Faithful qubit transmission against collective noise without ancillary qubits
Xi-Han Li, Fu-Guo Deng, Hong-Yu Zhou
We present a faithful qubit transmission scheme with linear optics against collective noise, not resorting to ancillary qubits. Its set-up is composed of three unbalanced polarizat…

Entanglement Entropy: Helicity versus Spin
Song He, Shuxin Shao, Hongbao Zhang
For a massive spin 1/2 field, we present the reduced spin and helicity density matrix, respectively, for the same pure one particle state. Their relation has also been developed. F…

Quantum Helicity Entropy of Moving Bodies
Song He, Shuxin Shao, Hongbao Zhang
Lorentz transformation of the reduced helicity density matrix for a massive spin 1/2 particle is investigated in the framework of relativistic quantum information theory for the fi…
