Analysis shows 'Super Mario Brothers' is harder than NP-hard

Completing a game of "Super Mario Brothers" can be hard—very, very hard. That's the conclusion of a new paper from researchers at MIT, the University of Ottawa, and Bard College at Simon's Rock. They show that the problem ...

Researchers demonstrate new path to reliable quantum computation

Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. Most prior work in quantum computation ...

Print your own lasers, lights and TV screens

Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have ...

Operating a computer by gesture only

Operating computers without touching them, using only hand and arm gestures: it sounds futuristic, but it's already possible. Researcher Wim Fikkert of the Centre for Telematics and Information Technology of the University ...

Quantum mechanics enables perfectly secure cloud computing

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. ...
