It is called quantum communication and according to the publication MIT Review Technology, transferring data in this state promises to minimize hacking: “Quantum communication takes advantage of the laws of quantum physics to protect data. These laws allow particles, usually photons of light that transmit data through optical cables, to have a state of superposition in which they can simultaneously adopt a state of zero and one, a phenomenon known as quantum superposition. These particles are known as quantum bits, or qubits. »
Today, the data of our communications is encrypted to be sent later via optical fiber with the keys necessary to decrypt them. Experienced hackers can intercept these communications and decrypt them without even leaving a trace. This is why, for decades, governments and companies have been working on the development of quantum communication which could guarantee the exchange of information in a more secure way.
Chinese scientist, Long Guilu who has devoted more than two decades to the development of direct quantum communication technology, announced that he has successfully transmitted data more than 100 kilometers away, setting a new record; the previous record was 18.5 kilometers. Although the data transmission is currently slow (0.54 bits per second), the results are encouraging. Guilu, a professor of physics at Tsinghua University, says his technology is ready to be integrated with current encryption techniques and that could mean a revolution in the way information is shared.
The test results were published in detail by Nature.com and in a statement, Guilu commented, “If we replace the parts of the internet where the most eavesdropping attacks occur with quantum channels today , they will have the added ability to detect and prevent eavesdropping, making communications even safer.
