Ferroelectric Tunnel Junction Enables Superior Neuro-Inspire...[2022-02-23]
Conventional von Neumann computing system has grown outdated with the rapid development of neuro-inspired computing. Memristor-based synaptic devices， which emulate biological synapses, are believed to be promising in realizing efficient neuro-inspired computing. However, previously developed memristors suffered from either high energy consumption or unstableness. Ferroelectric tunnel juncti... -
Charge-Density-Wave Induces Electronic Nematicity in Kagome ...[2022-02-21]
In a recent article published in Nature, a research team led by Prof. CHEN Xianhui, WU Tao and WANG Zhenyu from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences found the key evidence for phase transition in a kagome superconductor CsV3Sb5. At a low temperature, the team observed a transition from charge-density-wave (CDW) order t...

USTC Scientists Break Quantum Key Distribution Record Over 8...[2022-02-14]
Quantum key distribution (QKD) is presently attracting immense research interest on the global level due to its revolutionary potential to enable information-theoretically secure communication. However, the wide applications of QKD are curtailed by the channel loss since the encoded photons cannot be amplified or relayed via classical optical techniques to keep its security, which limits the incre...
