The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories...

Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable, considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. Much research has been pursued in order to develop alternative sources of energy, most of which use electricity as the main energy carrier...

The conductivity of living organs, such as the heart, could be imaged non-invasively using quantum technology, which has the potential to revolutionize the diagnosis and treatment of atrial fibrillation. Atrial fibrillation (AF) is a heart condition that causes an irregular and abnormally fast heart rate, potentially leading to blood clots, stroke, heart failure and other heart-related complications. While the causes of AF are unknown, it affects around one million people in the UK with cases predicted to rise at a great cost to the NHS.

Currently, AF is commonly diagnosed using an electrocardiogram (ECG), but this can only be done during an episode, so complementary means of diagnosis are needed.

AF is treated thr...

The ‘just right’ structure that emerges when you drive a system containing light and matter (like the universe), neither too fast nor too slow across a quantum phase transition. It illustrates the findings of the study titled “Enhanced dynamic light-matter entanglement from driving neither too fast nor too slow,” published in the journal Physical Review. Credit: Oscar Acevedo, Universidad de los Andes, and Neil Johnson, University of Miami. The study is a collaboration between the Universidad de los Andes in Colombia and the University of Miami.

By studying a system that couples matter and light together, like the universe, researchers have found crossing a quantum phase transition at intermediate speeds generates the richest, most complex structure...
