Multiplexed storage and real-time manipulation based on a multiple degree-of-freedom quantum memory
Nature Communications, 2018 Multiplexing of quantum memories would enable higher communication rate for repeater based quantum networks. Here, the authors demonstrate multiplexed storage of single-photon-level pulses using multiple degree-of-freedom, with the additional function of

Transforming Bell's Inequalities into State Classifiers with Machine Learning
, 2017 Quantum information science has profoundly changed the ways we understand, store, and process information. A major challenge in this field is to look for an efficient means for classifying quantum state. For instance, one may want to determine if a given

kHz-precision wavemeter based on reconfigurable microsoliton
Nature Communications, 2023 Microcombs are vulnerable to the environmental perturbations. Here, the authors propose a universal mechanism to fully control the microcombs. Based this reconfigurable microsoliton, a wavemeter with a precision of kHz is demonstrated.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

PATH TO QUANTUM LIFE INFORMATION SCIENCES
Quantum Bio-Informatics, 2008 As was explained in the Preface, the center QBIC was founded to seriously attempt a mutual interaction between bio-informatics and quantum information, thereby creating a new field that can be called quantum bio-informatics. The conference of the QBIC-2006 proceeding opens the 5 year program (that may be 8) for this quantum bio--informatics. This
