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 ...

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 ...

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, ...

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 ...

A new type of quantum computing called boson sampling is capable of calculations that no classical computer could accomplish in any reasonable amount of time. This is the second time this feat, known ...

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 ...

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 ...

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 ...
