In October 2024, researchers at the University of Science and Technology of China reached a new frontier in quantum physics: a Schrödinger-cat state with an unprecedented coherence time of 1,400 ...

Since the realization that a linearly polarized light can create K-K’ valley coherent excitons in monolayer transition metal dichalcogenide (TMDC) semiconductors back in 2013, it has been a ...

Practical quantum computers may be another step closer to reality – and like so many technologies, we have graphene to thank for it. The bits of information in quantum computers (qubits) can famously ...

A team led by scientists from the University of New South Wales (UNSW) has announced "significantly" increasing the coherence time of a spin-orbit quantum bit (qubit) in silicon, allowing them to ...

Gaps in the coherence spectrum of diode lasers have been known to hinder research. Anselm Deninger and Thomas Renner look at how these gaps are being filled and the applications that are benefiting ...
