1. A computer implemented method comprising:
storing, in a quantum memory, multiple copies of a quantum state, comprising, for each copy of the quantum state, i) probing, by an initialized quantum sensor, a target system to obtain an evolved quantum state of the quantum sensor, ii) transducing the evolved quantum state of the quantum sensor into a quantum state of a quantum buffer, iii) logically encoding the quantum state of the quantum buffer into a quantum error correcting code, and iv) moving the logically encoded quantum state of the quantum buffer into the quantum memory;
loading the multiple copies of the quantum state in the quantum memory into a quantum computer;
processing, by the quantum computer, the multiple copies of the quantum state to obtain a purified quantum state; and
measuring the purified quantum state to determine properties of the target system.
