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…
Quasiparticle pairing encoding of atomic nuclei for quantum annealing
Emanuele Costa, Axel Pérez-Obiol, Javier Menéndez +3
Quantum computing is emerging as a promising tool in nuclear physics. However, the cost of encoding fermionic operators hampers the application of algorithms in current noisy quant…
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…
