Claim 12:
13. A hybrid quantum-classical computing system for generating a quantum contextual measurement from a quantum device capable of performing continuous time evolution, the hybrid quantum-classical computing system including:
the quantum device, comprising a plurality of qubits and a qubit controller that manipulates the plurality of qubits; and
a classical computer including at least one processor and at least one non-transitory computer-readable medium, the at least one non-transitory computer-readable medium having computer program instructions stored thereon, the computer program instructions being executable by the at least one processor to cause the classical computer to cooperate with the quantum device to perform a method, the method comprising:
(A) generating a first measurement result, the generating comprising:
(A) (1) initializing the quantum device to a first initial quantum state;
(A) (2) applying, on the quantum device, a first continuous time evolution to the initial quantum state to generate a first evolved state; and
(A) (3) measuring the first evolved state on the quantum device to generate the first measurement result;

(B) generating a second measurement result, the generating comprising:
(B) (1) initializing the quantum device to a second initial quantum state;
(B) (2) applying, on the quantum device, a second continuous time evolution to the second initial quantum state to generate a second evolved state which is at least approximately equal to the first evolved state;
(B) (3) applying, on the quantum device, a third continuous time evolution to the second evolved state to generate a third evolved state; and
(B) (4) measuring the third evolved state on the quantum device to generate the second measurement result; and

(C) combining the first measurement result and the second measurement result to generate the quantum contextual measurement.
