Readout-Induced Leakage in Superconducting Circuits with Nonlinear Couplings
Sumeru Hazra, Wei Dai, Daniel K. Weiss +3
In superconducting circuits, drive-induced unwanted transitions limit the readout power, thereby constraining readout speed and fidelity. When such transitions excite the qubit int…
Probing the memory of a superconducting qubit environment
Nicolas Gosling, Denis Bénâtre, Nicolas Zapata +8
Achieving fault tolerance with superconducting quantum processors requires qubits to operate within the regime of threshold theorems based on the Born-Markov approximation. This ap…
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…
Long-range connectivity in a superconducting quantum processor using a ring resonator
Sumeru Hazra, Anirban Bhattacharjee, Madhavi Chand +4
Qubit coherence and gate fidelity are typically considered the two most important metrics for characterizing a quantum processor. An equally important metric is inter-qubit connect…
Engineering Cross Resonance Interaction in Multi-modal Quantum Circuits
Sumeru Hazra, Kishor V. Salunkhe, Anirban Bhattacharjee +5
Existing scalable superconducting quantum processors have only nearest-neighbor coupling. This leads to reduced circuit depth, requiring large series of gates to perform an arbitra…
