Omkar, S. Teo, Y. S. Lee, Seung-Woo Jeong, H. 2024-01-19T15:04:18Z 2024-01-19T15:04:18Z 2021-09-04 2021-03-09 2469-9926 https://pubs.kist.re.kr/handle/201004/117267 We investigate a scheme for topological quantum computing using optical hybrid qubits and make an extensive comparison with previous all-optical schemes. We show that the photon loss threshold reported by Omkar et al. [Phys. Rev. Lett. 125, 060501 (2020)] can be improved further by employing postselection and multi-Bell-state-measurement-based entangling operations to create a special cluster state, known as Raussendorf lattice for topological quantum computation. In particular, the photon loss threshold is enhanced up to 5.7 x 10(-3), which is the highest reported value given a reasonable error model. This improvement is obtained at the price of consuming more resources by an order of magnitude compared with the scheme in the aforementioned reference. Nevertheless, this scheme remains resource-efficient compared with other known optical schemes for fault-tolerant quantum computation.
