Quantum Noise

Full Title or Meme

Noise arising from the indeterminate state of matter in accordance with fundamental principles of quantum mechanics, specifically the uncertainty principle. Quantum noise is due to the apparently discrete nature of the small quantum constituents such as electrons, as well as the discrete nature of quantum effects, such as photocurrents.

Context

• All observations (measurements) can be reduced to just "clicks".
• The only part of a quantum existence that can be observed is not the wave function, but just the event that occurs when the wave function collapses.

Solutions

1. Create a experimental set-up that can detect the event of interest.

   What most experimenters take for granted before they begin their experiments is infinitely more interesting than any results to which their experiments lead. -- Norbert Wiener

2. Add error correction to quantum computing. Microsoft and Quantinuum say they’ve demonstrated a quantum computing system that can reduce the error rate for data processing by a factor of 800.
