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 computers are computing systems that process information leveraging quantum mechanical effects. These computers rely on qubits (i.e., the quantum equivalent of bits), which can store ...

Spread the loveThe field of quantum computing has long been heralded as the frontier of technological advancement, promising unprecedented computational power. However, recent research has unveiled a ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Quantum many-body systems distribute localized information over many non-local degrees of freedom in the course of their time evolution, a process called information scrambling. Information scrambling ...

A new theoretical study involving EPFL shows how the noise in today’s quantum computers limits how much work their circuits can really do, and how this affects training and simulation.
