In modern computing the smallest piece of information is the bit. A bit can have two values: 0 or 1. In quantum computing the smallest piece of information is the quantum bit. Similar to the traditional bit it can have the value of 0 or 1, but additionally to the traditional 0 and 1 values a qubit can be in a superposition of both 0 and 1 states. The power of the superpositions in qubits becomes clear when large arrays of high fidelity entangled qubits can be set to specific values with one operation. The power of supercomputing is expected to be orders of magnitude stronger than the current traditional computers. Encryption by quantum computers is likely to be impossible to decrypt by traditional computers and vice versa. Encrypted bitcoins and other current encryptions are decrypted with ease by quantum computers.
