Stretched photons recover lost interference

The smallest pieces of nature—individual particles like electrons, for instance—are pretty much interchangeable. An electron is an electron is an electron, regardless of whether it's stuck in a lab on Earth, bound to ...

Is your supercomputer stumped? There may be a quantum solution

Some math problems are so complicated that they can bog down even the world's most powerful supercomputers. But a wild new frontier in computing that applies the rules of the quantum realm offers a different approach.

Boosting light-based computing

University of Twente spinoff company QuiX is currently developing a photonic chip using the quantum properties of light for carrying out complex calculations. The new chip, of which a first version is already operational, ...

A faster method for multiplying very big numbers

The multiplication of integers is a problem that has kept mathematicians busy since Antiquity. The "Babylonian" method we learn at school requires us to multiply each digit of the first number by each digit of the second ...

New algorithm optimizes quantum computing problem-solving

Tohoku University researchers have developed an algorithm that enhances the ability of a Canadian-designed quantum computer to more efficiently find the best solution for complicated problems, according to a study published ...

Speeding up artificial intelligence

A group at Politecnico di Milano has developed an electronic circuit able to solve a system of linear equations in a single operation in the timescale of a few tens of nanoseconds. The performance of this new circuit is superior ...
