Abstract
Disclosed herein is a method of performing quantum channel estimation. The method is performed by a first device of a transmission device, and may include a first quantum state transmission step of transmitting a first quantum state ρ including an N-qubit sequence to a second device of a reception device through a quantum channel, a second quantum state information reception step of receiving information about a second quantum state Φ(ρ) received by the second device through the quantum channel from the second device, and a quantum channel estimation step of estimating the quantum channel based on the received information about the second quantum state Φ(ρ).
