Here are the facts about Quantum Computing

Google said its researchers have solved the calculation in 3 minutes and 20 seconds and the largest computers cannot complete in under 10,000 years. With that calculation, the company has achieved a milestone that scientists have been working since the 1980s and the breakthrough is called, “Quantum Computing.” 




What is quantum computing and how does it work?
Quantum computers encode information as quantum bits, or qubits, which can exist in superposition. Qubits represent atoms, ions, photons or electrons, and their respective control devices that are working together to act as computer memory and a processor.

What is the use of quantum computing?
Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation. A quantum computer is used to perform such computation, which can be implemented theoretically or physically.

What is the difference between quantum computing and conventional computing?
Conventional computing uses binary codes i.e. bits 0 or 1 to represent information. Quantum computing use Qubits i.e. 0, 1 and superposition state of both 0 and 1 to represent information.

Will quantum computers replace classical computers?
Classical computers are better at some tasks than quantum computers (email, spreadsheets, and desktop publishing to name a few). The intent of quantum computers is to be a different tool to solve different problems, not to replace classical computers.
