The MQO group investigates fundamental physics and develops quantum applications with mesoscopic-sized quantum states of light, all underpinned by enabling technology. Mesoscopic quantum optical states comprise 10s, 100s and 1000s of nonclassically-distributed photons. From a fundamental perspective, they can be used to explore quantum physics at energy scales that are visible to the human eye, thereby exposing some of the highly counter-intuitive phenomena of quantum mechanics at a human scale. In addition, this scale is crucial for demonstrating a genuine quantum enhancement over classical schemes in many areas including metrology, computation and communication.
In this context, the research of the MQO group can be divided into three areas: developing enabling technology for mesoscopic quantum optics, fundamental physics with mesoscopic quantum states, and applications of mesoscopic quantum optics.
