Everything about QMA

Quantum Merlin Arthur

QMA, as an abbreviation for Quantum Merlin Arthur, refers to a complexity class in computational complexity theory. It is the set of all formal languages that satisfy the following properties:If a string is in the language, then there is a polynomial-size quantum proof that convinces a polynomial-time quantum verifier of this fact with high probability. If a string is not in the language, every polynomial-size quantum state is rejected by the verifier with high probability. Wikipedia →
