However, existing DIQKD security proofs have low noise tolerances, making a proof-of-principle demonstration currently infeasible. We investigate whether the noise tolerance can be improved by using advantage distillation, which refers to using two-way communication instead of the one-way error correction currently used in DIQKD security proofs. We derive an efficiently verifiable condition to certify that advantage distillation is secure against collective attacks in a variety of DIQKD scenarios, and use this to show that it can indeed allow higher noise tolerances, which could help to pave the way towards an experimental implementation of DIQKD. | Source Title: | Physical Review Letters | URI: | https://scholarbank.nus.edu.sg/handle/10635/167998 | ISSN: | 0031-9007 | DOI: | 10.1103/PhysRevLett.124.020502 | Rights: | Attribution-NonCommercial-NoDerivatives 4.0 International |
