'We submitted 1000 _____ to the QPU.' What is a shot in quantum computing?
A 'shot' is a single execution of a quantum circuit. Because quantum measurements are probabilistic, circuits are run many times (shots) to build up a statistical distribution of results.

What does QPU stand for?
QPU stands for Quantum Processing Unit — the quantum hardware chip that executes quantum circuits, analogous to a GPU in classical computing.

'Quantum volume' is a metric that measures:
Quantum Volume (QV) is IBM's holistic benchmark measuring the largest random circuit a quantum computer can successfully execute, capturing qubit count, connectivity, and error rates together.

What is the key difference between running a circuit on 'real hardware' vs. a 'simulator'?
Real quantum hardware has physical noise, decoherence, and gate errors. Simulators run on classical computers and are noiseless by default, making them useful for algorithm development but not for studying real hardware behavior.
