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, […]
Researchers at the International Centre for Theoretical Physics (ICTP) in Italy and the PICO group at Aalto University in Finland have introduced the idea of an information demon that follows a customary gambling strategy to […]
