Non-Clifford Benchmarking via Ensemble Feature Selection
Stancho G. Stanchev, Nikolay V. Vitanov
We propose an Ensemble Feature Selection (EFS) method for fast estimation of process infidelity of involutory multi-qubit gates, including non-Clifford targets, for which standard…

Multipass Quantum Process Tomography: Precision and Accuracy Enhancement
Stancho G. Stanchev, Nikolay V. Vitanov
We introduce a method to enhance the precision and accuracy of Quantum Process Tomography (QPT) by mitigating the errors caused by state preparation and measurement (SPAM), readout…

Characterization of high-fidelity Raman qubit gates
Stancho G. Stanchev, Nikolay V. Vitanov
Raman qubits, represented by two ground or metastable quantum states coupled via an intermediate state, hold some advantages over directly coupled qubits, most notably much longer…
