Quantum Computers for Exponentially Hard Problems
A new generation of application specific quantum computers has shown great promise in solving exponentially hard problems that are inaccessible to classical computers, by employing innovative designs that do not utilize traditional gate-based architectures. The real world problems that can be treated range from issues important to industry, to the most challenging problems in cosmology. This article will explain these novel approaches being investigated at Swinburne University and elsewhere, with experiments and theory planned or underway in Australia, Japan, Europe and the USA.
First successful quantum teleportation in a computer chip
Physicists at the Swiss Federal Institute of Technology Zurich [ETH Zurich] have for the first time successfully teleported information in a solid-state system, similar to a computer chip. The major achievement of this study is that the information is not stored and processed based on the laws of classical physics, like conventional computer chips, but on those of quantum physics. The experimental device developed could serve as the basis for future…
