Full characterization of measurement-induced transitions of a superconducting qubit

Thomas Connolly, Pavel D. Kurilovich, Vladislav D. Kurilovich +12

Repeated quantum non-demolition measurement is a cornerstone of quantum error correction protocols. In superconducting qubits, the speed of dispersive state readout can be enhanced…

Characterization of drive-induced unwanted state transitions in superconducting circuits

W. Dai, S. Hazra, D. K. Weiss +11

Microwave drives are essential for implementing control and readout operations in superconducting quantum circuits. However, increasing the drive strength eventually leads to unwan…

Lumped-element broadband SNAIL parametric amplifier with on-chip pump filter for multiplexed readout

V. R. Joshi, S. Hazra, A. Z. Ding +7

We present a SNAIL-based parametric amplifier that integrates a lumped-element impedance matching network for increased bandwidth and an on-chip pump-port filter for efficient pump…

High-frequency readout free from transmon multi-excitation resonances

Pavel D. Kurilovich, Thomas Connolly, Charlotte G. L. Bøttcher +12

Quantum computation will rely on quantum error correction to counteract decoherence. Successfully implementing an error correction protocol requires the fidelity of qubit operation…

Quantum Error Correction of Qudits Beyond Break-even

Benjamin L. Brock, Shraddha Singh, Alec Eickbusch +5

Hilbert space dimension is a key resource for quantum information processing. A large Hilbert space is not only an essential requirement for quantum error correction, but it can al…

Quantum Control of an Oscillator with a Kerr-cat Qubit

Andy Z. Ding, Benjamin L. Brock, Alec Eickbusch +10

Bosonic codes offer a hardware-efficient strategy for quantum error correction by redundantly encoding quantum information in the large Hilbert space of a harmonic oscillator. Howe…

Real-time quantum error correction beyond break-even

V. V. Sivak, A. Eickbusch, B. Royer +10

The ambition of harnessing the quantum for computation is at odds with the fundamental phenomenon of decoherence. The purpose of quantum error correction (QEC) is to counteract the…

Fast Universal Control of an Oscillator with Weak Dispersive Coupling to a Qubit

Alec Eickbusch, Volodymyr Sivak, Andy Z. Ding +7

A controlled evolution generated by nonlinear interactions is required to perform full manipulation of a quantum system, and such control is only coherent when the rate of nonlinea…
