Apr 15, 2022 · You do too, and your knowledge dwarfs mine exponentially because of quantum physics. But then yours — your frame rate, intuition, your knowledge — is dwarfed by the infinite magnitude of the ...

- The quantum world is lumpy. The quantum world has a lot in common with shoes. You can’t just go to a shop and pick out sneakers that are an exact match for your feet.
- Something can be both wave and particle. J. J. Thomson won the Nobel Prize in 1906 for his discovery that electrons are particles. Yet his son George won the Nobel Prize in 1937 for showing that electrons are waves.
- Objects can be in two places at once. Wave-particle duality is an example of superposition. That is, a quantum object existing in multiple states at once.
- It may lead us towards a multiverse. The idea that observation collapses the wave function and forces a quantum ‘choice’ is known as the Copenhagen interpretation of quantum physics.
- Google claims "quantum supremacy" If one quantum news item from 2019 makes the history books, it will probably be a big announcement that came from Google: The tech company announced that it had achieved "quantum supremacy."
- The kilogram goes quantum. Another 2019 quantum inflection point came from the world of weights and measures. The standard kilogram, the physical object that defined the unit of mass for all measurements, had long been a 130-year-old, platinum-iridium cylinder weighing 2.2 lbs.
- Reality broke a little. A team of physicists designed a quantum experiment that showed that facts actually change depending on your perspective on the situation.
- Entanglement got its glamour shot. For the first time, physicists made a photograph of the phenomenon Albert Einstein described as "spooky action at a distance," in which two particles remain physically linked despite being separated across distances.

May 21, 2018 · Philip Ball is a science writer based in London. His next book, How Life Works (University of Chicago Press), will be published in the fall of 2023. This article was originally published with the ...
This article was reviewed by a member of Caltech's Faculty. To conduct quantum science experiments, researchers often work with the smallest objects—and some of the most fragile and sensitive phenomena—in nature. This requires specialized tools and techniques that have advanced in sophistication since the field of quantum mechanics emerged ...
Feb 18, 2020 · One particularly pervasive notion is the idea that consciousness can directly influence quantum systems - and so influence reality. Today we’re going to see where this idea comes from, and ...
