The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Xenon flashes for mobile devices 05.03.2013

The development of Nanyang Technological University may change the perception of the photographic abilities of mobile devices.

The camera today is an indispensable element of equipping mobile devices, but the flash, if any, is low-power, LED. Meanwhile, it is known that the quality of photographs is largely determined by the presence of light, so a powerful flash would be useful when shooting in low light conditions.

Compact and SLR cameras, as well as external flashes, use xenon lamps that can generate powerful flashes with a color temperature close to that of sunlight. It is difficult to place such a lamp in a mobile device, but it is possible, however, to power it, a large capacitor is needed that can quickly release the accumulated charge. The size of such capacitors is an almost insurmountable obstacle to xenon flashes in modern, thin smartphones and tablets.

More precisely, they were, since recently specialists from the Nanyang Technological University in Singapore created a multilayer polymer capacitor with suitable parameters. At the same time, it is four times smaller in size than a modern electrolytic capacitor of the same capacity and has a very low equivalent internal resistance.

Xenon Technologies, the world's largest manufacturer of xenon flash lamps, has become interested in commercializing the development. The parties have already entered into an appropriate agreement. They hope to have a commercial prototype by September of this year.
