Quantum computation based on Reciprocal Quantum logic

Abstract

This paper gives a newfangled dimension to superconducting logic which is the successor of CMOS logic and other superconducting quantum logic. Reciprocal Quantum logic (RQL) is proposed to achieve the less memory capability. RQL is a modified version of Rapid Single Flux Quantum (RSFQ). We designed and analyzed different RQL logic like half adder, full adder, counter, and Carry Save Adder (CSA) and we achieved an increase in clock speed compared to RSFQ logic by 20%. The designs are made of AndOr and AnotB gate operation and analyzed using WRSPICE software.
