Abstract: This work presents a novel micromachined, seamless sapphire–silicon hybrid evanescent-mode cavity architecture incorporating selectively engineered coupling channels and flux-tunable external coupling via a SQUID. The proposed design enables two simulated operating states within a single device: an ultra–high Q memory configuration and a high-speed readout configuration with intrinsic Purcell filtering, which is expected to […]

Abstract: Over the past decade, Rydberg atom electric field sensors have been under investigation as potential alternatives or complements to conventional antenna-based receivers for select applications in RF communications, remote sensing, and precision metrology. To understand the potential utility of these devices for various use cases, it is crucial to develop models that accurately predict […]

Abstract: Engineering quantum circuits that use minimal resource requirements is essential for suppressing noise-induced errors and enhancing the performance of quantum processors. Here, we propose minimal-complexity hardware constructions of Clifford circuits for implementing new two-qubit Clifford gates, effectively expanding the available Clifford circuit library. The circuits are realized through engineered coherent phonon-mediated interactions between two […]

Single Hole Spin Qubit Optimization in SOI Quantum Dots Via kk⋅pp Simulations and Perturbative Analysis

Abstract: Hole spin qubits in silicon nanostructures offer fast, all-electrical control through electric-dipole spin resonance (EDSR), yet their performance strongly depends on device geometry. In this work, optimization criteria of Rabi frequency of single-hole spin qubits in silicon-on-insulator (SOI) quantum dots are identified by combining electrostatic and kk⋅pp simulations with a perturbative model of the […]
