Cambridge Quantum Computing (CQCL) announces the development of t|ket> a unique quantum computing operating system. A quantum computer takes advantage of quantum interference creating an immense advantage in computational speed over conventional computers. It has significant applications for the global economy, including financial markets, insurance, intelligence, cyber-security, internet, medicinal and pharmaceutical research, defence, energy, database management, logistics and communications. CQCL is at the forefront of developing an operating system that will allow users to harness the joint power of classical super computers alongside quantum computers.”]
