NISQ2LSQ - From NISQ to LSQ: Bosonic and LDPC codes
This project aims to accelerate R&D efforts in the theory and design of hardware-efficient fault-tolerant quantum codes.
In this context, the Quantum Dot research group will focus specifically on the development of photonic quantum codes.
Among the most promising solutions, the project will explore bosonic codes, particularly cat codes, and Low-Density Parity-Check (LDPC) codes.
On the hardware side, the targeted platforms include superconducting qubits and, crucially, photonic architectures. A key objective is to define and experimentally realize computational architectures within the Measurement-Based Quantum Computation (MBQC) framework, leveraging both cat codes and LDPC codes to optimize scalability in photonic systems.
For LDPC codes, the focus will be on designing optimal encoding and error-correction schemes, developing efficient decoding algorithms, and implementing fault-tolerant logical operations specific to LDPC. To ensure seamless integration with photonic or Rydberg-atom-based technologies, the research will prioritize compact codes with minimal long-range interactions.
By the end of the project, these advancements will contribute to the broader goal of scaling up towards a Large-Scale Quantum (LSQ) computer, with photonic architectures playing a central role in this effort.
