Paper Published in Nature Nanotechnology!
Prof. Zhang and Berkeley team's work in Nature Nanotechnology demonstrates a three-qubit quantum register in silicon photonics. We integrated T centers into photonic waveguides and achieved entanglement between nuclear spins with long coherence times, showing promise for quantum communication networks. 🎉

Paper Published in PRX Quantum!
Prof. Zhang and Berkeley team's work in PRX Quantum explores the stability of T centers in silicon photonic cavities. We show that their emission remains stable for milliseconds in the dark, but laser light itself drives spectral diffusion. These insights point to strategies for producing indistinguishable photons, a key step toward scalable quantum networks. 🎉
