  • Patent number: 11528133
    Abstract: This specification discloses a quantum public-key cryptosystem. The quantum public-key cryptosystem may use two rotation operators R{circumflex over (n)}(?) and R{circumflex over (m)}(?) satisfying a cyclic evolution. The two rotation operators R{circumflex over (n)}(?) and R{circumflex over (m)}(?) do not have a commutation relation or an anti-commutation relation with each other. The commutation relation or the anti-commutation relation is established when either of the following conditions is satisfied: ?=2i?, ?=2j?, or {circumflex over (n)}·{circumflex over (m)}=1 (i, j=integer), and ?=(2k+1)?, ?=(2l+1)?, or {circumflex over (n)}·{circumflex over (m)}=0 (k, l=integer).
