Nobel Prize in Physics 2025 vs Ukulele Vibrating Strings

The 2025 Nobel Prize in Physics was awarded to John Clarke, Michel H. Devoret, and John M. Martinis 

  • for experiments that revealed quantum physics in action,
  • particularly their pioneering work in demonstrating that quantum mechanical effects can manifest at a macroscopic (larger-than-atomic) scale.
The general idea is that the microscopic world of quantum mechanics contains wonderful subtle small-scale phenomena of superposition and entanglement not present in the macroscopic world where averaging destroys small scales. 

The idea of quantum computing is to use quantum states in superposition to perform computations in parallel and so reach entirely new levels of computational power. 

The idea of the Nobel Prize is to upscale quantum capacities for parallel computing to larger scales allowing more efficient error control and input/output.  

Upscaling of microscopics to macroscopics is opposite to the downscaling of mechanical calculators to microprocessor of computers behind the digital revolution.  

There is a clear connection to recent blog posts asking to what extent the microscopic quantum world is different from the macroscopic world, with the conclusion that the difference is not so big after all. 

If so, it should be possible to find the wonderful quantum effects like superposition directly on familiar macro-scales like a vibrating string. This opens to use e g an ukulele as efficient computing device in room temperature, instead of super-conduction at very low temperatures.
