An aspect of quantum theory called contextuality is crucial for achieving universal quantum computation, a University of Waterloo Institute of Quantum Computing news release reported.
Quantum devices are almost impossible to build because they need to operate in a noise-resistant environment. The "magic" is a new approach to building a noise-resistant quantum computer. The process is known as magic-state distillation.
By identifying this "magic" state researchers could be closer to achieving a universal quantum computer.
... In the real world measurements look at the property of something but in quantum terms what is observed really depends on how the process is carried out. Measurement outcomes rely on all of the other measurements that are performed.
"Contextuality means that quantum measurements can not be thought of as simply revealing some pre-existing properties of the system under study. That's part of the weirdness of quantum mechanics,"
