Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon.
The team used microwave energy to align two electron particles suspended in silicon, then used them to perform a set of test calculations.
By using silicon, the scientists hope that quantum computers will be more easy to control and manufacture.
Zoom in close on the center of the picture above, and you can spot something you perhaps never thought you’d be able to see: a single atom. Here is a close-up if, you’re having trouble:
This strontium atom is emitting light after being excited by a laser, and it’s the winner of the UK’s Engineering and Physical Sciences Research Council (EPSRC) photography award. The EPSRC announced the winners of its fifth annual contest yesterday. Winning photographer David Nadlinger, graduate student at the University of Oxford, was just excited to be able to show off his research.
“It’s exciting to find a picture that resonates with other people that shows what I spend my days and nights working on,” Nadlinger told me. The best part, to him, was “the opportunity to excite people about my research, more than winning a competition.”
Display of a candidate event for a W boson decaying into one muon and one neutrino from proton-proton collisions recorded by ATLAS with LHC stable beams at a collision energy of 7 TeV. (Image: CERN In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. The reported result gives a value of 80370±19 MeV for th…
Spin a merry-go-round fast enough and the riders fly off in all directions. But the spinning particles in a Rice University lab do just the opposite.
Experiments in the Rice lab of chemical engineer Sibani Lisa Biswal show micron-sized spheres coming together under the influence of a rapidly spinning magnetic field. That’s no surprise because the particles themselves are magnetized.
But how they come together is of interest as the particles first gather into a disorganized aggregated cluster and then into a crystal-like regimen as the magnetic field becomes stronger.
By building the most general framework for the n-particle Hardy’s paradox and Hardy’s inequality, the results of the new paper provide a stronger Hardy’s paradox, and can also detect more quantum entangled states. As the success probability for the three-qubit generalized Hardy’s paradox reaches 0.25, the researchers are very hopeful that it will be observed in future experiments. Credit: Jiang, et al. © 2018 American Physical Society In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6–9%) of observing a particle and its antiparticle in…
