Antiferromagnetically ordered particles are represented by red and blue spheres in this artist’s impression. The particles are in an array of optical traps. Credit: Chen Lei Topics: Applied Physics, Computer Science, Quantum Computer, Quantum Mechanics Experiments on the Fermi–Hubbard model can now be made much larger, more uniform, and more quantitative. A universal quantum computer—capableContinue reading “FHM…”
‘Teleporting’ Images…
High-dimensional quantum transport enabled by nonlinear detection. In our concept, information is encoded on a coherent source and overlapped with a single photon from an entangled pair in a nonlinear crystal for up-conversion by sum frequency generation, the latter acting as a nonlinear spatial mode detector. The bright source is necessary to achieve the efficiencyContinue reading “‘Teleporting’ Images…”
Quantum Switch…
Credit: CC0 Public Domain Topics: Condensed Matter Physics, Materials Science, Quantum Computer, Quantum Mechanics Quantum scientists have discovered a rare phenomenon that could hold the key to creating a ‘perfect switch’ in quantum devices, which flips between being an insulator and a superconductor. The research, led by the University of Bristol and published in Science, found theseContinue reading “Quantum Switch…”
Quantum Slow Down…
Topics: Chemistry, Computer Science, Quantum Computer, Quantum Mechanics Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times. Joint lead researcher and Ph.D. student Vanessa Olaya Agudelo said,Continue reading “Quantum Slow Down…”

Quipu…
Topics: Lasers, Modern Physics, Quantum Computer, Quantum Mechanics Physicists have devised a mind-bending error-correction technique that could dramatically boost the performance of quantum computers. When the ancient Incas wanted to archive tax and census records, they used a device made up of a number of strings called a quipu, which encoded the data in knots. Fast-forwardContinue reading “Quipu…”
Breaking Physics…
Topics: Quantum Computer, Quantum Mechanics, Thermodynamics In what could prove to be a momentous accomplishment for fundamental physics and quantum physics, scientists say they’ve finally figured out how to manufacture a scientific oddity called a time crystal. Time crystals harness a quirk of physics in which they remain ever-changing yet dynamically stable. In other words,Continue reading “Breaking Physics…”
Space-Based Quantum Technology…
Topics: Computer Science, Quantum Computer, Quantum Mechanics Quantum technologies are already revolutionizing life on Earth. But they also have the potential to change the way we operate in space. With the U.S., China, and Europe all investing heavily in this area, these changes are likely to be with us sooner rather than later. So howContinue reading “Space-Based Quantum Technology…”
