Nonvolatile Cryogenic Phase Slip Memory with Single-Shot Readout
arXiv:2505.02090 · doi:10.1103/wrvj-5737
Abstract
The demand for cryogenic memory components is driven by the need for ultra-fast, low-power, and highly reliable computing systems. Phase slip-based devices promise to fulfill all these requirements, with potential applications in both classical and quantum information processing. However, previous implementations have faced challenges due to inefficient writing and readout schemes. In this work, we address these limitations with a simple device design and measurement techniques inspired by circuit quantum electrodynamics. We present a memory element that stores information in the winding of a high-kinetic inductance superconducting loop, inductively coupled to a coplanar waveguide resonator. Using single-shot measurements, we achieve a readout fidelity of 99.698\% with an active measurement time of just 25 ns.
