We experimentally demonstrate the first inductive readout of optically hyperpolarized phosphorus-31 donor nuclear spins in an isotopically enriched silicon-28 crystal. The concentration of phosphorus donors in the crystal was 1.5×10(15)  cm(-3), 3 orders of magnitude lower than has previously been detected via direct inductive detection. The signal-to-noise ratio measured in a single free induction decay from a 1  cm(3) sample (≈10(15) spins) was 113. By transferring the sample to an X-band ESR…

Thermodynamics of Mesoscopic Quantum Systems: from a single qubit to light harvesting complexes
Over the past few years, the exploration of mesoscopic quantum systems progressed drastically with experiments one could not imagine twenty years ago. New measurements, such as the detection of
Mesoscopic spin systems as quantum entanglers
We quantify the resources required for entangling two uncoupled spin qubits through an intermediate mesoscopic spin system (MSS) by indirect joint measurement. Indirect joint measurement benefits
