Physicists demonstrate the quantum von Neumann architecture, a quantum processor, and a quantum memory on a chip

UCSB physicists have demonstrated a quantum integrated circuit that implements the quantum von Neumann architecture. In this architecture, a long-lived quantum random access memory can be programmed using a quantum central processing unit, all constructed on a single chip, providing the key components for a quantum version of a classical computer.

Digital quantum simulator realized

The physicists of the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck have come considerably closer to their goal to investigate complex phenomena in a model system: They have realized a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently.

Physicists capture microscopic origins of thinning and thickening fluids

In things thick and thin: Cornell physicists explain how fluids -- such as paint or paste -- behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear -- a specific way of stirring.

Superconductivity-related materials retain shape but change properties under strain

A University of Arkansas physicist and his colleagues have found that ultra-thin films of superconductors and related materials don't lose their fundamental properties when built under strain when built as atomically thin layers, an important step towards achieving artificially designed room temperature superconductivity. This ability will allow researchers to create new types of materials and properties and enable exotic electronic phases in ultra-thin films.

The quantum tunneling effect leads electron transport in porphyrins

A research center of the CSIC participates in a study that refutes the hypothesis that their movement is based on jumps from one region to another. The porphyrins may be used in quantum computing since they keep the wave nature of electrons.

Physicists develop new insight into how disordered solids deform

In solid materials with regular atomic structures, figuring out weak points where the material will break under stress is relatively easy. But for disordered solids, like glass or sand, their disordered nature makes such predictions much more daunting tasks. Now, a collaboration combining a theoretical model with a first-of-its kind experiment has demonstrated a novel method for identifying "soft spots" in such materials.
