The moment I meet Horst Schmidt-Böcking outside the Bockenheimer Warte subway stop just north of the downtown area of Frankfurt, Germany, I know I have come to the right place. After my “Hi, thank you for meeting me,” his very first words are “I love Otto Stern.” My trip on this prepandemic morning in November … Read more

Water flows mysteriously well through narrow carbon nanotubes, but now there is an explanation: it may all be due to quantum friction Physics 2 February 2022 By Chen Ly Narrow carbon nanotubes behave in an unusual way Shutterstock / ustas7777777 Water flows more easily through narrower carbon nanotubes than larger ones and we have struggled … Read more
My girlfriend, “Emily,” often tells me her dreams, and I, less often, tell her mine, which are usually too murky and disjointed to share. We try to make sense of our dreams, to find meaning in them. What do they reveal about our fears and desires? Interpreting dreams is an imperfect, highly subjective art, as … Read more
Bitcoin is theoretically vulnerable to being cracked by quantum computers, but calculations show they would need to be a million times larger than those that exist today Technology 25 January 2022 By Matthew Sparkes Bitcoin could one day be threatened by quantum computers – but not yet blackdovfx/Getty Images Quantum computers would need to become … Read more
Scientific American January 2022 Measuring the time it takes particles to travel between two points may be the best test yet for Bohmian mechanics A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum … Read more
A major milestone has just been reached in quantum computing. Three separate teams around the world have passed the 99 percent accuracy threshold for silicon-based quantum computing, placing error-free quantum operations within tantalizing grasp. In Australia, a team led by physicist Andrea Morello of the University of New South Wales achieved 99.95 percent accuracy … Read more
Most quantum computers are based on superconductors or trapped ions, but an alternative approach using ordinary atoms may have advantages Technology 18 January 2022 By Alex Wilkins Quantum computers use the properties of quantum physics to perform calculations ArtemisDiana/Shutterstock A quantum computer that uses ordinary atoms to perform calculations could be a rival to more … Read more
Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers. Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a … Read more
