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,
Just when it was looking like the underdog, classical computing is striking back. IBM has come up with a way to simulate quantum computers that have 56 quantum bits, or qubits, on a non-quantum supercomputer - a task previously thought to be impossible. The feat moves the goalposts in the fight for quantum supremacy, the effort to outstrip classical
That broad charter has ended up putting Microsoft on the path to building the first topological qubit, a robust type of quantum bit that Microsoft believes will serve as the basis for a scalable, general purpose quantum computer system – and mark a profound breakthrough in the field of quantum physics.
The 4th International Conference on Quantum Technologies held in Moscow last month was supposed to put the spotlight on Google, who were preparing to give a lecture on a 49-qubit quantum computer they have in the works. A morning talk presented by Harvard University's Mikhail Lukin, however, upstaged that evening's event with a small announcement of his
Quantum-based networks have been proposed as the next innovation for both speeding up and sending more information through communications networks-to that end, teams in countries such as Japan, the U.S. and China have been working hard to better understand how to actually create them. Most in the field agree that national, international and global quantum
For the first time, physicists have demonstrated that clients who possess only classical computers-and no quantum devices-can outsource computing tasks to quantum servers that perform blind quantum computing. "Blind" means the quantum servers do not have full information about the tasks they are computing, which ensures that the clients' computing tasks are
