3. The value obtained after a calculation or measurement
5. Instructions written for a computer to follow
6. The different possible conditions a quantum system can have
8. Another word for the probability that something will happen
9. A connection between qubits where their measurement results can be strongly linked
10. Lowering the temperature of quantum hardware to help qubits work correctly
15. A single particle of light
