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,…
Selective darkening of degenerate transitions demonstrated with two superconducting quantum bits
P. C. de Groot, J. Lisenfeld, R. N. Schouten +4
Controlled manipulation of quantum states is central to studying natural and artificial quantum systems. If a quantum system consists of interacting sub-units, the nature of the co…
Low-crosstalk bifurcation detectors for coupled flux qubits
P. C. de Groot, A. F. van Loo, J. Lisenfeld +4
We present experimental results on the crosstalk between two AC-operated dispersive bifurcation detectors, implemented in a circuit for high-fidelity readout of two strongly couple…
QND measurement of a superconducting qubit in the weakly projective regime
T. Picot, R. Schouten, C. J. P. M. Harmans +1
Quantum state detectors based on switching of hysteretic Josephson junctions biased close to their critical current are simple to use but have strong back-action. We show that the…
Nondestructive readout for a superconducting flux qubit
A. Lupascu, C. J. M. Verwijs, R. N. Schouten +2
We present a new readout method for a superconducting flux qubit, based on the measurement of the Josephson inductance of a superconducting quantum interference device that is indu…
