“New concepts for quantum computer implementations, algorithms, and advances in the theoretical understanding of the physics requirements for quantum computers appear almost weekly in the scientific literature.”

ARDA, Report of the Quantum Information Science and Technology Experts Panel

"Many crypto-systems considered robust have been broken after a certain amount of time (between 10-20 years).  ... We need to build crypto-systems that offer long term security, for example for protecting financial and medical information (medical information such as our DNA may be sensitive information with impact on our children, our grandchildren and beyond)."

“The rapidly evolving field of quantum computers is one of the most active research areas of modern science, attracting substantial funding that supports research groups at internationally leading academic institutions, national laboratories, and major industrial-research centers.”
