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…
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…
