CAMBRIDGE, MA — The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic ...

For example, Shor’s factoring algorithm can be viewed as an algorithm that finds the order of an element in a black-box group. Some directions in which future progress might be made are listed below. ...

The team implemented the 'phase estimation algorithm' — a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It lies at the heart of quantum computing and ...
