Aleksander Kubica is a postdoctoral fellow at Canada’s Perimeter Institute for Theoretical Physics and Institute for Quantum Computing. And he’s also the winner of the world’s first quantum chess tournament. (It’s now available for streaming on Twitch, and begins with a clip of the late Stephen Hawking playing a 2016 game against Ant-Man star Paul Rudd.) “It’s a complicated version of…

New Blender Add-On Accurately Models Subatomic Particles, Involves Community with Contest
BlenderArtists.org writes:
To build and model the universe from the Planck scale to galactic scales requires an incredible number of mathematical computations to simulate particles and their interactions, yet the framework of nature and the physics of these interactions should be simple. Blender’s physics engine provides a good base to begin this project, but it will take work from the community to…
Simulating quantum ‘time travel’ disproves butterfly effect in quantum realm
Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no “butterfly effect.” In the research, information—qubits, or quantum bits—’time travel’ into the simulated past. One of them is then strongly damaged, like stepping on a butterfly, metaphorically speaking. Surprisingly, when all qubits return to the ‘present,’ they appear largely unaltered, as if…
Streamlining quantum information transmission
The quantum realm holds the key to the next revolution in communication technology as we know it. With the promise of unprecedented performance and impenetrable security, quantum technology is taking its first steps towards the ultimate goal of applications such as highly encrypted yet nearly fast-as-light financial transactions. However, the ability for quantum computers to communicate with one another has been…
The smallest motor in the world
A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling – and has revealed puzzling phenomena to researchers…
In the quantum realm, cause doesn’t necessarily come before effect
In everyday life, causes always precede effects. But new experiments suggests that no such restriction applies in the quantum world Source: https://www.newscientist.com/article/mg24532650-700-in-the-quantum-realm-cause-doesnt-necessarily-come-before-effect/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Tuning optical resonators gives researchers control over transparency
In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media. …
The Quantum World May Have a Favorite Flavor, Tantalizing Results Suggest
The world of the teensy-tiny, the quantum realm, could have a favorite flavor. Here’s why that’s a big deal. Source: https://www.livescience.com/quantum-world-flavor-anomalies.html
Quantum physics: Our study suggests objective reality doesn’t exist
Alternative facts are spreading like a virus across society. Now it seems they have even infected science—at least the quantum realm. This may seem counter intuitive. The scientific method is after all founded on the reliable notions of observation, measurement and repeatability. A fact, as established by a measurement, should be objective, such that all observers can agree with it. …
Turning water into ice in the quantum realm
When you pop a tray of water into the freezer, you get ice cubes. Now, researchers from the University of Colorado Boulder and the University of Toronto have achieved a similar transition using clouds of ultracold atoms. …
