Abstract
In one aspect, there is provided a method for transmitting a two-qubit state. The method includes: propagating the two-qubit state onto a transmission waveguide, wherein the propagating includes distributing the two-qubit state about a certain phase; and transmitting the two-qubit state through the transmission waveguide using a pump pulse having the certain phase, wherein the pump pulse is provided in a manner so that the transmission waveguide functions as an optical phase sensitive amplifier (OPSA).
