Researchers from the known to the Green continent Australian National University (abbr. – ANU) and not so far away and the University of Otago, which is New Zealand, have created a quantum hard drive (so far as a prototype), which may significantly change the scope of secure data encryption. Using rare earth europium atoms included in the yttrium-ortosilikatnye crystals (YSO), scientists have destroyed the previous assumptions about the information about the quantum, creating a data storage device capable of retaining data on the quantum state for up to 6 hours at a time. The very concept of a quantum encryption process already offers the option of secure electronic exchange of information in a relatively short distances (up to about 100 km or about about 62 miles). However, this latest study process can help to create an international allow encrypted quantum communication system, providing unprecedented opportunities for conservation and effectively eliminating instability problems faced by users when using currently available technology.
“We believe that soon it will be possible to distribute information about the slice between any two places on the globe,” said Zhong Mantszin, a researcher on the project from the School of Physics ANU Research and Development (abbr. – RSPE). “Quantum states are fragile and often break down in a matter of milliseconds. In our experiments in the storage process has the potential to radically change the process of transferring quantum information. “In contrast to conventional electronic communication networks, where a transmission signal can be increased amplifiers are strategically located from time to time along the entire length of its passage way, information about slice quantum requires “memory” in the form of question based on qubits (“quantum bits”) are a storage node, and each connected with the next in a series of continuous separate optical paths.
Unfortunately, this sophisticated method is necessary, because, at best, an attempt to strengthen based on quantum information to add extra “noise” to her, and in the worst case, simply destroy its quantum state. As a result, network communications quantum encrypted data in our time include a large number of “chained” to each other memory units, long-term stability and reliability which until very, very doubtful.
