Benchmarking Dark Matter Search using a Parity-Check Protocol with Machine-Learning Optimized Pulses
Yu-Han Chang, Ilya Moskalenko, Marko Kuzmanović +7
We report on an improved microwave detection protocol for dark matter candidates such as the axion and the dark photon. We employ a superconducting transmon qubit dispersively coup…
Quantum Process Tomography with Digital Twins of Error Matrices
Tangyou Huang, Akshay Gaikwad, Ilya Moskalenko +19
Accurate and robust quantum process tomography (QPT) is crucial for verifying quantum gates and diagnosing implementation faults in experiments aimed at building universal quantum…
Observation of the two-photon Landau-Zener-Stückelberg-Majorana effect
Isak Björkman, Marko Kuzmanović, Gheorghe Sorin Paraoanu
Second-order processes introduce nonlinearities in quantum dynamics, unlocking a totally unexpected area of control operations. Here we show that the well-known Landau-Zener-Stücke…
High-fidelity robust qubit control by phase-modulated pulses
Marko Kuzmanović, Isak Björkman, John J. McCord +2
We present a set of robust and high-fidelity pulses that realize paradigmatic operations such as the transfer of the ground state population into the excited state and arbitrary $X…
