The Wallenberg Centre for Quantum Technology (WACQT), based at Chalmers University in Sweden is receiving an increase in funding from the Knut and Alice Wallenberg Foundation to 80 million Swedish Krona (SEK) per year from […]
The U.S. Department of Energy’s (DOE) Sandia National Laboratory has deployed a new trapped ion quantum computer capability, called QSCOUT (Quantum Scientific Computing Open User Testbed) for free use to qualified researchers. The current system […]
Quantum 5, 412 (2021). https://doi.org/10.22331/q-2021-03-15-412 We consider the task of breaking down a quantum computation given as an isometry into C-NOTs and single-qubit gates, while keeping the number of C-NOT gates small. Although several decompositions […]
ColdQuanta, the leader in Cold Atom Quantum Technology, today announced Dan Caruso as its Executive Chairman and interim CEO, according to a press release. Caruso will be stepping in for Bo Ewald, ColdQuanta’s CEO and a pioneer […]
Quantum 5, 411 (2021). https://doi.org/10.22331/q-2021-03-15-411 Passivity is a fundamental concept that constitutes a necessary condition for any quantum system to attain thermodynamic equilibrium, and for a notion of temperature to emerge. While extensive work has […]
Mona Lisa’s smile. Mary Lou Retton’s Olympic vault. Mariah Carey’s musical pitch. All are considered perfect. So are the numbers 6 and 28. With feats of artistry and athleticism, perfection lies in the eye of […]
Quantum 5, 410 (2021). https://doi.org/10.22331/q-2021-03-15-410 Tensor networks represent the state-of-the-art in computational methods across many disciplines, including the classical simulation of quantum many-body systems and quantum circuits. Several applications of current interest give rise to […]
The U.S. Department of Energy (DOE) recently announced plans to provide $30 million for Quantum Information Science (QIS) research that helps scientists understand how nature works on an extremely small scale—100,000 times smaller than the […]
The race to build the first practical quantum computers looks like a two-horse contest between machines built from superconducting qubits and those that use trapped ions. But new research suggests a third contender—machines based on […]
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, […]
