Abstract
En 中文
Quantum technologies offer profound advances in communication security, sensing and computing. The underpinning hardware must be engineered to generate, manipulate and detect quantum phenomena with exceptional performance while being mass-manufacturable for real-world applications. A leading approach is chip-scale quantum photonics. The continuous-variable regime for quantum optics has been exploited in a number of technologies, including the detection of gravitational waves, by operating below the standard quantum limit of the light’s shot noise. The availability of room-temperature, deterministic sources and high-efficiency detectors suitable for continuous-variable state generation and measurement is a compelling motivation for this particular paradigm. This Review focuses on efforts to integrate sources and detectors of continuous-variable light states into chip-scale photonic integrated circuits. In this Review the authors cover the latest efforts to integrate sources and detectors of continuous-variable quantum light states into chip-scale photonic integrated circuits.
