Does quantum theory imply the entire Universe is preordained? – Nature.com
Is cosmic evolution a single track with no choice about the destination?Credit: Getty Was there ever any choice in the Universe being as it is? Albert Einstein could have been wondering about this when he remarked to mathematician Ernst Strauss: What Im really interested in is whether God could have made the world in a different way; that is, whether the necessity of logical simplicity leaves any freedom at all. US physicist James Hartle, who died earlier this year aged 83, made seminal contributions to this continuing debate.
Scientists measure entanglement at the LHC | symmetry magazine – Symmetry magazine
On the smallest level, the universe operates in such a bizarre way that even Albert Einstein had a difficult time making sense of it. An example of the strangeness in the quantum realmone that has no equivalent in the world as we experience itis the phenomenon of quantum entanglement. In our classical world, if Iman flips a coin in Indonesia and Olaf flips a coin in Norway, both Iman and Olaf have a 50% chance of landing on heads and a 50% chance of landing on tails.
Quantum batteries could charge faster by scrambling the rules of cause and effect – Livescience.com
Quantum batteries of the future could gain charge by breaking the conventional laws of causality, research has shown.
The Holy Grail of Quantum Computing Is Finally Here. Or Is It? – WIRED
Andersen and Lensky of Google disagree. They do not think the experiment demonstrates a topological qubit, because the object cannot reliably manipulate information to achieve practical quantum computing. It is repeatedly stated explicitly in the manuscript that error correction must be included to achieve topological protection and that this would need to be done in future work, they write to WIRED.
Physicist Bob Coecke: Its easier to convince kids than adults about quantum mechanics – The Guardian
Physics The Belgian physicist and industrial musician on replacing maths with pictures, why hes now working in industry and why we all need to understand subatomic physics Zeeya Merali Sat 16 Dec 2023 09.00 EST Belgian physicist and musician Prof Bob Coecke, 55, wants to teach quantum physics to a mass audience.
Breaking Causality: The Revolutionary Power of Quantum Batteries – SciTechDaily
Quantum batteries, with their innovative charging methods, represent a leap in battery technology, promising higher efficiency and wider applications in sustainable energy solutions. Credit: SciTechDaily.com A new way to charge batteries harnesses the power of indefinite causal order. Batteries that exploit quantum phenomena to gain, distribute, and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power applications
Science of Visibility and Invisibility | by Alexandre Kassiantchouk | Time Matters | Dec, 2023 – Medium
Lets explore an object or a particle that was at point A and had velocity v at point A (we dont care about its velocity before or after that). Lets say, we have two observers: a stationary observer at point B, and another observer moving at constant velocity v: the second observer was at point A when the observed object/particle was there, and later he was at some point E at the moment, when the first observer, stationed in B, noticed/saw the object at the point A (after some time delay t for light to travel from A to B). For the moving observer (between A and E), according to Einstein, time slows down by a factor sqrt(1-v/c), where sqrt is square root, and in his frame of reference (where he thinks of himself as not moving) light has travelled not from A to B, but from E to B, and that took tsqrt(1-v/c) time, which is less than t
If Quantum Physics is Queer, What Does it Mean for Quantum Technologies? – Medium
Photo by Jordan McDonald on Unsplash All that we think is obvious in the physical world is, in reality, merely the physical traits that we can see, and which we then measure against the standards we are familiar with. For instance, our common sense would appear to tell us that a big system (such as a forest ecosystem) could only be made up of subsystems (the trees, herbage, animals, water etc) that create a set of rules that linearly correlate with the overall workings of the big system (the forest)
Beyond the Void: New Experiment Challenges Quantum Electrodynamics – SciTechDaily
The X-ray beam from the worlds largest X-ray laser, the European XFEL, only becomes as clearly visible as in the photo in complete darkness and with an exposure time of 90 seconds. In 2024, the first experiments to detect quantum fluctuations in vacuum will take place here
