As it happens, a lot of the hardest problems organizations face today involve making sense of complex systems of interconnected yet uncertain events, often in the form of mathematical models that cannot generally be solved. Finland is also a part of the European Quantum Communication Network, which aims to develop and ensure a secure infrastructure for the needs of communication in the quantum age. Continue reading with a Scientific American subscription. Adding a single qubit doubles the scale of computation that's possible. If it happens, it would be a paradigm shift in the world of trading that would allow those with access to such a computer to make unparalleled amounts of money.
