Erasure-Flip Logic Gate for Momentum Computing

Abstract

Researchers at the University of California, Davis have developed a method and device performing simultaneous flip and merge operations to improve logical operation performance in high-efficiency superconducting circuits.

Full Description

This technology introduces a method and apparatus that initialize circuits to an initial logical state and perform simultaneous flip and merge operations on sets of logical states to map to a final logical state, enabling more efficient and accurate logical operations. The design leverages conventional Josephson junction circuit elements and uses novel control methods thereon to synchronize these operations, leading to improved computation speed, greatly reduced energy requirements, and reliability beyond traditional quantum flux parametron approaches. The operation relies only on Josephson junction nonlinearity, which is a classical physics phenomenon and not a quantum-mechanical phenomenon.
