Flux Pumped Kerr-Free Parametric Amplifier
Kagan Yanik, Irwin Huang, Bibek Bhandari +7
We propose a flux-pumped superconducting parametric amplifier based on symmetrically threaded superconducting quantum interference devices (SQUIDs) that achieves a Kerr-free operat…
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…
Making the Virtual Real: Measurement-Powered Tunneling Engines
Rafael Sánchez, Alok Nath Singh, Andrew N. Jordan +1
Quantum tunneling allows electrons to be transferred between two regions separated by an energetically forbidden barrier. Performing a position measurement that finds a particle in…
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…
Capturing an Electron in the Virtual State
Alok Nath Singh, Bibek Bhandari, Rafael Sánchez +1
We address a foundational question in quantum mechanics: Can a particle be directly found in a classically forbidden virtual state? We instantiate this conceptual question by inves…
