Reply to Fahmi and Golshani's comment on "Quantum key distribution in the Holevo limit"

Adan Cabello

英文摘要:

As Fahmi and Golshani correctly point out, a protocol introduced in A. Cabello, Phys. Rev. Lett. 85, 5635 (2000), to show that a quantum key distribution protocol can have efficiency one (i.e., can achieve the Holevo limit), does indeed not have efficiency one. The corrected protocol, introduced in A. Cabello, Recent. Res. Devel. Physics 2, 249 (2001), is reproduced here.
