Optimized quantum algorithms present solution to Fermi-Hubbard model on near-term hardware. Researchers from the University of Bristol and quantum start-up, Phasecraft, have advanced quantum computing research, bringing practical hybrid quantum-classical computing one step closer. The team, led by Bristol researcher and Phasecraft co-founder, Dr. Ashley Montanaro, has discovered algorithms and analysis which significantly lessen […]

The Google Quantum Computer. Credit: Eric Lucero/Google, Inc. Researchers led by City College of New York physicist Pouyan Ghaemi report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers. Their paper, entitled “Creating and Manipulating a Laughlin-Type ν=1/3 Fractional […]

Complex interlocking components mean no tools are needed. Credit: © Larsson et al. An interactive system to design and fabricate structurally sound wood joints. Wood is considered an attractive construction material for both aesthetic and environmental purposes. Construction of useful wood objects requires complicated structures and ways to connect components […]

Animation Study led by a University of Oregon physicist reconfigures a distance-calculation technique built around empirical observations. Using known distances of 50 galaxies from Earth to refine calculations in Hubble’s constant, a research team led by a University of Oregon astronomer estimates the age of the universe at 12.6 billion […]

PNNL quantum algorithm theorist and developer Nathan Wiebe is applying ideas from data science and gaming hacks to quantum computing. Everyone working on quantum computers knows the devices are error prone. The basic unit of quantum programming – the quantum gate – fails about once every hundred operations. And that error […]

Algorithm Quickly Simulates a Roll of Loaded Dice The fast and efficient generation of random numbers has long been an important challenge. For centuries, games of chance have relied on the roll of a die, the flip of a coin, or the shuffling of cards to bring some randomness into […]

A new MIT-developed search-and-rescue algorithm identifies hidden “traps” in ocean waters. The method may help quickly identify regions where objects — and missing people — may have converged.
