About Quantum computing:
- It is a type of computation that harnesses the collective properties of quantum states, such as superposition, interference, and entanglement, to perform calculations.
- It harnesses the phenomena of quantum mechanics to deliver a huge leap forward in computation to solve certain problems.
- Quantum mechanics is a science that describes the unique behavior of matter and energy at the atomic and subatomic level. These particles don’t obey the laws of classical Newtonian physics.
Need: Until now, we’ve relied on supercomputers to solve most problems. These are very large classical computers, often with thousands of classical CPU and GPU cores. However, supercomputers aren’t very good at solving certain types of problems.
- Supercomputers don’t have the working memory to hold the myriad combinations of real world problems.
- Supercomputers have to analyze each combination one after another, which can take a long time.
How Quantum computer works: It works on:
- “superposition,” meaning they can exist in multiple states(both 0,1 at the same time) at the same time. It is unlike classical computers where information is processed in ‘bits’ or 1s and 0s, following classical physics.
- “entanglement,” where two or more particles are inextricably linked and mirror each other exactly, even when separated by great physical distance.
