When is The Quantum Computer Will Be Available to Public?
 

Quantum computers already exist today, but not in a form the general public can buy or use at home. Companies like IBM, Google, and Amazon offer cloud access to small quantum processors, but these are mainly for research and education.

For everyday public use, we’re still far away. Most experts estimate:
10–20 years before quantum computers become stable enough for broader commercial use
Much longer before they are affordable or practical as personal devices

Right now, they require extreme cooling, complex hardware, and specialized environments. So while the technology is advancing fast, true public availability is still in the future.
