By IQT News posted 15 Nov 2019

(EETimes) Researchers at Nanyang Technological University in Singapore (NTU Singapore) have developed a quantum chip 1,000 times smaller than current quantum configurations. The project was led by NTU’s professor Liu Ai Qun and associate professor Kwek Leong Chuan.
Singapore Research Offers Opportunity for Quantum Cryptography in Finance
The results offer a new opportunity for implementing quantum cryptography methods in many financial systems. This new chip will improve the security context in the various communication methods, from the withdrawal of cash from the ATM to the purchase of goods online (figure 1). These are technologies that today are not very safe and whose communications can be intercepted. Only 3-4 mm wide, the chip uses quantum communication algorithms and provides a higher level of security than existing standards thanks to Quantum Key Distribution (QKD).
