IBM has unveiled an advanced quantum processor that is part of an effort to build super-fast computers.

The new chip has 127 qubits, twice as many as the previous IBM processor. Qubits (quantum bits) are the most basic units of information in quantum computer.

On recent years, there are a lot of interest in the machine because of the potential to vastly improve computing power that could help on developing new materials or improving aspects of artificial intelligence.

In classical computers, the unit of information is called a ‘bit’ that will have value of zero or one. For quantum system, it is equivalent as the qubit can be both zero and one at the same time.

This is the concept of superposition where something exist in multiple states at once.
