Mitigating Errors on Superconducting Quantum Processors through Fuzzy Clustering
Halima G. Ahmad, Roberto Schiattarella, Pasquale Mastrovito +10
Quantum utility has been severely limited in superconducting quantum hardware until now by the modest number of qubits and the relatively high level of control and readout errors,…
Entanglement assisted probe of the non-Markovian to Markovian transition in open quantum system dynamics
Chandrashekhar Gaikwad, Daria Kowsari, Carson Brame +8
We utilize a superconducting qubit processor to experimentally probe non-Markovian dynamics of an entangled qubit pair. We prepare an entangled state between two qubits and monitor…
