A graphene edge-mediated quantum gate

Phillip Weinberg, Adrian E. Feiguin

We propose a quantum gate architecture that allows for the systematic control of the effective exchange interactions between magnetic impurities embedded in nano-scale graphene fla…

Enhanced Convergence of Quantum Typicality using a Randomized Low-Rank Approximation

Phillip Weinberg

We present a method to reduce the variance of stochastic trace estimators used in quantum typicality (QT) methods via a randomized low-rank approximation of the finite-temperature…

Scaling and diabatic effects in quantum annealing with a D-Wave device

Phillip Weinberg, Marek Tylutki, Jami M. Rönkkö +5

We discuss quantum annealing of the two-dimensional transverse-field Ising model on a D-Wave device, encoded on lattices with . Analyzing the residual energy…

Symmetry enhanced first-order phase transition in a two-dimensional quantum magnet

Bowen Zhao, Phillip Weinberg, Anders W. Sandvik

Theoretical studies of quantum phase transitions have suggested critical points with higher symmetries than those of the underlying Hamiltonian. Here we demonstrate a surprising em…

Anomalous quantum-critical scaling corrections in two-dimensional antiferromagnets

Nvsen Ma, Phillip Weinberg, Hui Shao +3

We study the Néel-paramagnetic quantum phase transition in two-dimensional dimerized Heisenberg antiferromagnets using finite-size scaling of quantum Monte Carlo data. We r…
