Probabilistic error cancellation for dynamic quantum circuits
Riddhi S. Gupta, Ewout van den Berg, Maika Takita +3
Probabilistic error cancellation (PEC) is a technique that generates error-mitigated estimates of expectation values from ensembles of quantum circuits. In this work we extend the…
Realizing the Nishimori transition across the error threshold for constant-depth quantum circuits
Edward H. Chen, Guo-Yi Zhu, Ruben Verresen +9
Preparing quantum states across many qubits is necessary to unlock the full potential of quantum computers. However, a key challenge is to realize efficient preparation protocols w…
Classical benchmarking of zero noise extrapolation beyond the exactly-verifiable regime
Sajant Anand, Kristan Temme, Abhinav Kandala +1
In a recent work a quantum error mitigation protocol was applied to the expectation values obtained from circuits on the IBM Eagle quantum processor with up - qubits with up…
