Spectroscopy of spin-split Andreev levels in a quantum dot with superconducting leads
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +9
We use a hybrid superconductor-semiconductor transmon device to perform spectroscopy of a quantum dot Josephson junction tuned to be in a spin-1/2 ground state with an unpaired qua…
Direct manipulation of a superconducting spin qubit strongly coupled to a transmon qubit
Marta Pita-Vidal, Arno Bargerbos, Rok Žitko +9
Spin qubits in semiconductors are currently one of the most promising architectures for quantum computing. However, they face challenges in realizing multi-qubit interactions over…
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…
Mitigation of quasiparticle loss in superconducting qubits by phonon scattering
Arno Bargerbos, Lukas Johannes Splitthoff, Marta Pita-Vidal +6
Quantum error correction will be an essential ingredient in realizing fault-tolerant quantum computing. However, most correction schemes rely on the assumption that errors are suff…
Microwave-activated gates between a fluxonium and a transmon qubit
Alessandro Ciani, Boris M. Varbanov, Nicolas Jolly +2
We propose and analyze two types of microwave-activated gates between a fluxonium and a transmon qubit, namely a cross-resonance (CR) and a CPHASE gate. The large frequency differe…
Singlet-doublet transitions of a quantum dot Josephson junction detected in a transmon circuit
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +10
We realize a hybrid superconductor-semiconductor transmon device in which the Josephson effect is controlled by a gate-defined quantum dot in an InAs/Al nanowire. Microwave spectro…
