Single-electron spin resonance detection by microwave photon counting
Quantronics group at CEA Saclay has recently developed a new method for EPR spectroscopy with single spin sensitivity. Their results have just been published in Nature.
Deterministic Free-Propagating Photonic Qubits with Negative Wigner Functions
In optical quantum technologies, many tasks require highly non-classical pulses of light where the field statistics, in contrast with classical probablities, take negative values. So far, such pulses could only be prepared using probabilistic measurement-based approaches. The Quantum Photonics Team of Collège de France prepared them in a fully deterministic way…
