Higher Josephson harmonics in a tunable double-junction transmon qubit
Ksenia Shagalov, David Feldstein-Bofill, Leo Uhre Jakobsen +11
Tunable Josephson harmonics open new avenues for qubit design. We demonstrate a superconducting circuit element consisting of a tunnel junction in series with a SQUID loop, yieldin…
Non-Hermitian skin effect and electronic nonlocal transport
Carlos Payá, Oliver Solow, Elsa Prada +2
Open quantum systems governed by non-Hermitian effective Hamiltonians exhibit unique phenomena, such as the non-Hermitian skin effect, where eigenstates localize at system boundari…
Directional conductance of Andreev crystals in hybrid Josephson junction arrays
Anders Enevold Dahl, Andrea Maiani, Max Geier +2
Andreev bound states are coherent electron-hole superpositions that form in a normal metal through repeated Andreev reflection at a superconducting interface. When the length of a…
Signatures of exceptional points in multiterminal superconductor-normal metal junctions
Oliver Solow, Karsten Flensberg
We study a non-Hermitian, multiterminal superconducting-normal system in order to identify experimental signatures of exceptional points. We focus on a minimal setting with a singl…
Phase-controlled minimal Kitaev chain in multiterminal Josephson junctions
Samuel D. Escribano, Anders Enevold Dahl, Karsten Flensberg +1
We propose a nanodevice based on multi-terminal Josephson junctions for the creation and detection of poor man's Majorana (PMM) modes. The device consists of a double three-termina…
