20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
Distinct Lifetimes for and Loop Measurements in a Majorana Tetron Device
Morteza Aghaee, Zulfi Alam, Rikke Andersen +164
We present a hardware realization and measurements of a tetron qubit device in a superconductor-semiconductor heterostructure. The device architecture contains two parallel superco…
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…
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…
Optimizing the pump coupling for a three-wave mixing Josephson parametric amplifier
Wei Dai, Gangqiang Liu, Vidul Joshi +4
Josephson element-based parametric amplifiers (JPAs) typically require rf pump power that is several orders of magnitude stronger than the maximum signal power they can handle. The…
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…
