Ph.D. candidate in physics at EPFL. Working on Quantum Computing and Quantum Metrology.

New paper on arXiv 🔥 We present a bound that unifies all the previous guarantees of small regions with substantial gradients in BP landscapes. This allows us to study new architectures, parameter correlations, and points on the landscape that could not be analyzed before. scirate.com/arxiv/2502.0...

Nature cools things easily but getting a quantum computer to do it is hard! Give us an approx ground state, we present an algorithm that approximates imaginary time evolution to: - Cool that state by an amount proportional to its energy fluctuations - Increase its fidelity with the ground state

New preprint on arXiv! scirate.com/arxiv/2412.0... Quantum imaginary-time evolution (QITE) is amazing, but its compilation is not straightforward. We found an iterative way of doing this, using the equivalence of QITE and double-bracket flows.
