Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Polarization-encoded single-photon qubit and single-photon entanglement are important resources of quantum communication. In practical long-distance quantum communication, photon transmission loss caused by the channel noise is a big obstacle. Noiseless linear amplification (NLA) is a useful method to solve the photon transmission loss problem. In the paper, we propose two efficient NLA protocols for the polarization-encoded single-photon qubit and single-photon entanglement, respectively. Our NLA protocols can increase the fidelity of the target photon state and perfectly preserve the encoded polarization feature. Moreover, local-quadrature squeezing operation is introduced into the NLA protocols to further improve the amplification. Our NLA protocols have important application in future quantum communication field.
