Quantum error correction of a grid-state qubit with state preparation and measurement errors below
Sara Turcotte, Lucas St-Jean, Amélie L. Pessonneaux +10
Grid state qubits offer a hardware-efficient approach to large-scale fault-tolerant quantum computing. They access the information redundancy required for quantum error correction…
Hardware-Efficient Fault Tolerant Quantum Computing with Bosonic Grid States in Superconducting Circuits
Marc-Antoine Lemonde, Dany Lachance-Quirion, Guillaume Duclos-Cianci +5
Quantum computing holds the promise of solving classically intractable problems. Enabling this requires scalable and hardware-efficient quantum processors with vanishing error rate…
Autonomous quantum error correction of Gottesman-Kitaev-Preskill states
Dany Lachance-Quirion, Marc-Antoine Lemonde, Jean Olivier Simoneau +12
The Gottesman-Kitaev-Preskill (GKP) code encodes a logical qubit into a bosonic system with resilience against single-photon loss, the predominant error in most bosonic systems. He…
Dissipation-based Quantum Sensing of Magnons with a Superconducting Qubit
