Classification: CPC G | IPC G

Claim 0:
1. A method comprising:
performing a measurement process on a state of a quantum circuit, the measurement process resulting in an amplitude corresponding to the state of the quantum circuit and further corresponding to a first location in an object database;
executing, using a quantum processor and a second memory, a search operation comprising a first quantum amplification operation, a result of the first quantum amplification operation on the amplitude removing a target object basis state from the uniform superposition representation of the state of the quantum circuit;
executing, using a classical processor and a first memory, a verification operation, the verification operation comparing a target object with a first object, the first object stored in the first location; and
executing, using the quantum processor and the second memory, responsive to the verification operation determining that the target object is different from the first object, a second quantum amplification operation, wherein a sum of the first quantum amplification operation and the second quantum amplification operation is less than a threshold value determined from a set of objects in the object database.
