A Generic Compilation Strategy for the Unitary Coupled Cluster Ansatz
Alexander Cowtan, Will Simmons, Ross Duncan
We describe a compilation strategy for Variational Quantum Eigensolver (VQE) algorithms which use the Unitary Coupled Cluster (UCC) ansatz, designed to reduce circuit depth and gat…
tket : A Retargetable Compiler for NISQ Devices
Seyon Sivarajah, Silas Dilkes, Alexander Cowtan +3
We present tket, a quantum software development platform produced by Cambridge Quantum Computing Ltd. The heart of tket is a language-agnostic optimising co…
Dynamical mean field theory algorithm and experiment on quantum computers
I. Rungger, N. Fitzpatrick, H. Chen +12
The developments of quantum computing algorithms and experiments for atomic scale simulations have largely focused on quantum chemistry for molecules, while their application in co…
Phase Gadget Synthesis for Shallow Circuits
Alexander Cowtan, Silas Dilkes, Ross Duncan +2
We give an overview of the circuit optimisation methods used by tket, a compiler system for quantum software developed by Cambridge Quantum Computing Ltd. We focus on a novel techn…
On the qubit routing problem
Alexander Cowtan, Silas Dilkes, Ross Duncan +3
We introduce a new architecture-agnostic methodology for mapping abstract quantum circuits to realistic quantum computing devices with restricted qubit connectivity, as implemented…
