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…
Millisecond charge-parity fluctuations and induced decoherence in a superconducting qubit
D. Ristè, C. C. Bultink, M. J. Tiggelman +3
Quasiparticle excitations adversely affect the performance of superconducting devices in a wide range of applications. They limit the sensitivity of photon detectors in astronomy,…
Feedback control of a solid-state qubit using high-fidelity projective measurement
D. Ristè, C. C. Bultink, K. W. Lehnert +1
We demonstrate feedback control of a superconducting transmon qubit using discrete, projective measurement and conditional coherent driving. Feedback realizes a fast and determinis…
Initialization by measurement of a two-qubit superconducting circuit
D. Ristè, J. G. van Leeuwen, H. -S. Ku +2
We demonstrate initialization by joint measurement of two transmon qubits in 3D circuit quantum electrodynamics. Homodyne detection of cavity transmission is enhanced by Josephson…
Single-spin magnetometry with multi-pulse sensing sequences
G. de Lange, D. Ristè, V. V. Dobrovitski +1
We experimentally demonstrate single-spin magnetometry with multi-pulse sensing sequences. The use of multi-pulse sequences can greatly increase the sensing time per measurement sh…
