Comment on "Entropic Costs of Extracting Classical Ticks from a Quantum Clock"
Longyan Gong
A recent Letter by Wadhia et al. reports a realization of a quantum clock using a double quantum dot (DQD) [Phys. Rev. Lett. 135, 200407 (2005)]. This Comment identifies two fundam…
Comment on "Reentrant Localization Transition in a Quasiperiodic Chain"
Longyan Gong, Hui Lu, Weiwen Cheng
In their Letter[Phys. Rev. Lett. 126, 106803 (2021)], the authors found an interesting reentrant localization phenomenon in a one-dimensional dimerized lattice with quasiperiodic d…
Exact Mobility Edges in One-Dimensional Mosaic Lattices Inlaid with Slowly Varying Potentials
Longyan Gong
We propose a family of one-dimensional mosaic models inlaid with a slowly varying potential , where is the lattice site index and . Combinating the asy…
Turbulence Mitigation Scheme for Optical Communications using Orbital Angular Momentum Multiplexing Based on Channel Coding and Wavefront Correction
Shengmei Zhao, Bei Wang, Li Zhou +4
The free-space optical (FSO) communication links with orbital angular momentum (OAM) multiplexing have been demonstrated that they can largely enhance the systems' capacity without…
Efficient entanglement concentration for arbitrary less-entangled N-atom state
Lan Zhou
A recent paper (Phys. Rev. A 86, 034305 (2012)) proposed an entanglement concentration protocol (ECP) for less-entangled -atom GHZ state with the help of the photonic Faraday ro…
Experimental realization of large-alphabet quantum key distribution protocol using orbital angular momentum entanglement
Shengmei Zhao, Longyan Gong, Yongqiang Li +5
We experimentally demonstrate a quantum key distribution (QKD) protocol using photon pairs entangled in orbit angular momentum (OAM). In our protocol, Alice and Bob modulate their…
