Reference-frame-independent quantum key distribution (RFI QKD) can generate secret keys without the alignment of reference frames,which is very robust in real-l
We investigate the entropy squeezing of a two-level atom in the Jaynes-Cummings model,and provide a scheme to generate the sustained optimal entropy squeezing o
We report the fabrication of a planar waveguide in the Nd∶Bi12SiO20 crystal by multi-energy C ions at room temperature.The waveguide is annealed at 200 ℃,260
With the increasing popularity of fingerprint identification technology,its security and privacy have been paid much attention.Only the security and privacy of
