Locality of temperature and correlations in the presence of non-zero-temperature phase transitions

Senaida Hernández Santana, Andras Molnar, Christian Gogolin +2

While temperature is well understood as an intensive quantity in standard thermodynamics, it is less clear whether the same holds in the presence of strong correlations, especially…

Avoiding local minima in variational quantum eigensolvers with the natural gradient optimizer

David Wierichs, Christian Gogolin, Michael Kastoryano

We compare the BFGS optimizer, ADAM and Natural Gradient Descent (NatGrad) in the context of Variational Quantum Eigensolvers (VQEs). We systematically analyze their performance on…

Simulating quantum chemistry in the seniority-zero space on qubit-based quantum computers

Vincent E. Elfving, Marta Millaruelo, José A. Gámez +1

Accurate quantum chemistry simulations remain challenging on classical computers for problems of industrially relevant sizes and there is reason for hope that quantum computing may…
