In 2014, researchers at [[University of New South Wales]] used silicon as a protectant shell around [[qubit]]s, making them more accurate, increasing the length of time they will hold information and possibly made quantum computers easier to build.<ref>{{cite journal |url=http://www.computerworld.com/article/2837813/researchers-use-silicon-to-push-quantum-computing-toward-reality.html |title=Researchers use silicon to push quantum computing toward reality |journal=Computer World |date=23 October 2014 |first=Sharon |last=Gaudin}}</ref>

In April 2015 IBM scientists claimed two critical advances towards the realization of a practical quantum computer. They claimed the ability to detect and measure both kinds of quantum errors simultaneously, as well as a new, square quantum bit circuit design that could scale to larger dimensions. <ref>[http://www-03.ibm.com/press/us/en/pressrelease/46725.wss IBM Scientists Achieve Critical Steps to Building First Practical Quantum Computer]</ref>
