Quantum-Guided Cluster Algorithms for Combinatorial Optimization

Peter J. Eder, Aron Kerschbaumer, Jernej Rudi Finžgar +5

Finding the ground state of Ising spin glasses is notoriously difficult due to disorder and frustration. Often, this challenge is framed as a combinatorial optimization problem, fo…

Tensor Cross Interpolation of Purities in Quantum Many-Body Systems

Dmytro Kolisnyk, Raimel A. Medina, Romain Vasseur +1

A defining feature of quantum many-body systems is the exponential scaling of the Hilbert space with the number of degrees of freedom. This exponential complexity naïvely renders a…

A Recursive Lower Bound on the Energy Improvement of the Quantum Approximate Optimization Algorithm

Raimel A. Medina, Maksym Serbyn

The Quantum Approximate Optimization Algorithm (QAOA) uses a quantum computer to implement a variational method with layers of alternating unitary operators, optimized by a cl…

Duality approach to quantum annealing of the 3-XORSAT problem

Raimel Medina, Maksym Serbyn

Classical models with complex energy landscapes represent a perspective avenue for the near-term application of quantum simulators. Until now, many theoretical works studied the pe…

Aspects of quantum information in finite density field theory

Lucas Daguerre, Raimel Medina, Mario Solis +1

We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero c…

Renyi relative entropies and renormalization group flows

Horacio Casini, Raimel Medina, Ignacio Salazar +1

Quantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measu…
