Deconstructing Schrödinger's cat

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that ...

Laser physics: At the pulse of a light wave

Physicists in the Laboratory for Attosecond Physics at Ludwig-Maximilians-Universitaet (LMU) in Munich and at the Max Planck Institute for Quantum Optics (MPQ) have developed a novel type of detector that enables the oscillation ...

Quantum material goes where none have gone before

Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he's finally found a traveler that can traverse the final frontier.

Introducing quantum convolutional neural networks

Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics ...

Complex quantum teleportation achieved for the first time

Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers.

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...

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 ...

Physicists find first possible 3-D quantum spin liquid

There's no known way to prove a three-dimensional "quantum spin liquid" exists, so Rice University physicists and their collaborators did the next best thing: They showed their single crystals of cerium zirconium pyrochlore ...
