The quantum computational speed of a single Cooper Pair box
A. -S. F. Obada, D. A. M. Abo-Kahla, N. Metwally +1
The speed of computations is investigated by means of the orthogonality speed for a charged qubit interacting with a single cavity field prepared initially in a Fock state or Binom…

Dynamics of encrypted information in the presence of imperfect operations
Nasser Metwally
The original dense coding protocol is achieved via quantum channel generated between a single Cooper pair and a cavity. The dynamics of the coded and decoded information are invest…
