Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Sercan Deve, Gary A. Steele, , | Summary: Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Alberto Bordin, Guanzhong Wang, Chun-Xiao Liu, Sebastiaan L. D. ten Haaf, Grzegorz P. Mazur | Summary: A short superconducting segment can couple attached quantum dots via elastic co-tunneling (ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host Majorana bound states provided that the ratio […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Haining Pan, F. Setiawan, Michael Wimmer, Jay D. Sau | Summary: In a recent breakthrough experiment (arXiv:2206.08045), Majorana zero modes have been observed in tunnel spectroscopy for a minimal Kitaev chain constructed from coupled quantum dots. However, as Ising anyons, Majoranas’ most fundamental property of […]

Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: G. P. Mazur, N. van Loo, D. van Driel, J. -Y. Wang, G. Badawy | Summary: Superconducting diodes are a recently-discovered quantum analogueue of classical diodes. The superconducting diode effect relies on the breaking of both time-reversal and inversion symmetry. As a result, the critical current […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Matthijs H. J. de Jong, Andrea Cupertino, Dongil Shin, Simon Gröblacher, Farbod Alijani | Summary: Mechanical resonators that possess coupled modes with harmonic frequency relations have recently sparked interest due to their suitability for controllable energy transfer and non-Hermitian dynamics. Here, we show coupling between high Q-factor […]
Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: N. van Loo, G. P. Mazur, T. Dvir, G. Wang, R. C. Dekker | Summary: The proximity effect in semiconductor-superconductor nanowires is expected to generate an induced gap in the semiconductor. The magnitude of this induced gap, together with the semiconductor properties like the spin-orbit coupling […]
