Fault-tolerant quantum algorithms for simulating atomic nuclei
James Benstead, Michael Garn, Neil Gaspar +5
To maximize the value of fault-tolerant quantum computers, it is essential to develop concrete applications beyond well-established domains such as chemistry and condensed-matter p…
A case study against QSVT: assessment of quantum phase estimation improved by signal processing techniques
Sean Greenaway, William Pol, Sukin Sim
In recent years, quantum algorithms have been proposed which use quantum phase estimation (QPE) coherently as a subroutine without measurement. In order to do this effectively, the…
Analogue Quantum Simulation with Fixed-Frequency Transmon Qubits
Sean Greenaway, Adam Smith, Florian Mintert +1
We experimentally assess the suitability of transmon qubits with fixed frequencies and fixed interactions for the realization of analogue quantum simulations of spin systems. We te…
Variational Quantum Gate Optimization at the Pulse Level
Sean Greenaway, Francesco Petiziol, Hongzheng Zhao +1
We experimentally investigate the viability of a variational quantum gate optimization protocol informed by the underlying physical Hamiltonian of fixed-frequency transmon qubits.…
Efficient Assessment of Process Fidelity
Sean Greenaway, Frédéric Sauvage, Kiran E. Khosla +1
The accurate implementation of quantum gates is essential for the realisation of quantum algorithms and digital quantum simulations. This accuracy may be increased on noisy hardwar…
Simple Mitigation of Global Depolarizing Errors in Quantum Simulations
Joseph Vovrosh, Kiran E. Khosla, Sean Greenaway +3
To get the best possible results from current quantum devices error mitigation is essential. In this work we present a simple but effective error mitigation technique based on the…
