Rapidly growing quantum technologies exploit the fundamental aspects of measurement in quantum mechanics. Here we experimentally demonstrate non-demolition projective measurement of a single nuclear spin associated with a nitrogen-vacancy (NV) center in diamond under ambient conditions. This enables the detection of quantum jumps and the quantum Zeno effect and will push spin-based measurement precision beyond the standard quantum limit.
