High-performance local decoders for defect matching in 1D
Louis Paletta, Anthony Leverrier, Mazyar Mirrahimi +1
Local decoders, also known as cellular-automaton decoders, offer a promising path toward real-time quantum error correction by replacing centralized classical decoding, with inhere…
Fault-Tolerant Constant-Depth Clifford Gates on Toric Codes
Alexandre Guernut, Christophe Vuillot
We propose and simulate the performance of a set of fault-tolerant and constant-depth logical gates on 2D toric codes. This set combines fold-transversal gates, Dehn twists and sin…
Letting the tiger out of its cage: bosonic coding without concatenation
Yijia Xu, Yixu Wang, Christophe Vuillot +1
Continuous-variable cat codes are encodings into a single photonic or phononic mode that offer a promising avenue for hardware-efficient fault-tolerant quantum computation. Protect…
Optimal number of parametrized rotations and Hadamard gates in parametrized Clifford circuits with non-repeated parameters
Vivien Vandaele, Simon Perdrix, Christophe Vuillot
We present an efficient algorithm to reduce the number of non-Clifford gates in quantum circuits and the number of parametrized rotations in parametrized quantum circuits. The meth…
Towards Scalable Bosonic Quantum Error Correction
Barbara M. Terhal, Jonathan Conrad, Christophe Vuillot
We review some of the recent efforts in devising and engineering bosonic qubits for superconducting devices, with emphasis on the Gottesman-Kitaev-Preskill (GKP) qubit. We present…
Code Deformation and Lattice Surgery Are Gauge Fixing
Christophe Vuillot, Lingling Lao, Ben Criger +3
The large-scale execution of quantum algorithms requires basic quantum operations to be implemented fault-tolerantly. The most popular technique for accomplishing this, using the d…
