Qadence a differentiable interface for digital and analog programs

Published in IEEE Software, 2025

In this work we present Qadence, a high-level programming interface for building complex digital and analog quantum programs. Digital-analog quantum computing (DAQC) is an alternative paradigm for universal quantum computation combining digital gates with global analog operations acting on a register of interacting qubits. Currently, no available open-source software is tailored to express, differentiate, and execute programs within the DAQC paradigm. Qadence addresses this shortfall by seamlessly allowing the user to combine digital and analog primitives. With a flexible interface and focus on native differentiability, Qadence aims to support research in variational algorithms in these hybrid computational models. Read more

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.

Software at the intersection of Quantum and HPC & heterogeneous quantum computing

Published:

At this years ISC I gave two talks, and also a “meet the experts” session at the booth of the Julich Supercomputing Center. IBM Quantum had a workshop where themselves and partners gave updates on the the state of quantum-centric supercomputing (QCSC). I gave a talk on “Software for heterogeneous quantum computing”, presenting our joint work on creating a joint software-stack for QCSC. Primarily the work on resource management, the associated code for spank plugins for quantum resources and jobs, and our Qiskit integration. Read more
