Bob skipped out onto the empty flat roof, tangoed three or four steps, and yipped at the blue-veined ice planet hung in the night sky.  Then he saw a man leaning on the roof’s waist-high ledge, staring down at the street twenty stories below.  The guy appeared when Bob looked his way.

Coming from his lover--the scent of her jasmine perfume still in his mustache--Bob felt relaxed . . . and magnanimous.  He pointed at the night sky, the luminous white planet, the winking stars.  “Beautiful, huh?”

The guy at the wall snorted and turned.  Though still in his late twenties, he was already balding and had a wobbly bit of belly under a black T-shirt that showed off his snake tattoos--serpents that would ripple when he flexed his biceps and forearms.

Bob looked out over the hardpan moonscape and sighed.  He sauntered across the flat roof to the edge, gravel crackling under his loafers.  “You sure you want to do this?”

“What’s it to you?”

“Nothing, except you’re spoiling my elation.”

Again the guy snorted.  “You think my night is all jazz and whiskey?”

“Doesn’t mean you have to spoil it for others.”

“Oh, sorry.  We suicides should be more polite.”

“Look, if you jump, I’ll have to bother with the police.  And you’ll definitely ruin the night for someone down there.”

When Bob pointed down at the street, the silver top of an ion bus appeared, and a woman carrying a violin case blipped into view as she glided along a rolling sidewalk.

“You might collide with someone,” Bob said, “or even deflect a vehicle.”

Sudden, intense fear flashed through Bob.  His sight swirled, and he had to widen his stance to keep his balance.  The scent of jasmine perfume laid a bitter taste on his dry tongue.  Just as quickly as it came, the fear evaporated.

Had this been a flash-forward like with Alice?  Three days before meeting her, Bob had woken up with the feeling that the entire universe loved him.  He had taken a joyful morning walk, smiling at everyone, and people had smiled back.  Every sound had pleased him:  the gurgle of a baby, the begging chirp of a town sparrow.

The guy shrugged.  “Guess I am spoiling things for you.  Sorry.”  He put out his hand.  “I’m called Max.”

Bob figured that if Max had wanted to make the jump, he already would have done so.  He shook Max’s hand.  “Bob.”

Instead of letting go of his hand, Max jerked Bob toward the wall.  Bob’s left knee smacked against the concrete ledge; the pain made him suck in his breath.  Before he could regain his balance, Max shoved him over the ledge but didn’t release his grip.

Bob clung to Max’s hand.  The toes of his leather loafers scrabbled against the high-rise’s concrete surface.

Max laughed.  “You’re about to spoil someone’s night.”

“Why me?  Please, I’ll do anything.”

“Why my wife, Alice?”

Max opened his hand and watched Bob so he wouldn’t disappear.  Bob dropped away from the roof and immediately bounced against the rolling sidewalk below without falling between them.

Max smiled, knowing that Alice, entangled as she was with Bob, had bounced against the floor with bone-splinter force in the apartment six floors below him.

Quantum Theories

G is for ... Gluon

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

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”.

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.

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.

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.

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.

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 ... 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.

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.

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.

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!

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.

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.

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!

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.

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.

R is for ... Radioactivity

The atoms of a radioactive substance break apart, emitting particles. It is impossible to predict when the next particle will be emitted as it happens at random. All we can do is give the probability that any particular atom will have decayed by a given time.

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.

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 ... Superposition

Quantum objects can exist in two or more states at once: an electron in superposition, for example, can simultaneously move clockwise and anticlockwise around a ring-shaped conductor.

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.

K is for ... Kaon

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

U is for ... Universe

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

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.

A is for ... Act of observation

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

I is for ... Information

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

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.

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 ... 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.

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.

R is for ... Randomness

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

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.

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 ... 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.

I is for ... Interferometer

Some of the strangest characteristics of quantum theory can be demonstrated by firing a photon into an interferometer: the device’s output is a pattern that can only be explained by the photon passing simultaneously through two widely-separated slits.

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.

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 ... 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.

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.

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.

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.

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.

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.

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.

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.
