Same-spin Andreev reflections in the quantum Hall regime: the role of loss
Chun-Chia Chen, Jordan T. McCourt, John Chiles +7
The interfaces of superconductors and topological materials hold promise for realizing exotic states and excitations. An important example is provided by the chiral Andreev edge st…
Probing Cooper pair momentum by quasiparticle steering with planar Josephson junctions
Isidora Araya Day, Anton R. Akhmerov, Antonio R. L. Manesco
The Cooper pair momentum in a superconductor is associated with a phase gradient of the superconducting order parameter. In general, this momentum is small compared to the Fermi mo…
Coherent control of spinmons
Johanne Bratland Tjernshaugen, Florinda Viñas Boström, Jeroen Danon +3
The protection of superconducting qubits from certain noise sources often comes at the cost of increased sensitivity to other decoherence channels. Here, we explore a route to avoi…
Loopless multiterminal quantum circuits at odd parity
Antonio Manesco, Anton Akhmerov, Valla Fatemi
We theoretically investigate loopless multiterminal hybrid superconducting devices at odd fermion parity with time-reversal symmetry. We find that the energy-phase relationship has…
Strain engineering of Andreev spin qubits in Germanium
Vittorio Coppini, Patrick Del Vecchio, Antonio L. R. Manesco +4
Planar germanium heterostructures are promising hosts for hybrid quantum devices due to their compatibility with superconductors, low material disorder, and relaxed fabrication con…
Pareto-optimality of Majoranas in hybrid platforms
Juan Daniel Torres Luna, Sebastian Miles, A. Mert Bozkurt +4
To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in p…
