Quantum optimization with exact geodesic transport
André J. Ferreira-Martins, Renato M. S. Farias, Giancarlo Camilo +6
We introduce an architecture for variational quantum algorithms that can be efficiently trained via parameter updates along exact geodesics on the Riemannian state manifold. This f…
Compilation-informed probabilistic logical-error cancellation
Giancarlo Camilo, Thiago O. Maciel, Allan Tosta +4
The potential of quantum computers to outperform classical ones in practically useful tasks remains challenging in the near term due to scaling limitations and high error rates of…
Disentangling quantum autoencoder
Adithya Sireesh, Abdulla Alhajri, M. S. Kim +1
Entangled quantum states are highly sensitive to noise, which makes it difficult to transfer them over noisy quantum channels or to store them in quantum memory. Here, we propose t…
Non-classicality at equilibrium and efficient predictions under non-commuting charges
Lodovico Scarpa, Nishan Ranabhat, Amit Te'eni +4
A quantum thermodynamic system can conserve non-commuting observables, but the consequences of this phenomenon on relaxation are still not fully understood. We investigate this pro…
Observable Statistical Mechanics
Lodovico Scarpa, Abdulla Alhajri, Vlatko Vedral +1
Predicting the stationary behavior of observables in isolated many-body quantum systems is a central challenge in quantum statistical mechanics. While one can often use the Gibbs e…
Universal quantum theory contains twisted logic
Francesco Atzori, Enrico Rebufello, Maria Violaris +9
Quantum theory is notoriously counterintuitive, and yet remains entirely self-consistent when applied universally. Here we uncover a new manifestation of its unusual consequences.…
