How is a quantum computer different

from a classical computer?


The Basics:

  • Both classical computers and quantum computers are based on a binary system consisting of 1's and 0's.

  • With a classical computer, this is generally represented with either a high voltage pulse (1) or a low voltage pulse (0).

  • Instead of simply an electric pulse, a quantum computer will use various states of subatomic particles to represent data.

  • Quantum computers use the principles of quantum mechanics to perform operations on data.
