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…
On quenches to the critical point of the three states Potts model -- Matrix Product State simulations and CFT
Niall F. Robertson, Jacopo Surace, Luca Tagliacozzo
Conformal Field Theories (CFTs) have been used extensively to understand the physics of critical lattice models at equilibrium. However, the applicability of CFT calculations to th…
Lattice regularisation of a non-compact boundary conformal field theory
Niall F. Robertson, Jesper Lykke Jacobsen, Hubert Saleur
Non-compact Conformal Field Theories (CFTs) are central to several aspects of string theory and condensed matter physics. They are characterised, in particular, by the appearance o…
