Researchers Develop A New Alphabet to Write and Read Quantum Messages With Very Fast Particles

By IQT News posted 11 Sep 2019

(ScienceDaily) Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails. Thanks to a new method to write and read the message researchers guarantee the reliable decoding of quantum messages which are transmitted extremely fast.
Researchers at the University of Vienna and the Austrian Academy of Sciences have announced a new method to read and write the message in a manner that guarantees the reliable decoding of quantum messages which are transmitted extremely fast. The result published in the journal PRL opens up new possibilities of technological applications in quantum information and quantum communication.
“These results are indicative that this translation procedure could open up to new applications in relativistic quantum information,” says Flaminia Giacomini, the lead author of the paper. For instance, this technique could be helpful in satellite-based quantum communication, where a particle carrying a message has to travel quickly between two far-away points.
