Sign-optimized Quantum Monte Carlo
Julius S. Herz, Robin Schäfer, Matías G. Gonzalez +1
The sign problem breaks the polynomial scaling of Quantum Monte Carlo methods. We alleviate it by rotation of the local basis of the Hilbert space, such that the phase of off-diago…
Disorder-enhanced compressibility of Floquet random quantum circuits
Francesca De Franco, Dante M. Kennes, David J. Luitz +2
Current quantum hardware is limited by noise and decoherence, which restrict the depth of unitary circuits that can be implemented with high fidelity. We investigate how the compre…
Hamiltonian Monte Carlo enhanced by Exact Diagonalization
Finn L. Temmen, Martina Gisti, David J. Luitz +2
Strongly correlated fermionic systems are of great interest in condensed matter physics and numerical methods are indispensable tools for their study. However, existing approaches…
Random matrix perspective on probabilistic error cancellation
Leonhard Moske, Pedro Ribeiro, Tomaž Prosen +3
Probabilistic error cancellation is an attempt to reverse the effect of dissipative noise channels on quantum computers by applying unphysical channels after the execution of a qua…
Thermodynamics of the Heisenberg antiferromagnet on the maple-leaf lattice
Robin Schäfer, Paul L. Ebert, Noah Hassan +3
We study the Heisenberg antiferromagnet on the maple-leaf lattice using several numerical approaches, focusing on the numerical linked-cluster expansion (NLCE), which exhibits an u…
Quantum process tomography of a compressed time evolution circuit on superconducting quantum processors
Maria Dinca, David J. Luitz, Maxime Debertolis
As present day quantum hardware is limited by various noise mechanisms, quantum advantage can only be reached in the near-term by designing noise-resilient quantum algorithms. In t…
