Light controls two-atom quantum computation

Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes. Someday, new quantum technologies could allow for making these wishes ...

New input for quantum simulations

An international group of researchers, including UvA physicist Michael Walter, have devised new methods to create interesting input states for quantum computations and simulations. The new methods can be used to simulate ...

Accelerating light beams in curved space

By shining a laser along the inside shell of an incandescent light bulb, physicists have performed the first experimental demonstration of an accelerating light beam in curved space. Rather than moving along a geodesic trajectory ...

General approach for the solution of lattice gauge theories

It is not the daily occurrence that physicists from entirely different fields closely work together. However, in theoretical physics a general ansatz can offer solutions for a large variety of problems. A team of scientists ...

Scientists lay out why some origami won't fold under pressure

Scientists and engineers are fascinated by self-folding structures. Imagine the possibilities: heart stents that unfold in the right location or pop-up tents that assemble at the press of a button, as well as nanoscale versions ...

Error-free into the quantum computer age

A study led by physicists at Swansea University in Wales, carried out by an international team of researchers and published in the journal Physical Review X shows that ion-trap technologies available today are suitable for ...

Two holograms in one surface

A team at Caltech has figured out a way to encode more than one holographic image in a single surface without any loss of resolution. The engineering feat overturns a long-held assumption that a single surface could only ...

How suspended particles influence liquid flow dynamics

One of the most prominent publications in physics, Physical Review X, accepted an article by Sangwoo Shin, a University of Hawaiʻi at Mānoa assistant professor in mechanical engineering. The article is titled Accumulation ...

Controlling a vortex using polymers

A vortex in the atmosphere can churn with enough power to create a typhoon. But more subtle vortices form constantly in nature. Many of them are too small to be seen with the naked eye.
