Simulations predict existence of radio wave hotspots in black holes

Some of the synthetic images produced by the researchers show the hotspots spinning as an observer spins around the black hole’s spin axis. Credit: Crinquand et al Black holes, regions of spacetime where gravity is so strong that nothing can escape, are among the most fascinating and studied cosmic phenomena. Although there are now countless …

Simulations using a quantum computer show the current limits of the technology

November 14, 2022• Physics 15, 175 Quantum circuits still cannot outperform classical circuits when simulating molecules. E.Lucero/Google Be real. The Google-made Sycamore chip, comprising 53 quantum bits, was used to explore the “quantum advantage”: performance in quantum computing that exceeds anything possible on classical computers. But how well does this type of device perform in …
