Reversible computation with flux solitons

摘要

A reversible superconducting circuit includes a plurality of Josephson transmission lines. A first line is configured to transmit a control fluxon when a first input is active. A second line is configured to transmit a target fluxon to one of a third and a fourth line. The circuit is configured to transmit the fluxons at substantially the same time. The second line is configured to transmit the target fluxon to the third line, due to an interaction between the control fluxon and the target fluxon, only if the control fluxon is transmitted at substantially the same time as the target fluxon. The second line is configured to transmit the target fluxon to the fourth line, due to following an adiabatic trajectory, only if no control fluxon is transmitted at substantially the same time as the target fluxon.
