Enchufados a la supremacía cuántica

Formulated by Isaac Newton 300 years ago, no one has yet been able to develop an equation that predicts the movements of three mutually orbiting bodies.

So far no theory can explain the superconductivity in the magical angle of graphene at the microscopic level, something that could change with this discovery

Physicists claim cosmic acceleration is just a local artefact, but Nobel laureate disagrees

Spin-based quantum information processing requires coherent spin manipulation. Yang et al. demonstrate coherent control of surface titanium and iron atom spins on a magnesium oxide surface with a magnetic scanning tunneling microscope tip. Arbitrary sequences of fast electrical pulses delivered to the top induced large electric fields. These fields drove metal-atom movement, which then modulated the tip-atom exchange interaction to create an oscillating effective magnetic field. Advanced spin-control protocols such as Ramsey fringes and Hahn spin echoes revealed quantum dynamics, such as coherent oscillations in a titanium atom dimer assembled on the surface with the tip.
