nsane.forums Posted March 10, 2010 Share Posted March 10, 2010 It feels like quantum computers have barely been invented, and scientists are already testing how extensible the current technology is. A paper published in Nature Photonics this week describes how researchers are beginning to push the bandwidth limits of quantum memory. Using photon pulses and cesium vapor has provided bandwidths on par with broadband connections, rates 100 times those of other quantum memory systems currently being tested. However, the system's efficiency is still very low, and advances will have to be made in other fields before it can be improved.Since many quantum computing implementations operate on photons, a quantum memory that doesn’t involve converting photons into other media, like electrical pulses, would be ideal. Unfortunately, current photon-based media suffers from problems with storage time, retrieval efficiency, and bandwidth. The paper tackles the last issue, as current quantum systems are limited to a data rate of a few megahertz at most. View: Original Article Link to comment Share on other sites More sharing options...
