Abstract
We measure the photon arrival timing jitter of three superconducting Microwave Kinetic Inductance Detectors (MKIDs) within a large array of 20,440 pixels, spanning resonating frequencies from 4 to 8 GHz. We analyze arrival time distributions for photon number n = 1 and n = 2 events and find the distribution full-width at half-maximum ranging from 132 to 796 ns across the three detectors. In combination with nearly zero dark counts and multiplexed readout schemes, sub-microsecond jitter can be leveraged for high-time resolved astronomy, quantum, and bio-physics applications. The measured system jitter serves as an upper limit for MKIDs, with optimized performance likely reaching tens of nanoseconds. We discuss how to improve upon the detector and readout performance.
期刊介绍：
Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology.
In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics.
APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field.
Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
