All-nitride superconducting qubits based on atomic layer deposition
Danqing Wang, Yufeng Wu, Naomi Pieczulewski +6
The development of large-scale quantum processors benefits from superconducting qubits that can operate at elevated temperatures and be fabricated with scalable, foundry-compatible…
A transmon qubit realized by exploiting the superconductor-insulator transition
C. G. L. Bøttcher, E. Önder, T. Connolly +8
Superconducting qubits are among the most promising platforms for realizing practical quantum computers. One requirement to create a quantum processor is nonlinearity, which in sup…
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…
Recovery dynamics of a gap-engineered transmon after a quasiparticle burst
Heekun Nho, Thomas Connolly, Pavel D. Kurilovich +4
Ionizing radiation impacts create bursts of quasiparticle density in superconducting qubits. These bursts temporarily degrade qubit coherence which can be detrimental for quantum e…
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…
Coexistence of nonequilibrium density and equilibrium energy distribution of quasiparticles in a superconducting qubit
Thomas Connolly, Pavel D. Kurilovich, Spencer Diamond +5
The density of quasiparticles typically observed in superconducting qubits exceeds the value expected in equilibrium by many orders of magnitude. Can this out-of-equilibrium quasip…
Coupling Two Spin Qubits with a High-Impedance Resonator
S. P. Harvey, C. G. L. Bøttcher, L. A. Orona +3
Fast, high-fidelity single and two-qubit gates are essential to building a viable quantum information processor, but achieving both in the same system has proved challenging for sp…
