Abstract
A non-reciprocal quantum device that comprises a first terminal and a second terminal, a transmission structure connected between the first and second terminals and configured to transmit microscopic particles in at least a partially phase-coherent manner from the first terminal to the second terminal and possibly from the second terminal to the first terminal, wherein a time-reversal symmetry of the transmission of the particles is broken with respect to at least a portion of the transmission structure; wherein the time-reversal symmetry is broken in such a way that the transmission structure comprises a higher transmission probability for particles moving in a first direction from the first terminal to the second terminal than in a second direction from the second terminal to the first terminal.
