RECONFIGURABLE SUPERCONDUTING AND PHOTONIC TECHNOLOGIES OF THE FUTURE

Computing with light using integrated optics has seen huge progress over the last 3-4-years in multiple fields such as neuromorphic computing, quantum computing and on-chip data storage.

This has created a vast ecosystem that relies on high-speed reconfigurations of nanophotonic circuits (such as their use as synapses or routing applications) and ultrafast yet high-resolution, low-power photodetection.

Currently, it is impossible to combine all these functionalities into an integrated platform that fits onto a single chip.

In RESPITE, by utilizing our newly invented superconducting Joule switches as neurons, multi-level phase change memory elements as synaptic weights, and superconducting single-photon detector arrays as retina we will demonstrate a novel platform which combines vision and cognition on a single chip. This new platform will allow in-sensor neuromorphic computing with unprecedented performance levels.

The platform will have attoJoule switching power consumption, sub-nanosecond latency, and high compactness (3000 neurons and >100K synapses on
