Describe a brief understanding of quantum computers
Answers
Answer:
Quantum computation is the field that investigates the computational power and other properties of computers based on quantum-mechanical principles. An important objective is to find quantum algorithms that are significantly faster than any classical algorithm solving the same problem.
Explanation:
1. The process of miniaturization that has made current classical computers so powerful and cheap, has already reached micro-levels where quantum effects occur. Chip-makers tend to go to great lengths to suppress those quantum effects, but instead one might also try to work with them, enabling further miniaturization.
2. Making use of quantum effects allows one to speed- p certain computations enormously (some1 times exponentially), and even enables some things that are impossible for classical computers.
3. Finally, one might state the main goal of theoretical computer science as “study the power and limitations of the strongest-possible computational devices that Nature allows us.” Since our current understanding of Nature is quantum mechanical, theoretical computer science should arguably be studying the power of quantum computers, not classical ones.
