A new theoretical study has taken a close look at how noise influences these circuits. The results show that noise places a ...

Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Taking quantum circuits from a vague academic notion to the factory floor in just over 40 years might sound daunting — even impossible. But as Yale physicist Robert Schoelkopf explains, it all came ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...
