The Strategic importance of Quantum Communication and QEC (Quantum Error Correction)

The Bell Pairs are the most critical component of a Quantum Communication network.

If you purify the Bell Pairs using Quantum Error Correction (Bivariate Bi Cyclic codes) then the photons will carry Quantum information over multi hop networks in any of the popular network topologies.

The book by Nielsen and Chuang will help in understanding QC and the Book 

"Quantum Networking by Rodney Van Meter" will help in understanding QNwkng.

Laser controls the spinning of electrons and polarization and angle of rotation are interrelated.

The laser is produced by Single Photon Sources and it is detected by Single Photon Detectors.
