Analogue quantum simulation with polylogarithmic interaction strengths by extrapolating within phases of matter
Dylan Harley, Matthias Christandl
Simple families of quantum Hamiltonians can simulate general many-body systems at arbitrary precision through the use of perturbative gadgets, however this generally requires inter…

Fault-Tolerant One-Shot Entanglement Generation with Constant-Sized Quantum Devices in the Plane
Dylan Harley, Robert Koenig
Consider a rectangular grid of qubits in 2D with single-qubit and nearest-neighbor two-qubit operations subject to local stochastic Pauli noise. At different length scales, this se…
