The quest to build an unhackable quantum Internet

Quantum technologies have the ability to create unbreakable codes. Blockchain technologies ensure authenticity and transparency in record keeping. They are critical to Singapore's $25 billion research plans for the next five years to create new economic opportunities for the nation in a post-Covid-19 world. The Straits Times looks into the potential uses of quantum technology and blockchain.
