A new type of machine could rival quantum computers in exceeding the power of classical computers, researchers say. Quantum computers rely on the bizarre properties of atoms and the other construction ...

Atoms in an optical lattice perform a "quantum walk" where they experience many different quantum phenomena, such as superposition or tunneling as they move around the lattice. Credit: Alex Downham, ...

Chinese researchers performed Gaussian boson sampling by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random ...

In their simulated system, image data is first simplified using a process called principal component analysis (PCA), which reduces the amount of information while preserving key features. A complex ...

In what has been hailed as a computing milestone, a team of researchers from the University of Science and Technology of China has achieved quantum supremacy thanks to a device that can manipulate ...

A similar problem has been solved for photons in an optical network using the Boson sampling method mentioned in the first paragraph. A waveguide network used for Boson sampling is shown schematically ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range ...

In daily life, when two objects are “indistinguishable,” it’s due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ...
