What is Quantum Processing Unit (QPU) — Difference Between QPU and CPU

Quantum Processing Unit (QPU)

The term ‘Quantum Chip’ or “quantum processing unit’ or simply ‘QPU’ refers to a physical chip (hard chip) that has many interconnected quantum bits (qubits). Same as CPU, the QPU also serves the basic building block of a quantum computer. The quantum processing unit is built on quantum physics (the physics of sub-atomic particles including quantum entanglement and quantum superposition).

Difference Between QPU and CPU

• A quantum computer (with QPU) works in a fundamentally way that a CPU or classical computer’s basic unit is ‘bit’ while the basic unit of a QPU is ‘qubit’. A bit is a binary data which consist of 0 or 1. If you are a science student, you must knew about ‘binary system’ and ‘decimal system’.
• A processed ‘bit’ is implemented by one of two levels of low DC voltage in traditional computer systems. The most recent variation of this concept is ‘qubit’. The word ‘qubit’ was first used by Benjamin Schumacher.
• ‘Qubits’ use the phenomenon of superposition, which enables them to be in numerous states at the same time, in contrast to bits, which can only be in 0 or 1.
