Fault-tolerant bosonic quantum error correction with the surface–Gottesman-Kitaev-Preskill code
The performance of the circuit-based surface-GKP bosonic quantum error correction code under noise due to finite squeezing of the GKP states and photon losses is investigated. The authors show underExpand

Implementation-independent sufficient condition of the Knill-Laflamme type for the autonomous protection of logical qudits by strong engineered dissipation
Autonomous quantum error correction utilizes the engineered coupling of a quantum system to a dissipative ancilla to protect quantum logical states from decoherence. We show that the Knill-LaflammeExpand

Efficient classical simulation of noisy random quantum circuits in one dimension
TLDR
We study noisy random circuit sampling in one dimension (or 1D noisy RCS) as a simple model for exploring the effects of noise on the computational power of a noisy quantum device. Expand

Quantum information processing with bosonic qubits in circuit QED
TLDR
In this paper, we review recent developments in the theory and implementation of quantum error correction with bosonic codes and report the progress made towards realizing fault-tolerant quantum information processing with cQED devices. Expand

Quantum repeaters based on concatenated bosonic and discrete-variable quantum codes
TLDR
We propose a novel architecture of quantum-error-correction-based quantum repeaters that combines the techniques used in discrete and continuous-variable quantum information. Expand
Enhanced quantum communication over Gaussian thermal loss channels using correlated multi-mode thermal states
Quantum capacity of a noisy quantum channel characterizes the channel's maximum achievable quantum communication rate (upon optimal quantum error correction or one-way entanglement distillation) andExpand

Very low overhead fault-tolerant magic state preparation using redundant ancilla encoding and flag qubits
TLDR
We propose a fault-tolerant scheme for directly preparing high-quality magic states using a two-dimensional color code architecture requiring only nearest-neighbor interactions. Expand

Path-Independent Quantum Gates with Noisy Ancilla.
TLDR
We propose a general framework that integrates quantum control and quantum error correction, so that we can achieve robust quantum gates resilient to ancilla noise. Expand
