Trotter error bounds and dynamic multi-product formulas for Hamiltonian simulation
Sergiy Zhuk, Niall Robertson, Sergey Bravyi
Multi-product formulas (MPF) are linear combinations of Trotter circuits offering high-quality simulation of Hamiltonian time evolution with fewer Trotter steps. Here we report two…
Approximate Quantum Compiling for Quantum Simulation: A Tensor Network based approach
Niall F. Robertson, Albert Akhriev, Jiri Vala +1
We introduce AQCtensor, a novel algorithm to produce short-depth quantum circuits from Matrix Product States (MPS). Our approach is specifically tailored to the preparation of quan…
Escaping barren plateaus in approximate quantum compiling
Niall F. Robertson, Albert Akhriev, Jiri Vala +1
Quantum compilation provides a method to translate quantum algorithms at a high level of abstraction into their implementations as quantum circuits on real hardware. One approach t…
Evidence of Kardar-Parisi-Zhang scaling on a digital quantum simulator
Nathan Keenan, Niall Robertson, Tara Murphy +2
Understanding how hydrodynamic behaviour emerges from the unitary evolution of the many-particle Schrödinger equation is a central goal of non-equilibrium statistical mechanics. In…
