Feasibility and parameter optimization of ground-to-satellite uplink continuous-variable quantum key distribution by Jin Cheng, Yujie Chen, Ao Liu, Xin Sun, Junjie Guo, Bohan Yang, Peng Yin, Wenbo Liu, Lanjian Chen, Chen Dong

“…Driven by the necessitates of wide-area quantum secure communication networks, ground-to-satellite quantum key distribution (QKD) has been highlighted in the field of quantum information. Continuous variable QKD (CV-QKD) shows the advantages of a high secure key rate generation and compatibility in the fiber channel, but the communication range is limited by low attenuation tolerance. …”

Large‐Area Bright Emission of Plasmon‐Coupled Dark Excitons at Room Temperature by Hyun Jeong, Hyeong Chan Suh, Ga Hyun Cho, Huitae Joo, Yeonjeong Koo, Hayoung Ko, Ki Kang Kim, Youngbum Kim, Jeongyong Kim, Kyoung‐Duck Park, Mun Seok Jeong

“…Abstract Brightening dark excitons in transition metal dichalcogenide monolayers (MLs) can provide large‐area ultrathin devices for applications in quantum information science and optoelectronics. For practical applications of dark excitons, a robust and bright emission over a wide area at room temperature is desirable; however, no reliable approach has been demonstrated thus far. …”

Mapping indefinite causal order processes to composable quantum protocols in a spacetime by Matthias Salzger, V Vilasini

“…To address these points, we compare the formalism of quantum circuits with quantum control of causal order (QC-QC), which models an interesting class of ICS processes, with that of causal boxes, which models composable quantum information protocols in spacetime. We incorporate the set-up assumptions of the QC-QC framework into the spatiotemporal perspective and show that every QC-QC can be mapped to a causal box that satisfies these set up assumptions and acts on a Fock space while reproducing the QC-QC’s behaviour in a relevant subspace defined by the assumptions. …”
