Autonomous error correction of a single logical qubit using two transmons

2023 · arXiv (Cornell University)

Large-scale quantum computers will inevitably need quantum error correction to protect information against decoherence. Traditional error correction typically requires many qubits, along with high-efficiency error syndrome measurement and real-time feedback. Autonomous quantum error correction (AQEC) …

Implementation of a Quantum Addressable Router Using Superconducting Qubits

2025 · arXiv (Cornell University)

The implementation of a quantum router capable of performing both quantum signal routing and quantum addressing (a Q2-router) represents a key step toward building quantum networks and quantum random access memories. We realize a Q2-router …
