Normal computers work with bits, which may consist of ones and zeros. Quantum computers use so-called qubits; special bits that adhere to the rules of quantum mechanics.
Qubits have the special property that they can be both zero and one at a time, a so-called superposition. The quantum computer used by IBM has five of these qubits. Quantum computers have to IBM an estimated 50 to 100 qubits required to match the computing power of a modern computer

interested parties can use the cloud service from IBM to write programs remotely on the quantum computer, which also run on the system. The clodudienst IBM hopes to create a community of researchers who together can gain more knowledge about the functioning of qubits and quantum computers.
Working in addition, through the cloud, the advantage that the system can be protected from overheating and other hazards. The physical system is in a cold store in an IBM lab in New York
