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…
Optimization of Two-Qubit Gates in Tunable-Coupler Architectures Using Single Flux Quantum Control
Boyan Torosov, Bohdan Kulchytskyy, Florian Hopfmueller +3
We present a gradient-based method to construct high-fidelity, two-qubit quantum gates in a system consisting of two transmon qubits coupled via a tunable coupler. In particular, w…
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…
Bosonic Pauli+: Efficient Simulation of Concatenated Gottesman-Kitaev-Preskill Codes
Florian Hopfmueller, Maxime Tremblay, Philippe St-Jean +2
A promising route towards fault-tolerant quantum error correction is the concatenation of a Gottesman-Kitaev-Preskill (GKP) code with a qubit code. Development of such concatenated…
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…
Compact Pulse Schedules for High-Fidelity Single-Flux Quantum Qubit Control
Ross Shillito, Florian Hopfmueller, Bohdan Kulchytskyy +1
In the traditional approach to controlling superconducting qubits using microwave pulses, the field of pulse shaping has emerged in order to assist in the removal of leakage and in…
Neural Error Mitigation of Near-Term Quantum Simulations
Elizabeth R. Bennewitz, Florian Hopfmueller, Bohdan Kulchytskyy +2
Near-term quantum computers provide a promising platform for finding ground states of quantum systems, which is an essential task in physics, chemistry, and materials science. Near…
