Pulse level simulation of neutral atom QPUs

Published:

I presented on behalf of Pasqals emulation team our work on tensor network simulations of pulse level programming of neutral atom QPUs as well as our work on differentiable simulators for digital-analog algorithms. The work presented centred around our whitepaper for the cloud-based tensor network emulator (EMU-TN)[https://arxiv.org/abs/2302.05253] and the emulators built for the then not yet released (Qadence)[https://github.com/pasqal-io/qadence] digital-analog quantum programming interface.
