Quantum secure data transfer with pulse shape encoded optical qubits

Quantum secure data transfer is an important topic for quantum cyber security. We propose a scheme to realize in the basis of direct communication (QSDC). In this proposal, transmitted encoded pulse shape single optical qubit, which emitted from trapped atom owned by sender and received receiver with another atom. The encoding process can be implemented high fidelity controlling time-dependent driving on manipulate Rabi frequency accordance target photons. receiving process, we prove that, photon absorbed arbitrary probability selecting appropriate pulse. also show based QSDC protocol, immune individual attacks.
