QPU-scale randomized benchmarking via Bell-pair injection
Haripriya Pettugani, María Aguado-Yáñez, Astryd Park +2
Mirror randomized benchmarking (MRB) is an established technique that provides a global error metric at the scale of a whole QPU. To expand upon this we introduce Mirror Quantum Aw…
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…
Procedural Generation and Games at the Dawn of Fault Tolerant Quantum Computing
Daniel Bultrini, James Wootton
Quantum computers have long been more of a toy for researchers than a tool for solving complex problems. However, recent advances in the field make exploiting the advantages of fau…
Simple Mitigation Strategy for a Systematic Gate Error in IBMQ
Daniel Bultrini, Max Hunter Gordon, Esperanza López +1
We report the observation and characterisation of a systematic error in the implementation of gates in the IBM quantum computers. The error appears as a consistent shift in o…
