Researchers create quantum chip 1,000 times smaller than current setups
New quantum communication chip is 1000 times smaller than modern quantum devices, but works just as efficiently.
Most current security standards for communication systems used at ATMs or online shopping do not use quantum technology. Therefore, there is currently a threat of interception of a PIN or password during electronic data transmission..
Researchers from Nanyang Technological University developed a chip less than 4 mm long that uses quantum communication algorithms to improve transaction security. It does this by integrating passwords into the transmitted information to create a secure quantum key. After receiving the data, they are destroyed along with the key, which further increases the reliability of such a connection..
The system uses randomized lines of code to encrypt information, which can only be accessed by the recipient with the correct key. This simplifies communication as there is no need to transfer additional passwords or biometric data.
The developers claim that the use of such chips will be cost effective as they are made from readily available materials such as silicon. The invention can also stimulate the development of next generation communication devices and improve digital services such as online banking, digital government.
Earlier, European researchers presented another version of the chip to protect information systems, which generates random numbers by firing a tiny laser at one of two targets.
