Abstract
Provided is a device for initializing a quantum state. The device includes: a control register that receives a quantum state of a control qubit S and outputs a computation result thereon; at least one auxiliary register that receives a quantum state of a target qubit A1 . . . An (n is a natural number of 1 or larger) in a one-to-one manner; a collective CNOT gate unit including a plurality of CNOT gates respectively connected to the control registers and connected to the at least one auxiliary register in a one-to-one manner; at least one detector connected to the at least one auxiliary register in a one-to-one manner and configured to measure a computation result of the collective CNOT gate unit; and a quantum state output unit ρ(n) that applies a noise removal protocol based on the measurement result of the detector to output an initialized quantum state from which noise has been removed.
