We propose an arbitrated quantum signature (AQS) scheme with continuous variable (CV) squeezed vacuum states,which requires three parties,i.e.,the signer Alice,
We investigated the sensitivities of atom interferometers in the usual fringe-scanning method (FSM) versus the fringe-locking method (FLM). The theoretical anal
The design of the active region structures, including the modifications of structures of the quantum barrier (QB) and electron blocking layer (EBL), in the deep
