A new system developed by researchers at the University of Rochester allows them to conduct quantum simulations in a synthetic space that mimics the physical world by controlling the frequency, or color, of quantum entangled photons as time elapses. Credit: University of Rochester illustration / Michael Osadciw Scientists have made an important step toward developing computers advanced enough to simulate complex natural phenomena at the quantum level. While these types of simulations are too cumbersome or outright impossible for classical computers to handle, photonics-based quantum computing systems could provide a solution. A team of researchers from the University of Rochester’s…

Astronomers have detected high-energy neutrinos coming from within our Milky Way galaxy, potentially opening up an exciting new window of research, a new study reports. Neutrinos are extraordinarily difficult to spot, as they rarely collide with atoms. A light-year’s worth of lead would stop only about half of the neutrinos flying through it (which explains why neutrinos have been dubbed “ghost particles”). Neutrinos are created from radioactive decay, such as in nuclear reactors, or when extraordinarily high-energy particles strike atoms. The friskiest types feature energies millions to billions of times higher than those produced by the fusion reactions that power…

By U.S. Department of Energy June 29, 2023 In dense nuclear matter, quarks “line up,” becoming essentially one-dimensional. Calculations considering that single dimension plus time can track how low energy excitations ripple through nuclear matter. Credit: Brookhaven National Laboratory Scientists at Brookhaven National Laboratory have used two-dimensional condensed matter physics to understand the quark interactions in neutron stars, simplifying the study of these densest cosmic entities. This work helps to describe low-energy excitations in dense nuclear matter and could unveil new phenomena in extreme densities, propelling advancements in the study of neutron stars and comparisons with heavy-ion collisions. The Science…

Astronomers might soon get their first peek into the dark universe. On Saturday, July 1, the European Space Agency’s (ESA) Euclid spacecraft will launch on a SpaceX rocket from Florida on a mission to peer into deep space and unveil the elusive dark universe — and NASA’s James Webb Space Telescope will be an important partner in this cosmic quest. After a month-long flight, Euclid will reach a vantage point about 1 million miles (1.5 million kilometers) from Earth, where it will share its cosmic accommodation with the James Webb Space Telescope (JWST), whose powerful infrared eye probes the universe…
