Single-spin qubit magnetic spectroscopy of two-dimensional superconductivity
A single-spin qubit placed near the surface of a conductor acquires an additional contribution to its 1/T1 relaxation rate due to magnetic noise created by electric current fluctuations in the material. We analyze this technique as a wireless probe of superconductivity in atomically thin two-dimensional materials. At temperatures T≲Tc, the …
