AKLT-states as ZX-diagrams: diagrammatic reasoning for quantum states
Richard D. P. East, John van de Wetering, Nicholas Chancellor +1
From Feynman diagrams to tensor networks, diagrammatic representations of computations in quantum mechanics have catalysed progress in physics. These diagrams represent the underly…
Fluctuation guided search in quantum annealing
Nicholas Chancellor
Quantum annealing has great promise in leveraging quantum mechanics to solve combinatorial optimisation problems. However, to realize this promise to it's fullest extent we must ap…
Search range in experimental quantum annealing
Nicholas Chancellor, Viv Kendon
We construct an Ising Hamiltonian with an engineered energy landscape such that it has a local energy minimum which is near to the true global minimum solution, and further away fr…
An energetic perspective on rapid quenches in quantum annealing
Adam Callison, Max Festenstein, Jie Chen +3
There are well developed theoretical tools to analyse how quantum dynamics can solve computational problems by varying Hamiltonian parameters slowly, near the adiabatic limit. On t…
Toward a standardized methodology for constructing quantum computing use cases
Nicholas Chancellor, Robert Cumming, Tim Thomas
We propose a standardized methodology for developing and evaluating use cases for quantum computers and quantum inspired methods. This methodology consists of a standardized set of…
Error measurements for a quantum annealer using the one-dimensional Ising model with twisted boundaries
Nicholas Chancellor, Philip J. D. Crowley, Tanja Đurić +5
A finite length ferromagnetic chain with opposite spin polarisation imposed at its two ends is one of the simplest frustrated spin models. In the clean classical limit the domain w…
The challenge and opportunities of quantum literacy for future education and transdisciplinary problem-solving
Laurentiu Nita, Laura Mazzoli Smith, Nicholas Chancellor +1
Resulting from cross-disciplinary dialogue between physicists, computer scientists, educationalists, and industrial end users, we propose the concept of quantum literacy as one mea…
Quantum Computing for Quantum Tunnelling
Steven Abel, Nicholas Chancellor, Michael Spannowsky
We demonstrate how quantum field theory problems can be embedded on quantum annealers. The general method we use is a discretisation of the field theory problem into a general Isin…
