Project description
Quantum computing has become a core branch of research in the field of quantum technology due to recent advances in nano-scale fabrication processes. Control and manipulation of single photons of microwave frequencies represent the key features of superconducting quantum bits, the most advanced implementation of a quantum computer to date. However, broadband single microwave photon detectors remain elusive. Here, we develop a novel microwave photon power metrology platform which incorporates a novel broadband microwave photodetector and a novel microwave source. This platform solves the availability issue of a broadband single microwave photodetector, and establishes itself as a metrological tool to calibrate microwave photon sources, both classical and non-classical, down to an unprecedented attowatts level. This project will ultimately lead to quantum supercomputers that will drive the next quantum revolution, fundamentally impacting the well-being and economy of our society.
