Parity lifetime of bound states in a proximitized semiconductor nanowire
Bound states in semiconductor–superconductor hybrids are shown to have parity lifetimes of over 10 milliseconds, suggesting that they could provide a platform for topological quantum computing. Quasiparticle excitations can compromise the performance of superconducting devices, causing high-frequenc...

but remain relatively unexplored in semiconductor–superconductor structures, which are now being intensely pursued in the context of topological superconductivity. To this end, we use a system comprising a gate-confined semiconductor nanowire with an epitaxially grown superconductor layer, yielding an isolated, proximitized nanowire segment. We identify bound states in the semiconductor by means of bias spectroscopy, determine the characteristic temperatures and magnetic fields for quasiparticle excitations, and extract a parity lifetime (poisoning time) of the bound state in the semiconductor exceeding 10 ms. |
