Oak Ridge National Laboratory scientists demonstrated that an electron microscope can be used to selectively remove carbon atoms from graphene ’s atomically thin lattice and stitch transition-metal dopant atoms in their place.

This method could open the door to making quantum building blocks that can interact to produce exotic electronic, magnetic and topological properties.

This is the first precision positioning of transition-metal dopants in graphene. The produced graphene-dopant complexes can exhibit atomic-like behavior, inducing desired properties in the graphene.

Causality is one of those difficult scientific topics that can easily stray into the realm of philosophy.

California researchers discovered a way to leverage an unused property of light to apply the unrestricted nature of the quantum domain to wireless communication, creating a new type of channel with infinite capacity that could make looming data limitations irrelevant.

Now cosmology inches towards the next paradigm shift: One of the most mind-boggling discoveries of modernity is that the fabric of spacetime is emergent from something beneath it. “[O]ne new theory says that Dark Matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain Dark Matter,” in the words of Michio Kaku as an opening quote to this article. #DarkMatter #DarkEnergy #QuantumGravity #ComputationalPhysics #MTheory #DTheoryofTime #OmegaSingularity #pancomputationalism #multiverse #ontology

Dark Matter could be ordinary matter in the “probabilistic space” and “phase space” (5th and 6th dimensions of M-theory), possibly with “dark star systems” and life, imperceptible to us at our current level of development. In turn, Dark Energy could be a.

O.,.o Could make a semi renewable fusion reactor or propulsion system.

Atoms of antihydrogen are affected by the Lamb shift, which results from transient particles appearing and disappearing.

A team of researchers at Universität Stuttgart has developed an ion-optics-based quantum microscope that is capable of creating images of individual atoms. In their paper published in the journal Physical Review Letters, the group explains how they built their microscope and how well it worked when tested.

Using a method called quantum annealing, D-Wave’s researchers demonstrated that a quantum computational advantage could be achieved over classical means.

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.

MIT researchers using superconducting quantum bits connected to a microwave transmission line have shown how the qubits can generate on demand the photons, or particles of light, necessary for communication between quantum processors.
