1. A method for generating a quantum contextual measurement from a quantum device capable of performing continuous time evolution, 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.
