Spacetime mitigation of logical errors
Laurin E. Fischer, Ali Javadi-Abhari, Simon Martiel +1
Error detection can suppress noise at a lower sampling cost than probabilistic error cancellation (PEC), but leaves residual logical errors. We combine the two approaches to mitiga…
Enabling large-scale digital quantum simulations with superconducting qubits
Laurin E. Fischer
Quantum computing promises to revolutionize several scientific and technological domains through fundamentally new ways of processing information. Among its most compelling applica…
Large-scale implementation of quantum subspace expansion with classical shadows
Laurin E. Fischer, Daniel Bultrini, Ivano Tavernelli +1
Quantum subspace expansion (QSE) offers promising avenues to perform spectral calculations on quantum processors but comes with a large measurement overhead. Informationally comple…
Mitigating errors in state preparation and measurement with noncomputational states
