Quantum Error-Corrected Computation of Molecular Energies
Kentaro Yamamoto, Yuta Kikuchi, David Amaro +18
We present the first demonstration of an end-to-end pipeline with quantum error correction (QEC) for a quantum computation of the electronic structure of molecular systems. We calc…
Hamiltonian dynamics simulation using linear combination of unitaries on an ion trap quantum computer
Michelle Wynne Sze, Yao Tang, Silas Dilkes +3
The linear combination of unitaries (LCU) method has proven to scale better than existing product formulas in simulating long time Hamiltonian dynamics. However, given the number o…
Quantum state preparation for multivariate functions
Matthias Rosenkranz, Eric Brunner, Gabriel Marin-Sanchez +5
A fundamental step of any quantum algorithm is the preparation of qubit registers in a suitable initial state. Often qubit registers represent a discretization of continuous variab…
Volumetric Benchmarking of Error Mitigation with Qermit
Cristina Cirstoiu, Silas Dilkes, Daniel Mills +2
The detrimental effect of noise accumulates as quantum computers grow in size. In the case where devices are too small or noisy to perform error correction, error mitigation may be…
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…
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…
