• The group's overarching research theme involves exploring the nonclassical light generation for quantum sensing, quantum key distribution, and cavity optomechanics for nonreciprocal devices. We employ coherent control and open quantum systems to investigate nonclassical light generation from quantum dot systems and nonreciprocal phenomena in cavity optomechanics. The group is currently focusing on generating entangled photon pairs via spontaneous parametric down-conversion in a nonlinear crystal for quantum sensing applications.
