ALBUQUERQUE, N.M. - A new Department of Energy open-access quantum computing testbed is ready for the public. Scientists from Indiana University recently became the first team to begin using Sandia National Laboratories Quantum Scientific Computing Open User Testbed, or QSCOUT.
Topic: Quantum Computing
A multi-disciplinary research team has shown that radiation from natural sources in the environment can limit the performance of superconducting quantum bits, known as qubits. The discovery, reported today in the journal Nature, has implications for the construction and operation of quantum computers, an advanced form of computing that has attracted billions
Cryptography is an integral part of a cybersecurity professional’s toolkit. It is used for Confidentiality, Integrity, Non-repudiation and more. Cryptosystems are the cornerstone for securing communication, data and information systems globally and are deeply embedded in most technologies. Cryptography is integral to hordes of applications where people
Harvard researchers have developed a specialized quantum computer, known as a quantum simulator, which could be used to shed new light on a host of complex quantum processes, from the connection between quantum mechanics and material properties to investigating new phases of matter and solving complex real-world optimization problems.
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
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
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
Last year, a Long March 2D rocket took off from the Jiuquan Satellite Launch Centre in the Gobi Desert carrying a satellite called Micius, named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day. Micius is a highly sensitive
Intelligence Advanced Research Projects Activity (IARPA) has selected the University of Southern California to lead a consortium of universities and private companies to build quantum computers that are at least 10,000 times faster than the best state-of-the-art classical computers.
