In a quantum computer, the bits that are the cornerstone of a classical computer are replaced with qubits. Unlike the ordinary bits, which can only assume the values 0 and 1, qubits or quantum bits can also be in what is called a superposition of 0 and 1.

By connecting many qubits together in the phenomenon of entanglement, quantum computers could explore calculations that are impossible on the classical computers we know today, and they will be able to do it much, much faster. They can be used for example to develop new medicine and develop new financial models.

Massive investments are being made in the development of quantum computers, and today they have come so far that they are on the threshold of unleashing the enormous potential of quantum technology.
