Quantum Physics

1. A particle of light; carries energy but has no mass.
3. The act of observing a quantum system, which forces it to choose a specific state.
4. A set of instructions for solving a problem using quantum computers.
8. The basic unit of quantum information, like a bit in classical computing, but it can be both 0 and 1 at the same time (superposition).
13. A strong connection between quantum particles, so that the state of one instantly affects the other, even at a distance.
16. When a quantum particle exists in multiple states at once until it is measured.
18. A computer that uses qubits to perform calculations based on quantum mechanics.
20. Using quantum principles (like entanglement) to create unbreakable codes.

2. States that you cannot know both the exact position and exact speed (momentum) of a particle at the same time.
5. Regular computing using bits (0s and 1s) and traditional electronic devices.
6. A branch of physics that deals with the behavior of very small particles like atoms and electrons.
7. A mathematical way to describe where a particle is likely to be.
9. A basic operation that changes the state of qubits.
10. The idea that quantum computers can solve some problems much faster than regular computers.
11. The smallest possible amount of a physical quantity, like energy.
12. A tiny particle with a negative charge that orbits the nucleus of an atom.
14. The science of keeping information secret and secure.
15. The description of a particle’s properties (like position, energy, spin).
17. A method of secure communication that uses quantum mechanics to share encryption keys safely.
19. The concept that particles like electrons and photons can behave like both waves and particles.
