In standard quantum theory, the causal order of occurrence between events is prescribed and must be definite. This has been maintained in all conventional operation scenarios for quantum batteries, ...

A research team has developed a new technique to rapidly and accurately determine the charge state of electrons confined in semiconductor quantum dots -- fundamental components of quantum computing ...

Quantum batteries could charge more efficiently by skirting conventional rules of causality. Yuanbo Chen at the University of Tokyo and his colleagues analysed whether a particularly counterintuitive ...

HOUSTON – (Nov. 23, 2023) – True to form, a “strange metal” quantum material proved strangely quiet in recent quantum noise experiments at Rice University. Published this week in Science, the ...

Fig. 1: Schematic picture of the experimental setup showing a Chern insulator (purple) with attached electrodes (gold) and a SQUID magnetometer (shown as a loop on top of the insulator), which allows ...

In line with expectations, new quantum noise experiments conducted at Rice University revealed an unusually quiet “strange metal” quantum material. The measurements of quantum charge fluctuations, or ...

Experiments have provided the first direct evidence that electricity seems to flow through 'strange metals' in an unusual liquid-like form. True to form, a "strange metal" quantum material proved ...
