Dynamics of Majorana tetron qubits under quasiparticle poisoning

Sauri Bhattacharyya, Bernard van Heck

We study the dissipative dynamics of a Majorana tetron qubit in the presence of extrinsic quasiparticle poisoning due to the coupling to external leads. From the Bloch-Redfield equ…

Operation of a high-frequency, phase-slip qubit

Cheeranjeev Purmessur, Kaicheung Chow, Bernard van Heck +1

Aluminum-based Josephson junctions are currently the main sources of nonlinearity for control and manipulation of superconducting qubits. A constriction-based junction provides an…

Tunneling of fluxons via a Josephson resonant level

T. Vakhtel, P. D. Kurilovich, M. Pita-Vidal +3

Fluxons in a superconducting loop can be coherently coupled by quantum phase slips occurring at a weak link such as a Josephson junction. If Cooper pair tunneling at the junction o…

Quantum phase slips in a resonant Josephson junction

Tereza Vakhtel, Bernard van Heck

We investigate the consequences of resonant tunneling of Cooper pairs on the quantum phase slips occurring in a Josephson junction. The amplitude for quantum tunneling under the Jo…

Microwave spectroscopy of interacting Andreev spins

J. J. Wesdorp, F. J. Matute-Caňadas, A. Vaartjes +13

Andreev bound states are fermionic states localized in weak links between superconductors which can be occupied with spinful quasiparticles. Microwave experiments using superconduc…

Magnetic cooling and vibration isolation of a sub-kHz mechanical resonator

Bernard van Heck, Tim Fuchs, Jaimy Plugge +2

We report recent progress towards the realization of a sub-mK, low-vibration environment at the bottom stage of a dry dilution refrigerator for use in mechanical tests of quantum m…
