Precise timekee** is critical to metrology, forming the basis by which standards of time,
length, and fundamental constants are determined. Stable clocks are particularly valuable in …

Spin defects in silicon carbide have the advantage of exceptional electron spin coherence
combined with a near-infrared spin-photon interface, all in a material amenable to modern …

Nuclear spins in the solid state are both a cause of decoherence and a valuable resource for
spin qubits. In this work, we demonstrate control of isolated 29Si nuclear spins in silicon …

We experimentally demonstrate the protection of a room-temperature hybrid spin register
against environmental decoherence by performing repeated quantum error correction whilst …
