We'll email you occasional competition updates and tell you who wins.

- 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 ” more from our A-Z of

the quantum world

- 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. ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- 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. ” more from our A-Z of

the quantum world

- 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! ” more from our A-Z of

the quantum world

- R is for Randomness
- “ Unpredictability lies at the heart of quantum mechanics. It bothered Einstein, but it also bothers the Dalai Lama ” more from our A-Z of

the quantum world

- 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 ” more from our A-Z of

the quantum world

- O is for Objective reality
- “ Neils 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. ” more from our A-Z of
