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…

Two quantum Ising algorithms for the Shortest Vector Problem: one for now and one for later
David Joseph, Adam Callison, Cong Ling +1
Quantum computers are expected to break today's public key cryptography within a few decades. New cryptosystems are being designed and standardised for the post-quantum era, and a…

Finding spin-glass ground states using quantum walks
Adam Callison, Nicholas Chancellor, Florian Mintert +1
Quantum computation using continuous-time evolution under a natural hardware Hamiltonian is a promising near- and mid-term direction toward powerful quantum computing hardware. We…
