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…”
Smallest Qubit Computer…
Topics: Computer Science, Quantum Computer, Quantum Mechanics The smallest quantum computer to date has been claimed by a team of researchers in Austria, Switzerland, and Germany. Using strings of trapped ions that are addressed using laser pulses, Ivan Pogorelov at the University of Innsbruck and colleagues created a system that contains 24 fully-entangled quantum bits (qubits) andContinue reading “Smallest Qubit Computer…”
Graphene Beam Splitter…
Topics: Graphene, Interferometry, Nanotechnology, Quantum Computer A graphene-based “beam splitter” for electronic currents has been built by researchers in France, South Korea, and Japan. Created by Preden Roulleau at the University of Paris and colleagues, the tunable device’s operation is directly comparable that of an optical interferometer. The technology could soon enable allow electron interferometry to beContinue reading “Graphene Beam Splitter…”
Integrated Nanodiamonds…
Topics: Nanotechnology, Quantum Computer, Quantum Mechanics, Semiconductor Technology (Nanowerk News) Physicists at Münster University have succeeded in fully integrating nanodiamonds into nanophotonic circuits and at the same time addressing several of these nanodiamonds optically. The study creates the basis for future applications in the field of quantum sensing schemes or quantum information processors. The resultsContinue reading “Integrated Nanodiamonds…”
Quantum Modem…
Topics: Modern Physics, Nanotechnology, Quantum Computer, Quantum Mechanics (Nanowerk News) The first quantum revolution brought about semiconductor electronics, the laser and finally the internet. The coming, second quantum revolution promises spy-proof communication, extremely precise quantum sensors and quantum computers for previously unsolvable computing tasks. But this revolution is still in its infancy. A central researchContinue reading “Quantum Modem…”
City-Sized, Secure Quantum Network…
Topics: Cryptography, Futurism, Internet of Things, Modern Physics, Quantum Computer, Quantum Mechanics Quantum cryptography promises a future in which computers communicate with one another over ultrasecure links using the razzle-dazzle of quantum physics. But scaling up the breakthroughs in research labs to networks with a large number of nodes has proved difficult. Now an international teamContinue reading “City-Sized, Secure Quantum Network…”
