Frozen quantum coherence

HIGHLIGHTS

• who: . et al. from the School of Mathematical Sciences, The University of Nottingham, University Park, Nottingham , RD, United Kingdom have published the Article: Frozen Quantum Coherence, in the Journal: (JOURNAL) of 29/05/2015
• what: In this Letter the authors investigate the dynamics of quantum coherence in open quantum systems under paradigmatic incoherent noisy channels. The authors show that no nontrivial condition exists such that both measures are simultaneously frozen. The authors focus on bit-flip channels ΛF1 and coherence in the computational basis (eigenbasis of σ 3 ) for illustration; however, analogous results hold for the . . .
