Quantum Technology Initiative Journal Club

Weekly Journal Club meetings organised in the framework of the CERN Quantum Technology Initiative (QTI) to present and discuss scientific papers in the field of quantum science and technology. The goal is to help researchers keep track of current findings and walk away with ideas for their own research. Some previous knowledge of quantum physics would be helpful, but is not required to follow the talks.

16:00 Quantum variational learning for quantum error-correcting codes

Abstract:
Designing good QEC codes is in general a hard problem due to the exponentially large search and decoding space. Traditional stabilizer or concatenated codes typically require much more qubits. In this work, the authors introduce VarQEC, using VQC to find QEC code. Based on approximate QEC codition, the autors introduce cost function to learn the encoding circuits adapted to a given noise channel. This approach is universal and can find non-additive codes with smaller number of qubits. These methods may be particularly useful for discovering continuous-variable quantum error-correcting codes.
