Low-leakage superconducting-qubit measurement with sub-100-ns total duration
Peter A. Spring, Adrian L. Hesse, Shiyu Wang +2
Fast, accurate, and low-leakage qubit measurement is a key requirement for quantum error correction. Here, we demonstrate measurement of a superconducting transmon qubit with a tot…
High-fidelity all-microwave CZ gate with partial erasure-error detection via a transmon coupler
Shotaro Shirai, Shinichi Inoue, Shuhei Tamate +3
Entangling gates between neighboring physical qubits are essential for quantum error correction. Implementing them in an all-microwave manner simplifies signal routing and control…
Selective Excitation of Superconducting Qubits with a Shared Control Line through Pulse Shaping
Ryo Matsuda, Ryutaro Ohira, Toshi Sumida +16
In conventional architectures of superconducting quantum computers, each qubit is connected to its own control line, leading to a commensurate increase in the number of microwave l…
High-Performance and Scalable Fault-Tolerant Quantum Computation with Lattice Surgery on a 2.5D Architecture
Yosuke Ueno, Taku Saito, Teruo Tanimoto +4
Due to the high error rate of a qubit, detecting and correcting errors on it is essential for fault-tolerant quantum computing (FTQC). Among several FTQC techniques, lattice surger…
Efficient tomography of microwave photonic cluster states
