Summary on Grant Application Form |
Our objective is to develop nanobridge Josephson junction superconducting circuits (based on single flux quantum (SFQ)
design) for high bandwidth, low noise digital signal processing (DSP) of signals from single photon detector arrays (in
particular SSPD (superconducting single photon detector) arrays) and assess their suitability for commercialisation.
SSPD arrays have many applications; as a fast, high efficiency, low noise detector for quantum key distribution, as a
component in quantum computing and for enhanced quantum imaging. The major hurdle to commercialisation of SSPD
array systems is the lack of suitable readout electronics able to process a large number of signals without significant heat
loading of the detector cold stage. SFQ readout offers a low power solution, enabling multiple pixels in a marketable,
mechanically cooled system. Nanobridge SFQ circuits for SSPD array readout are a new, undemonstrated alternative to
conventional tunnel junction SFQ circuits, with the advantage of predominantly single layer fabrication, smaller device size
and potential for integration on the same chip as the SSPD array
