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…
Computational complexity of injective projected entangled pair states
Dylan Harley, Freek Witteveen, Daniel Malz
Projected entangled pair states (PEPS) constitute a variational family of quantum states with area-law entanglement. PEPS are particularly relevant and successful for studying grou…
High ground state overlap via quantum embedding methods
Mihael Erakovic, Freek Witteveen, Dylan Harley +7
Quantum computers can accurately compute ground state energies using phase estimation, but this requires a guiding state that has significant overlap with the true ground state. Fo…
