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…
Polynomial equivalence of the global transverse-field Ising model and the gate model of quantum computation
Matthias Werner
The transverse-field Ising model has attracted a lot of attention in recent years, especially in the quantum simulation and quantum computation literature. This interest is driven…
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…
A quantum state transfer protocol with Ising Hamiltonians
Oscar Michel, Matthias Werner, Arnau Riera
Quantum state transfer is a fundamental requirement for scalable quantum computation, where fast and reliable communication between distant subsystems is essential. In this work, w…
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…
