Quantum simulation of the Heisenberg XXZ model on a Rydberg atom array
Matthias Werner, Artur García-Sáez
A major application of analog quantum hardware is quantum simulation, where a system evolves over time according to a given Hamiltonian. One challenge when implementing the Hamilto…
Leveraging Landau-Zener-Stückelberg interference for accelerating diabatic quantum annealing
Matthias Werner, Matías Jonsson, Artur García-Sáez +2
Diabatic quantum annealing with variationally optimized schedules can exhibit exponential speedups over conventional adiabatic quantum annealing, as was demonstrated numerically fo…
Entropy-driven entanglement forging
Axel Pérez-Obiol, Sergi Masot-Llima, Antonio M. Romero +4
Simulating physical systems with variational quantum algorithms is a well-studied approach, but it is challenging to implement in current devices due to demands in qubit number and…
Quantum simulation of one-dimensional fermionic systems with Ising Hamiltonians
Matthias Werner, Artur García-Sáez, Marta P. Estarellas
In recent years, analog quantum simulators have reached unprecedented quality, both in qubit numbers and coherence times. Most of these simulators natively implement Ising-type Ham…
