Scientists have successfully achieved a quantum collective behavior of macroscopic mechanical oscillators, unlocking new possibilities in quantum technology.

Quantum technologies are radically transforming our understanding of the universe. One emerging technology are macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the quantum realm, macroscopic oscillators could enable ultra-sensitive sensors and components for quantum computing, opening new possibilities for innovation in various industries.

Controlling mechanical oscillators at the quantum level is essential for developing future technologies in quantum computing and ultra-precise sensing...

Quantum Breakthrough when Light makes Materials Magnetic

The laser light is circularly polarized. Image created by AI
The laser light is circularly polarized, i.e. the light has the shape of a “corkscrew”. When laser light with this type of polarization enters a material, it transfers its circular polarization to the atoms in it, by making them rotate and generate atomic currents. If the frequency of the light matches the frequency of vibration of the atoms, the effect is enhanced and a relatively large magnetism is generated. (AI generated image by Alexander Balatsky)

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

Quantum Technology could make Charging Electric Cars as Fast as Pumping Gas

A pictorial illustration of today’s electric vehicle versus the future vehicle based on quantum battery technologies. Employing quantum charging would lead to a 200 times speedup in a typical EV, which means that the charging time would be cut from 10 hours to about 3 minutes (at home), or 30 minutes to 9 seconds at a charging station.

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...
