Helicity Entanglement of Moving Bodies
Shuxin Shao, Song He, Hongbao Zhang
We investigate the Lorentz transformation of the reduced helicity density matrix for a pair of massive spin 1/2 particles. The corresponding Wootters concurrence shows no invariant…
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…
Quantum Entanglement of Electromagnetic Fields in Non-inertial Reference Frames
Yi Ling, Song He, Weigang Qiu +1
Recently relativistic quantum information has received considerable attention due to its theoretical importance and practical application. Especially, quantum entanglement in non-i…
On the Quantum Mechanics for One Photon
Yapeng Hu, Weigang Qiu, Hongbao Zhang
This paper revisits the quantum mechanics for one photon from the modern viewpoint and by the geometrical method. Especially, besides the ordinary (rectangular) momentum representa…
