I’m happy to announce the results a collaboration with Adrian Franco Rubio, Alatz Alvarez Ahedo and Mikel Sanz, “Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation”, arxiv.org/abs/2505.03642. The title is self explanatory, but there is more to it

Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation

Digital-analog is a universal quantum computing paradigm which employs the natural entangling Hamiltonian of the system and single-qubit gates as resources. Here, we study the stability of these proto...

🔥 New paper: "Quantum Carleman linearization efficiency in nonlinear fluid dynamics" in #PhysRevResearch. doi.org/10.1103/Phys... Fluid dynamics is hard when things go nonlinear: turbulence, shocks, and chaotic flows. Solving it requires huge computational resources. Could quantum computing help?

This paper marks the beginning of a new (and hopefully long-lasting) theoretical-experimental collaboration with David Novoa and his outstanding group focused on developing quantum technologies based on the hollow-core optical fiber platform—a field that remains largely unexplored to date.

We propose here the first quantum model of light-matter interaction in gas-filled hollow-core fibers. We show that, in the semi-classical limit, the model recovers the traditional equations, while also enabling the prediction of entanglement dynamics during the Raman transduction process.

The Lloyd-Mohseni-Rebentrost (LMR) protocol allows for implementing matrix exponentiation when copies of a quantum state are available. However, in a realistic scenario, the copies are limited and the noncloning thm prevents one from producing exact copies to increase the accuracy of the protocol.

In this paper, we propose a method to circumvent this limitation by introducing imperfect quantum copies, which significantly improve the performance of the LMR when the eigenvectors are known.
