Quantum technology is a growing field of physics and engineering which utilizes properties of quantum mechanics as a basis for advanced practical applications such as quantum computing, sensors, information, communication and medicine. This promises to lead to a new era of technology unlike anything we’ve known. Computers will be much more powerful, medical treatment will be non-invasive and far safer than today, and even teleportation can be envisioned. A phenomenon that stands at the core of this development is the Quantum phase transition.
