DOI: 10.1007/s11128-017-1646-3
Abstract: We present a new scheme to provide an arbitrary four-photon polarization-entangled state, which enables the encoding of single logical qubit information into a four-qubit decoherence-free subspace robustly against collective decoherence. With the assistance of the… read more here.

DOI: 10.1088/1367-2630/ade61c
Abstract: The linear Breit–Wheeler (LBW) process—the production of an electron–positron pair through the collision of two high-energy photons—can emerge as the dominant pair production mechanism in the ultraintense laser-plasma interaction for laser intensities below 1023 W cm−2. Here,… read more here.

DOI: 10.1103/physrevd.104.056017
Abstract: We calculate the absorptive part of the photon polarization tensor in a hot magnetized relativistic plasma. In the derivation, we utilize a Landau-level representation for the fermion Green’s function in a mixed coordinate-momentum space and… read more here.
