Hidehiro Yonezawa's Quantum Optics Lab

at UNSW Canberra, Australia

Our research interests lie in quantum optics and quantum information. We have been working on quantum-enhanced protocols and measurements such as quantum teleportation, quantum-enhanced phase estimation, quantum parameter estimation, generation of non-Gaussian quantum states/gates, large-scale quantum entanglement, quantum tomography, quantum control and coherent-feedback control.
