An on-chip microwave source The active elements of superconducting quantum circuits are typically addressed and controlled using pulses of microwave radiation. The microwaves are usually generated externally and coupled into the circuitry, resulting in rather bulky systems. Cassidy et al. developed an on-chip source of microwaves by using a superconducting Josephson junction inserted in a high-quality microwave cavity. The integrated version should enhance the control capability for…

It is demonstrated that semiconducting channels etched from a wafer-scale two-dimensional electron gas (2DEG) are a suitable platform for building a scalable gatemon-based quantum computer and measured qubit coherence times up to ~2 μs, limited by dielectric loss in the 2DEG substrate.

Injection locking and synchronization in Josephson photonics devices

Injection locking can stabilize a source of radiation, leading to an efficient suppression of noise-induced spectral broadening and therefore, to a narrow spectrum. The technique is well established
