Separate and efficient characterization of state-preparation and measurement errors using single-qubit operations
Muhammad Qasim Khan, Leigh M. Norris, Lorenza Viola
In many platforms, errors from state-preparation and measurement (SPAM) dominate over single-qubit gate errors. To inform further hardware improvements and the development of more…
SPAM-Robust Multi-axis Quantum Noise Spectroscopy in Temporally Correlated Environments
Muhammad Qasim Khan, Wenzheng Dong, Leigh M. Norris +1
Characterizing temporally correlated (``non-Markovian'') noise is a key prerequisite for achieving noise-tailored error mitigation and optimal device performance. Quantum noise spe…
Provably Optimal Control for Multiplicative Amplitude Control Noise
Colin J. Trout, Kevin Schultz, Paraj Titum +3
We provide a technique to obtain provably optimal control sequences for quantum systems under the influence of time-correlated multiplicative control noise. Utilizing the circuit-l…
Two-qubit spectroscopy of spatiotemporally correlated quantum noise in superconducting qubits
Uwe von Lüpke, Félix Beaudoin, Leigh M. Norris +9
Noise that exhibits significant temporal and spatial correlations across multiple qubits can be especially harmful to both fault-tolerant quantum computation and quantum-enhanced m…
Simultaneous spectral estimation of dephasing and amplitude noise on a qubit sensor via optimally band-limited control
Virginia Frey, Leigh M. Norris, Lorenza Viola +1
The fragility of quantum systems makes them ideally suited for sensing applications at the nanoscale. However, interpreting the output signal of a qubit-based sensor is generally c…
Extending comb-based spectral estimation to multiaxis quantum noise
Gerardo A. Paz-Silva, Leigh M. Norris, Félix Beaudoin +1
We show how to achieve full spectral characterization of general multiaxis additive noise. Our pulsed spectral estimation technique is based on sequence repetition and frequency-co…
