Blick, Yuxuan Jiang, and Elke Scheer Micro- and nanomechanical resonators exhibit extreme sensitivity, but are also vulnerable to external noise — a way to squeeze the output of nonlinear resonators improves detector performance.

Author(s): Siwei Xue, Maoyuan Wang, Yong Li, Shuyuan Zhang, Xun Jia, Jianhui Zhou, Youguo Shi, Xuetao Zhu, Yugui Yao, and Jiandong Guo Nodal-line semimetals (NLSMs), a large family of new topological phases of matter with continuous linear band crossing points in the momentum space, attract considerable attention. Here, we report the direct observation of plasmons originating from topological nodal-line states in a prototypical NLS... [Phys...

Author(s): Yulin Wu et al. Two experimental quantum computers tackle the most complex problems yet, suggesting an end to the debate on whether quantum “primacy”—the point at which a quantum computer outperforms the best possible classical computer—can be reached.
