  • Publication number: 20200287714
    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).

  • Publication number: 20190055342
    Abstract: The present invention relates to a thermoplastic polyurethane composition imparted with crosslinking sites, which comprise a thermoplastic polyurethane containing crosslinking sites incorporated into the molecule of a polyol and/or a chain extender. The thermoplastic polyurethane composition has an easy-to-process viscosity at a processing temperature of about 130° C. or below in a low-temperature foaming process that is performed using an existing EVA crosslinking/foaming system. Thus, the thermoplastic polyurethane composition may be easily mixed with a crosslinking agent, a foaming agent and various additives, and when it is press-molded or injection-molded to provide a crosslinked foam, foam cells are easily formed by the crosslinking sites incorporated into the molecule of the polyol and/or the chain extender.
