A commentary of“Prolonging the lifetime of logic qubits by Bosonic error-correcting code-realizing the break-even point of quantum error correction”:Top 10 Scientific Advances of 2023,China

At present,we are in the noisy-intermediate-scale-quantum era of quantum information science and technology[1],in which there are relatively large numbers of qubits with noise.For instance,the error rate of current superconducting qubits is orders of magnitude away from practical application.To solve this problem,various methods have been used,such as holonomic quantum gate[2],dynamical decoupling[3],entanglement purification[4],and quantum error correction[5].
