Automatic Post-selection by Ancillae Thermalisation
Lewis Wright, Fergus Barratt, James Dborin +2
Tasks such as classification of data and determining the groundstate of a Hamiltonian cannot be carried out through purely unitary quantum evolution. Instead, the inherent non-unit…
Parallel Quantum Simulation of Large Systems on Small Quantum Computers
Fergus Barratt, James Dborin, Matthias Bal +3
Tensor networks permit computational and entanglement resources to be concentrated in interesting regions of Hilbert space. Implemented on NISQ machines they allow simulation of qu…
Optimal local unitary encoding circuits for the surface code
Oscar Higgott, Matthew Wilson, James Hefford +4
The surface code is a leading candidate quantum error correcting code, owing to its high threshold, and compatibility with existing experimental architectures. Bravyi et al. (2006)…
