Schrödinger's cat with 20 qubits

Dead or alive, left-spinning or right-spinning—in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, including researchers from ...

New toolkit for photonics: Quantum simulation by light radio

Intensive research is being carried out on quantum simulators: they promise to precisely calculate the properties of complex quantum systems, when conventional and even supercomputers fail. In a cooperative project, theorists ...

Leiden physicists image lumpy superconductor

High-temperature superconductivity is one of the big mysteries in physics. Milan Allan's research group used a Josephson Scanning Tunneling Microscope to image spatial variations of superconducting particles for the first ...

Solving problems on a quantum chessboard

Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate ...

Targeting individual atoms

Nuclear magnetic resonance (NMR) spectroscopy is one of the most important methods of physicochemical analysis. It can be used to determine precise molecular structures and dynamics. The importance of this method is also ...

Hypersonic matterwaves for ultrafast atomtronics

Atomtronics manipulates atoms much in the way that electronics manipulates electrons. It carries the promise of highly compact quantum devices which can measure incredibly small forces or tiny rotations. Such devices might ...

Manipulating atoms one at a time with an electron beam

The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control.
