Abstract
En 中文
Since it was noted that quantum computers could break public key cryptosystems based on number theory, extensive studies have been undertaken on quantum cryptography (QC), which offers unconditionally secure communication based on quantum mechanics. This paper describes QC technologies, introduces a typical and widely used QC protocol BB84 and then describes a recently proposed scheme called the differential-phase-shift protocol.
