In an ironic twist, physicists have shown that the very property that can be used to show that quantum computing devices can solve some problems that classical computers cannot also makes it impossible to efficiently certify ...
Logic and memory devices, such as the hard drives in computers, now use nanomagnetic mechanisms to store and manipulate information. Unlike silicon transistors, which have fundamental efficiency limitations, they require ...
