'Spooky action' to distinguish between two similar quantum devices.Byline: ANI Washington, April 28 (ANI): Physicists are using the phenomenon dubbed as 'spooky action' to distinguish between two similar quantum devices. 'Quantum ghosts' are far distant particles that can somehow 'talk' to each other, a theory put forward by famous scientist Albert Einstein, who called it 'spooky action at a distance'. Having confirmed its existence, scientists today are learning how to use this 'spooky action' as a helpful tool. Now, a team of physicists at the University of Bristol and Imperial College London History Imperial College was founded in 1907, with the merger of the City and Guilds College, the Royal School of Mines and the Royal College of Science (all of which had been founded between 1845 and 1878) with these entities continuing to exist as "constituent colleges". have harnessed this phenomenon to shed light on another unusual and previously difficult aspect of quantum physics quantum physics n. (used with a sing. verb) The branch of physics that uses quantum theory to describe and predict the properties of a physical system. quantum physics See quantum mechanics. - that of distinguishing between two similar quantum devices. In the everyday world, any process can be considered as a black box device with an input and an output. If you wish to identify the device you simply apply inputs, measure the outputs and determine what must have happened in between. But, quantum black boxes are different. Distinguishing between them is impossible using only single particle inputs because the outputs are not distinguishable: a fundamental consequence of the laws of quantum mechanics quantum mechanics: see quantum theory. quantum mechanics Branch of mathematical physics that deals with atomic and subatomic systems. It is concerned with phenomena that are so small-scale that they cannot be described in classical terms, and it is is that only very few states of a quantum particle can be reliably distinguished from one another. The Bristol-Imperial team has shown how to get around this problem using 'spooky action'. According to according to prep. 1.

In theory, such superpositions allow the computer to perform many different computations simultaneously. if they can't tell which circuits they have?" he explained. The new findings have implications for our understanding of quantum mechanics as well as the emerging potential of quantum information science Quantum information science concerns information science that depends on quantum effects in physics. It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done with quantum information. .
