In this paper, we study optical bistability (OB) and optical multistability (OM) in a defect
medium with a monolayer of graphene quantum system. The graphene quantum system …

In this paper, we study the induced torque characteristics in Landau-quantized graphene
systems under the influence of optical vortex fields. Through numerical simulations and …

A batch quantum multi-proxy signature scheme is proposed, in which the original signatory
distributes his signing right to multiple proxy signatories, and these proxy signatories can …

An efficient quantum secret sharing scheme based on multi-dimensional GHZ state is
proposed. The dealer performs the special unitary operation on the special n-dimensional n …
