A team of scientists from the University of Ottawa in Canada came up with a solution against illegal cyber attacks and hacking. They found out how to protect quantum computing networks from hackers by developing the first high-dimensional quantum cloning device.
Thus, the Canadian researchers created the quantum twining appliance that they can use to break a secure message. After this, they can extract information and find clues on how to protect quantum computing technologies from cyber assaults.
In quantum technology, each bit of information is split into multiple conditions ahead of zero and one. Thus, it is much more vulnerable to cyber hackings. Also, these attacks become more intense every year as hackers become more specialized and create threats which are more difficult to handle.
However, the discovery of this new cloning machine, administrators would be able to offer a better defense of their quantum devices against external threats and attacks.
Ebrahim Karimi is a professor at the University of Ottawa and one of the main researchers in the project. He is confident about their new discovery. He said that their machine was the first ever high-dimensional quantum cloning device that could successfully break a protected quantum message. After they decode all messages, they would have all the clues necessary for the accurate protection of the networks.
The extensive version of the study is published in the journal Science Advances. There, the scientists have also explained how typical computing systems work, by using bits of information containing zeroes and ones. These systems are prone to hacking. They also explained the more advanced system of quantum computing, where information uses more states apart from zero and one.
Hackers who attack traditional computing systems merely have to copy and paste information to create the same form as the original one. Quantum systems are supposed to be safer, since they transmit data in a more secure manner. If one tries to duplicate quantum information, he would obtain an altered information which perfectly serves the purpose of hacking.
However, the Ottawa researchers have succeeded in decoding the way in which quantum information is transmitted. They used the cloning device to replicate the ‘qudits’, namely the photons that reproduce the information.
Their discovery would allow them to analyze the quantum communication systems and see how information in transmitted in these networks.
