Abstract
In the standard protocol, the maximum possible efficiency was 50%. This inefficiency could be eliminated by storing photons until the correct basis allows to measure the photons correctly 100% of the time, while preventing information from being used maliciously. This increases the effective data rate of the standard BB84 protocol considerably, and makes six-state protocols practical alternatives. This paper presents a delayed-choice quantum cryptography where a novel protocol, incorporating an optical storage system, achieves substantially higher effective data rates for quantum key distribution.
