Coherent Control of a Single Silicon-29 Nuclear Spin Qubit

Abstract

Magnetic fluctuations caused by the nuclear spins of a host crystal are often the leading source of decoherence for many types of solid-state spin qubit. In group-IV materials, the spin-bearing nuclei are sufficiently rare that it is possible to identify and control individual host nuclear spins. This work presents the first experimental detection and manipulation of a single ${}^{29}$Si nuclear spin. The quantum non-demolition (QND) single-shot readout of the spin is demonstrated, and a Hahn echo measurement reveals a coherence time of $T_2=6.3(7)$ ms - in excellent agreement with bulk experiments. Atomistic modeling combined with extracted experimental parameters provides possible lattice sites for the ${}^{29}$Si atom under investigation. These results demonstrate that single ${}^{29}$Si nuclear spins could serve as a valuable resource in a silicon spin-based quantum computer.
