High Kinetic Inductance Superconducting Nanowire Resonators for Circuit QED in a Magnetic Field
N. Samkharadze, A. Bruno, P. Scarlino +4
We present superconducting microwave-frequency resonators based on NbTiN nanowires. The small cross section of the nanowires minimizes vortex generation, making the resonators resi…
Realization of microwave quantum circuits using hybrid superconducting-semiconducting nanowire Josephson elements
G. de Lange, B. van Heck, A. Bruno +6
We report the realization of quantum microwave circuits using hybrid superconductor-semiconductor Josephson elements comprised of InAs nanowires contacted by NbTiN. Capacitively-sh…
Mitigating information leakage in a crowded spectrum of weakly anharmonic qubits
V. Vesterinen, O. -P. Saira, A. Bruno +1
A challenge for scaling up quantum processors using frequency-crowded, weakly anharmonic qubits is to drive individual qubits without causing leakage into non-computational levels…
Entanglement genesis by ancilla-based parity measurement in 2D circuit QED
O. -P. Saira, J. P. Groen, J. Cramer +3
We present an indirect two-qubit parity meter in planar circuit quantum electrodynamics, realized by discrete interaction with an ancilla and a subsequent projective ancilla measur…
Reversing quantum trajectories with analog feedback
G. de Lange, D. Ristè, M. J. Tiggelman +6
We demonstrate the active suppression of transmon qubit dephasing induced by dispersive measurement, using parametric amplification and analog feedback. By real-time processing of…
Deterministic entanglement of superconducting qubits by parity measurement and feedback
D. Ristè, M. Dukalski, C. A. Watson +6
The stochastic evolution of quantum systems during measurement is arguably the most enigmatic feature of quantum mechanics. Measuring a quantum system typically steers it towards a…
