We demonstrate heterogeneous III/V-on-Si resonator modulators with sub-10 mV and GHz modulation at 4 K. This record performance is enabled by strong EO effects of III/V quantum-wells at 4 K, and with minimal free-carrier freezing of III/V semiconduct

A well-known component of RF systems is the circulator, a three-port device that allows signals to flow in one direction while inhibiting propagation in the reverse direction. Circulators play an important role in protecting sensitive RF devices from

We investigate the accessibility and projected low-noise performance of single soliton Kerr frequency combs in silicon nitride microresonators enabled by operating at cryogenic temperatures as low as 7 K. The resulting two orders of magnitude reducti

The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is responsible for all dephasing of the quantum state. In practice, imperfec
