Efficient recovery of variational quantum algorithms landscapes using classical signal processing
Enrico Fontana, Ivan Rungger, Ross Duncan +1
We employ spectral analysis and compressed sensing to identify settings where a variational algorithm's cost function can be recovered purely classically or with minimal quantum co…
Spectral analysis for noise diagnostics and filter-based digital error mitigation
Enrico Fontana, Ivan Rungger, Ross Duncan +1
We investigate the effects of noise on parameterised quantum circuits using spectral analysis and classical signal processing tools. For different noise models, we quantify the add…
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…
