Controllable freezing of the nuclear spin bath in a single-atom spin qubit
The quantum coherence and gate fidelity of electron spin qubits in semiconductors are often limited by nuclear spin fluctuations. Enrichment of spin-zero isotopes in silicon markedly improves the dephasing time [Formula: see text] , which, unexpectedly, can extend two orders of magnitude beyond theo...
