Technical Paper: Suppressing Logical Errors with Multimode Quantum Error Correction
Nord Quantique – May 28, 2025 I. INTRODUCTION Quantum error correction (QEC) is essential for fault-tolerant quantum computing, ensuring that logical information remains protected from physical noise during the execution of quantum algorithms. Traditional QEC strategies achieve this by redundantly encoding logical qubits across many physical two-level systems (qubits), but this approach incurs significant hardware […]
Pushing the Limits of Quantum Error Correction with High-Performance Quantum Simulation
To unlock the full potential of quantum computers, we must first overcome quantum’s biggest challenge: errors. Quantum systems are tremendously fragile with even the slightest disturbance affecting the quantum state. This fundamental obstacle has made achieving reliable, large-scale quantum information processing extremely challenging. That’s why quantum error correction is so crucial to the advancement of […]

What are bosonic codes and why do we love them?
The fundamental components that allow a quantum computer to carry out computations are its qubits. A qubit can store quantum information in any of the two logical states, 0 and 1, like a classical bit, but also in some superposition of these two states — that’s what makes them quantum! Logical states are abstract, though. […]
