LonΔar's Laboratory for Nanoscale Optics engineers diamond and lithium-niobate nanophotonic devices β including silicon-vacancy (SiV) color-center spin-photon interfaces, entangled quantum memories, and remote entanglement-assisted phase-sensing protocols that beat the standard measurement limit β alongside quantum optomechanical control of single spins via engineered acoustic resonators, directly extending the NV/SiV-diamond quantum-sensing lineage toward chip-integrated, networked quantum-enhanced sensing.
Sipahigil leads the Berkeley Quantum Devices Group, which integrates diamond and silicon-carbide color-center spin qubits with nanophotonic cavities to build quantum networks and solid-state quantum sensors, spanning superconducting circuits to color-center-based quantum memories. The group is actively recruiting postdocs.
