Abstract
An AQFP circuit comprises a Josephson junction having a respective plasma frequency, a clocking signal line, an inductive coupler between said clocking signal line and said Josephson junction, and a data signal line be-tween a data signal source and said Josephson junction. The AQFP circuit is configured to feed into said clocking signal line an oscillating clocking signal having a clocking signal frequency selected so that said plasma frequency is an integral multiple of said clocking signal frequency.

An Adiabatic Quantum-Flux-Parametron (AQFP) circuit, comprising:
- a Josephson junction or an array of Josephson junctions, said Josephson junction or each Josephson junction in said array having a respective plasma frequency,
- a clocking signal line,
- an inductive coupler between said clocking signal line and said Josephson junction, or an array of inductive couplers between said clocking signal line and each Josephson junction in said array respectively, and
- a data signal line between a data signal source and said Josephson junction or each Josephson junction in said array;
- wherein said AQFP circuit is configured to feed into said clocking signal line an oscillating clocking signal having a clocking signal frequency, said clocking signal frequency being selected so that said plasma frequency or each respective plasma frequency is an integral multiple of said clocking signal frequency.
A method for operating an Adiabatic Quantum-Flux-Parametron (AQFP) circuit, which AQFP circuit comprises:
- a Josephson junction or an array of Josephson junctions, said Josephson junction or each Josephson junction in said array having a respective plasma frequency,
- a clocking signal line,
- an inductive coupler between said clocking signal line and said Josephson junction, or an array of inductive couplers between said clocking signal line and each Josephson junction in said array respectively, and
- a data signal line between a data signal source and said Josephson junction or each Josephson junction in said array;
- wherein said method comprises feeding into said clocking signal line an oscillating clocking signal having a clocking signal frequency, and selecting said clocking signal frequency so that said plasma frequency or each respective plasma frequency is an integral multiple of said clocking signal frequency.
