Classical simulations of noisy variational quantum circuits
Enrico Fontana, Manuel S. Rudolph, Ross Duncan +2
Noise detrimentally affects quantum computations so that they not only become less accurate but also easier to simulate classically as systems scale up. We construct a classical si…
Distributing circuits over heterogeneous, modular quantum computing network architectures
Pablo Andres-Martinez, Tim Forrer, Daniel Mills +5
We consider a heterogeneous network of quantum computing modules, sparsely connected via Bell states. Operations across these connections constitute a computational bottleneck and…
Tierkreis: A Dataflow Framework for Hybrid Quantum-Classical Computing
Seyon Sivarajah, Lukas Heidemann, Alan Lawrence +1
We present Tierkreis, a higher-order dataflow graph program representation and runtime designed for compositional, quantum-classical hybrid algorithms. The design of the system is…
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…
