamental particles.
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!
At extremely low temperatures, quantum rules mean that atoms can come together and behave as if they are one giant super-atom.
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.
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.
People have been hiding information in messages for millennia, but the quantum world provides a whole new way to do it.
Unless it is carefully isolated, a quantum system will “leak” information into its surroundings. This can destroy delicate states such as superposition and entanglement.
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.
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.
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.
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.
These elementary particles hold together the quarks that lie at the heart of matter.
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.
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.
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.
Many researchers working in quantum theory believe that information is the most fundamental building block of reality.
Some of the strangest characteristics of quantum theory can be demonstrated by firing a photon into an interferometer
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.
These are particles that carry a quantum property called strangeness. Some fundamental particles have the property known as charm!
Quantum Key Distribution (QKD) is a way to create secure cryptographic keys, allowing for more secure communication.
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.
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.
Quantum physics is the study of nature at the very small. Mathematics is one language used to formalise or describe quantum phenomena.
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.
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.
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.
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.
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.
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.
Quantum states, which represent the state of affairs of a quantum system, change by a different set of rules than classical states.
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.
Unpredictability lies at the heart of quantum mechanics. It bothered Einstein, but it also bothers the Dalai Lama.
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!
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.
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.
Researchers are harnessing the intricacies of quantum mechanics to develop powerful quantum sensors. These sensors could open up a wide range of applications.
The feature of a quantum system whereby it exists in several separate quantum states at the same time.
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.
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.
Is time travel really possible? This article looks at what relativity and quantum mechanics has to say.
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.
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.
To many researchers, the universe behaves like a gigantic quantum computer that is busy processing all the information it contains.
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.
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.
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.
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.
In 1801, Thomas Young proved light was a wave, and overthrew Newton’s idea that light was a “corpuscle”.
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.
