Boundary-induced Majorana coupling in a planar topological Josephson junction
Hyeongseop Kim, Sang-Jun Choi, H. -S. Sim +1
Understanding environmental effects in a topological Josephson junction is vital for identifying signatures of Majorana modes. We consider a planar Josephson junction formed on the…
Dynamical parity selection in superconducting weak links
Nico Ackermann, Alex Zazunov, Sunghun Park +2
Excess quasiparticles play a crucial role in superconducting quantum devices ranging from qubits to quantum sensors. In this work we analyze their dynamics for phase-biased finite-…
Signatures of interactions in the Andreev spectrum of nanowire Josephson junctions
F. J. Matute-Cañadas, C. Metzger, Sunghun Park +7
We performed microwave spectroscopy of an InAs nanowire between superconducting contacts implementing a finite-length, multi-channel Josephson weak link. Certain features in the sp…
Coherent coupling between vortex bound states and magnetic impurities in 2D layered superconductors
Sunghun Park, Vıctor Barrena, Samuel Mañas-Valero +9
Bound states in superconductors are expected to exhibit a spatially resolved electron-hole asymmetry which is the hallmark of their quantum nature. This asymmetry manifests as osci…
Circuit-QED with phase-biased Josephson weak links
C. Metzger, Sunghun Park, L. Tosi +6
By coupling a superconducting weak link to a microwave resonator, recent experiments probed the spectrum and achieved the quantum manipulation of Andreev states in various systems.…
From adiabatic to dispersive readout of quantum circuits
Sunghun Park, C. Metzger, L. Tosi +4
Spectral properties of a quantum circuit are efficiently read out by monitoring the resonance frequency shift it induces in a microwave resonator coupled to it. When the two system…
