Experimental realization and self-testing of semisymmetric informationally complete measurements via a one-dimensional photonic quantum walk
Xu Xu, Han-Yu Cheng, Meng-Yun Ma +7
Generalized quantum measurements play a crucial role in quantum mechanics, and symmetric informationally complete positive operator-valued measurements (SIC POVMs) provide a powerf…

The role of electron interactions in a failed insulator revealed by shot noise
Mateusz Szurek, Hanqiao Cheng, Zilu Pang +2
In materials known as failed insulators, electrical resistivity increases as temperature decreases, yet does not diverge - a phenomenon inconsistent with single-particle theories.…

Anomalous shot noise in a bad metal beta-tantalum
M. Szurek, H. Cheng, Z. Pang +3
We investigate the electronic shot noise produced by nanowires of -Ta, an archetypal ``bad" metal with resistivity near the Ioffe-Regel localization limit. The Fano factor char…
