Hacker attacks on everything from social media accounts to government files could be largely prevented by the advent of quantum communication, which would use particles of light called “photons” to secure information rather than a crackable code.
The problem is that quantum communication is currently limited by how much information single photons can help send securely, called a “secret bit rate.” Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second.
“Increasing the bit rate allows us to use single photons for sending not just a sentence a second, but rather a relatively large piece of information with extreme security, like a megabyte-sized file,” said Simeon Bogdanov, a Purdue postdoctoral researcher in electrical and computer engineering.
