KEY POINTS

Quantum computers

·         Quantum computers use quantum mechanical techniques to do their computing.

·         It takes advantage of the strange ability of subatomic particles to exist in more than one state at any time.

·         Instead of bits, which conventional computers use, a quantum computer uses quantum bits—known as qubits.

·         Their fundamental unit, called a qubit (quantum bit), still assumes one of two outcomes when it is measured: 0 and 1, like a bit.

·         But, according to quantum mechanics, the state we find a qubit in can also be a “superposition” of both 0 & 1.

Advantages of Quantum computers

·         Quantum computers will be much faster than regular ones. So, operations can be done much more quickly.

·         It uses lesser energy than classical computers.

·         Easily crack secret codes and its application in cryptography makes the systems much more secure than their conventional analogues.

·         It can store more information than a conventional one.

·         Fast in searching databases.
