NTU Singapore researchers develop quantum communication chip 1,000 times smaller than current setups
The tiny chip offers the same superior security that quantum technology is known for
Researchers at Nanyang Technological University, Singapore (NTU Singapore) have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, without compromising the superior quality that quantum technology is known for.
Led by NTU Professor Liu Ai Qun, and Associate Professor Kwek Leong Chuan, the team’s findings were published in Nature Photonics.
The tiny chip uses quantum communication algorithms to provide enhanced security compared to existing standards. It does this by integrating passwords within the information that is being delivered, forming a secure ‘quantum key’. After the information is received, it is destroyed along with the key, making it an extremely secure form of communication.
The chip opens doors for more secure communication technologies that can be deployed in compact devices such as smartphones, tablets and smart watches. It also lays the foundation for better encryption methods for online transactions and electronic communication.
