Measurement-Induced State Transitions in a Superconducting Qubit: Within the Rotating Wave Approximation
Mostafa Khezri, Alex Opremcak, Zijun Chen +9
Superconducting qubits typically use a dispersive readout scheme, where a resonator is coupled to a qubit such that its frequency is qubit-state dependent. Measurement is performed…
Overcoming leakage in scalable quantum error correction
Kevin C. Miao, Matt McEwen, Juan Atalaya +114
Leakage of quantum information out of computational states into higher energy states represents a major challenge in the pursuit of quantum error correction (QEC). In a QEC circuit…
Readout of a quantum processor with high dynamic range Josephson parametric amplifiers
T. C. White, Alex Opremcak, George Sterling +91
We demonstrate a high dynamic range Josephson parametric amplifier (JPA) in which the active nonlinear element is implemented using an array of rf-SQUIDs. The device is matched to…
Suppressing quantum errors by scaling a surface code logical qubit
Rajeev Acharya, Igor Aleiner, Richard Allen +154
Practical quantum computing will require error rates that are well below what is achievable with physical qubits. Quantum error correction offers a path to algorithmically-relevant…
