Method for increasing quantum entanglement quantum repeating method and quantum repeater using thereof

摘要

The present invention relates to a method for increasing quantum entanglement, a quantum heavily method using the same, and a quantum repeater, and a method for increasing quantum entanglement according to the present invention includes receiving two input signals of a quantum state, A Pauli channel for the background noise of the form is calculated and mixed with noise different from the background noise using the calculated Fourier channel and the quantized entanglement is extracted from the mixed background noise and the input signal.
