Magnetic field induced superconductivity is a fascinating quantum phenomenon, whose origin is yet to be fully understood. The recently discovered spin triplet superconductor, UTe2, exhibits two such superconducting phases, with the second one reentering in the magnetic field of 45 T and persisting up to 65 T. More surprisingly, in order to induce this superconducting phase, the magnetic field has to be applied in a special angle range, not along any high symmetry crystalline direction. The teams of QMC faculty Nick Butch and Johnpierre Paglione have investigated the evolution of this exotic superconducting phase under pressure, shedding more light on the mechanism of reentrant superconductivity This work has been posted on arXiv.

The team of QMC faculty member Vlad Manucharyan have reported a record coherence time for their fluxonium qubit, achieving an average single-qubit gate fidelity above 0.9999, surpassing that of any other solid-state quantum system. Combined with recent demonstrations of two-qubit gates on fluxoniums, this result paves the way for the next generation of quantum processors. See preprint at https://arxiv.org/abs/2103.08578
