SUMMARY

Quantum computers are revolutionizing the size of computing devices, utilizing elementary particles for calculations. The discussion centers on the theoretical limits of miniaturization, with the Planck length identified as a potential boundary for physical size. The concept of "phantom" computers, which may not be constructed from conventional matter, is also explored, drawing inspiration from Isaac Asimov's "The Last Question." The conversation highlights the ongoing evolution of computing technology and its implications for the future.

PREREQUISITES
  • Understanding of quantum computing principles
  • Familiarity with elementary particle physics
  • Knowledge of the Planck length in theoretical physics
  • Awareness of science fiction concepts in technology
NEXT STEPS
  • Research advancements in quantum computing technology
  • Explore the implications of the Planck length in physics
  • Investigate the concept of non-material computing devices
  • Read Isaac Asimov's "The Last Question" for context on phantom computers
USEFUL FOR

Physicists, computer scientists, futurists, and science fiction enthusiasts interested in the limits of computing technology and theoretical physics.

computers today are getting smaller and smaller. Now we have developed quantum computers, using elementary particles perform calculations. When do you suppose we will hit a point where we get computers as small as we can get them? How small will they can possibly be?

Is there a possibility we'll have a "phantom" computer, not made of conventional matter, like in Issac Asimov's "The Last Question"

EDIT: I'm sorry, I did not notice the computer section until after I posted this.

It's hard to put a size to this as I guess what we think are the smallest known particles may not be findamental and so may open up a whole new range of possibilities.
 
Of course, if you need an absolute number for this question, it would be the Planck length.
