Detailed, interpretable characterization of mid-circuit measurement on a transmon qubit
Piper C. Wysocki, Luke D. Burkhart, Madeline H. Morocco +12
Mid-circuit measurements (MCMs) are critical components of the quantum error correction protocols expected to enable utility-scale quantum computing. MCMs can be modeled by quantum…
Efficient Qubit Calibration by Binary-Search Hamiltonian Tracking
Fabrizio Berritta, Jacob Benestad, Lukas Pahl +14
We present and experimentally implement a real-time protocol for calibrating the frequency of a resonantly driven qubit, achieving exponential scaling in calibration precision with…
Improving Transmon Qubit Performance with Fluorine-based Surface Treatments
Michael A. Gingras, Bethany M. Niedzielski, Kevin A. Grossklaus +21
Reducing materials and processing-induced decoherence is critical to the development of utility-scale quantum processors based on superconducting qubits. Here we report on the impa…
Observation of Photon Blockade in a Tavis-Cummings System
Brian Marinelli, Alex H. Rubin, Victoria A. Norman +10
We observe blockade of microwave photons in a Tavis-Cummings system comprising a superconducting cavity and up to transmon qubits. The effect is characterized with photon num…
