Universal Characterization of Quantum Vacuum Measurement Engines
Robert Czupryniak, Bibek Bhandari, Paolo Andrea Erdman +1
Quantum measurements can inject energy into quantum systems, enabling engines whose operation is powered entirely by measurements. We develop a general theory of quantum vacuum mea…
Tunable Superconducting Quantum Interference Device Coupler for Fluxonium Qubits
Abhishek Chakraborty, Bibek Bhandari, D. Dominic Briseño-Colunga +7
Tunable couplers enable high-fidelity two-qubit gates leveraging high on/off coupling ratios and reduced crosstalk within a single design. We investigate a galvanically connected d…
Dynamical Sweet and Sour Regions in Bichromatically Driven Floquet Qubits
D. Dominic Briseño-Colunga, Bibek Bhandari, Debmalya Das +6
Modern superconducting and semiconducting quantum hardware use external charge and microwave flux drives to both tune and operate devices. However, each external drive is susceptib…
Quantum Benchmarking of High-Fidelity Noise-Biased Operations on a Detuned-Kerr-Cat Qubit
Bingcheng Qing, Ahmed Hajr, Ke Wang +19
Ubiquitous noises in quantum systems remain a key obstacle to building quantum computers, necessitating the use of quantum error correction codes. Recently, error-correcting codes…
