Dissecting the Quantum Illusion: Debunking the Cheshire Cat Effect
What actually happens is much weirder, and may help us understand more about quantum mechanics.
The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind. Similarly, in a 2013 paper, researchers claimed quantum particles are able to separate from their properties, with the properties traveling along paths the particle cannot. They named this the quantum Cheshire cat effect. Researchers since have claimed to extend this further, swapping disembodied properties between particles, disembodying multiple properties simultaneously, and even “separating the wave-particle duality” of a particle.
Contextuality in Quantum Mechanics.
Making More Magnetism Possible with Topology
Researchers who have been working for years to understand electron arrangement, or topology, and magnetism in certain semimetals have been frustrated by the fact that the materials only display magnetic properties if they are cooled to just a few degrees above absolute zero.
A new MIT study led by Mingda Li, associate professor of nuclear science and engineering, and co-authored by Nathan Drucker, a graduate research assistant in MIT’s Quantum Measurement Group and PhD student in applied physics at Harvard University, along with Thanh Nguyen and Phum Siriviboon, MIT graduate students working in the Quantum Measurement Group, is challenging that conventional wisdom.
The open-access research, published in Nature Communications, for the first time shows evidence that topology can stabilize magnetic ordering, even well above the magnetic transition temperature — the point at which magnetism normally breaks down.

‘Sudden death’ of quantum fluctuations defies current theories of superconductivity
Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor.
The research promises to enhance our understanding of quantum physics in solids in general and also propel the study of quantum condensed matter physics and superconductivity in potentially new directions. The results were published in the journal Nature Physics in a paper titled “Unconventional Superconducting Quantum Criticality in Monolayer WTe2.”
The researchers, led by Sanfeng Wu, assistant professor of physics at Princeton University, found that the sudden cessation (or “death”) of quantum mechanical fluctuations exhibits a series of unique quantum behaviors and properties that appear to lie outside the purview of established theories.
From i to u: Searching for the quantum master bit
Year 2014 Basically once the master qubit is found it could even lead to a sorta master algorithm. Also it could show who actually pulls the strings of reality.
Whatever the u-bit is, it rotates quickly (Image: Natalie Nicklin)
Our best theory of nature has imaginary numbers at its heart. Making quantum physics more real conjures up a monstrous entity pulling the universe’s strings
Leader: “The u-bit may be omniscient, but it’s no God particle”
A Black Hole Breakthrough Might Actually Solve the Information Paradox
The key to understanding our universe lies in two theories—one of the generally-very-big and one of the generally-very-small. Albert Einstein’s Theory of General Relativity explains things like gravity and time, while Quantum Field Theory explores the subatomic world. However, one celestial object frustrates astrophysicists and quantum theorists in equal measure: black holes.
Because black holes release Hawking radiation (named for famous physicist Stephen Hawking), they eventually evaporate, which seemingly destroys the information that fell into the black hole. However, quantum field theory states that information cannot be destroyed. Result? Paradox.
Scientists Have Eye on Quantum Technology For Age-related Macular Degeneration Detection
PRESS RELEASE — Scientists are working on a new device that could lead to a reduction in the number of people who go blind from age-related macular degeneration (AMD). Researchers at Centre for Eye and Vision Research (CEVR) are using quantum technology to detect the disease in its early stages where treatment may help preserve vision.
As part of a visit during the recent Hong Kong Laureate Forum, young scientists from across the world learned how the new low-cost ophthalmic diagnostic device could be part of routine GP and outpatient check-ups.
AMD which affects more than 200 million people worldwide, causes changes to the macula, which can lead to problems with central, detailed vision.
Avshalom Elitzur on Biology, Thermodynamics, and Information: A Tutorial
Dr. Avshalom Cyrus Elitzur (Hebrew: אבשלום כורש אליצור; born 30 May 1957) is an Israeli physicist, philosopher and professor at Chapman University. He is also the founder of the Israeli Institute for Advanced Physics. He obtained his PhD under Yakir Aharanov. Elitzur became a household name among physicists for his collaboration with Lev Vaidman in formulating the “bomb-testing problem” in quantum mechanics, which has been validaded by two Nobel-prize-winning physicists. Elitzur’s work has sparked extensive discussions about the foundations of quantum mechanics and its interpretations, including the Copenhagen interpretation, many-worlds interpretation, and objective collapse models. His contributions have had a profound impact on both physics and philosophy, influencing debates about measurement, the role of observers, and the ontology of quantum states. Elitzur has also engaged in discussions about consciousness, the arrow of time, and other foundational topics, including a recent breakthrough in bio-thermodynamics and the “ski-lift” pathway.
