An international team of researchers (Japan, USA – University of Pittsburgh) used very short laser pulses to excite electrons inside a silicon crystal creating coherent vibrations of the silicon structure, such that the motions of the electron and the silicon atoms became entangled. The state of the system was then probed after a variable delay time with a second laser pulse. Based on their theoretical model, the scientists were able to explain oscillations observed in the charge generated as a function of delay time. The research may lead to quantum computers based on existing silicon devices that can rapidly perform tasks out of the reach of even the fastest supercomputers now available…read more.
