Quantum computers promise to run calculations far beyond the reach of any conventional supercomputer. They might revolutionize the discovery of new materials by making it possible to simulate the behavior of matter down to the atomic level. Or they could upend cryptography and security by cracking otherwise invincible codes. There is even hope they will

In recent years, there has been a substantial amount of research on quantum computers - machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum computers are ever built, they will compromise the security of many commonly used cryptographic
Cloud quantum computing has been used to calculate the binding energy of the deuterium nucleus – the first-ever such calculation done using quantum processors at remote locations. Nuclear physicists led by Eugene Dumitrescu at Oak Ridge National Laboratory in the US used publicly available software to achieve the remote operation of two distant quantum
Over the past few decades, topology - a branch of mathematics dealing with shapes that can be turned into other shapes by processes like bending and stretching - has evolved from an arcane pursuit into an increasingly powerful tool for analyzing the real world. The role of symmetry in the topological world has turned out to be particularly important.
The U.S. Department of Energy (DOE) is joining the quest to develop quantum computers, devices that would exploit quantum mechanics to crack problems that overwhelm conventional computers. The initiative comes as Google and other companies race to build a quantum computer that can demonstrate "quantum supremacy" by beating classical computers on a test
The most recent one comes from Microsoft, which has unveiled Q# (pronounced Q sharp) and some associated tools to help developers use it to create software. It joins a growing list of other high-level quantum programming languages such as QCL and Quipper. But given that practically nobody has a quantum computer, what's the point?
Microsoft is offering a developer kit to help get started in quantum computing and using the company's quantum-focused Q# programming language.
Research teams headed by Professors Wolfgang Wernsdorfer and Mario Ruben of KIT, together with scientists of the Institut Neel (Grenoble), have succeeded in applying Grover's algorithm to a molecular magnet and, thus, created a quantum system, whose task is the rapid finding of search elements in unsorted data.

Who said light only had to travel in boring waves or particles? Not Harvard. Its researchers have found a way to spin light into complex states that promise breakthroughs in multiple fields. They've built metasurfaces whose elaborate optics combine two kinds of light momentum (orbital angular and spin angular) to send light into corkscrews, spirals or even

Physicists sometimes say that a beam of light traveling through space is like a "great smoky dragon." One can know much about where the light comes from (the dragon's tail) and where it is seen (the dragon's head), yet still know precious little about the journey in between (the dragon's mysterious, nebulous body). As light travels from source to detection,
