Peculiarities of quantum physics such as superposition and entanglement offer unprecedented advantages in secure communication, computing, sensing and metrology. The fundamentals of quantum optics was first used to demonstrate how quantum properties of light can provide sensing and metrology capabilities beyond the standard quantum limit. Recent progress in the development of photonic sources and detectors (specifically photon number resolving detectors) propels research and development in efficient and scalable quantum photonic sensing devices. The photon number resolving detection technology helps to design detection schemes beyond the standard homodyne and single photon detection. This enables photon parity or weak-homodyne detection strategies that uses the best of both discrete variable and continuous variable photonic information processing to advance quantum sensing and metrology. To support sensing applications that attain a real-world advantage across both scientific metrics and business value (surpassing existing classical techniques), significant development of new features are required in photonnumber-resolving detectors. In particular, low speeds and low photon number resolution on events with large photon numbers have been a bottleneck in bringing such devices to real-world applications. In the Project, the team will push the boundaries of photon-number-resolution technology by increasing its repetition rate and number resolution capability. These developments will be combined with novel detection schemes to demonstrate quantum photonic sensing beyond the shot-noise limit.
