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…
Recursive greedy initialization of the quantum approximate optimization algorithm with guaranteed improvement
Stefan H. Sack, Raimel A. Medina, Richard Kueng +1
The quantum approximate optimization algorithm (QAOA) is a variational quantum algorithm, where a quantum computer implements a variational ansatz consisting of layers of alter…
Avoiding barren plateaus using classical shadows
Stefan H. Sack, Raimel A. Medina, Alexios A. Michailidis +2
Variational quantum algorithms are promising algorithms for achieving quantum advantage on near-term devices. The quantum hardware is used to implement a variational wave function…
Entanglement transitions from restricted Boltzmann machines
Raimel Medina, Romain Vasseur, Maksym Serbyn
The search for novel entangled phases of matter has lead to the recent discovery of a new class of ``entanglement transitions'', exemplified by random tensor networks and monitored…
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…
