Quantum mechanics. Time. Causality. Irrational. Hiding the meaning of life…
Watch a movie backwards and you'll likely get confused - but a quantum computer wouldn't. That's the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Nanyang Technological University and collaborators. In research published in Physical Review X, the international team showed that a quantum…

Controlling the uncontrollable. Giving birth to God…
Quantum bits are now easier to manipulate for devices in quantum computing, thanks to enhanced spin-orbit interaction in silicon. (1) The world was born in chaos. And chaos gave birth to us. At the end, we will manage to control everything. And everything will be destroyed. The cosmos will be lost inside the stillness of…

Quantum sounds.
Quantum physics is on the brink of many technological breakthroughs. However, the main obstacle is finding the right way to couple and precisely control a sufficient number of quantum systems (e.g. individual atoms). A team of researchers from TU Wien and Harvard University has found a new way to manipulate the quantum universe via tiny…

Stay still. Move. Logos. Silence.
Quantum mechanics is truly weird. Objects can behave like both particles and waves, and can be both here and there at the same time, defying our common sense. Such counterintuitive behaviour is typically confined to the microscopic realm and the question "why don't we see such behaviour in everyday objects?" challenges many scientists today. A…

Causality debunked.
Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyze under which conditions quantum mechanics allows the causal structure of the world to become "fuzzy." In this case, a fixed order of events is not possible. The…
