1 ene 2017 año - IBM Quantum Experience - A 16-qubit quantum computer available for free use on the Internet.

Descripción:

IBM first put a five-qubit (quantum bit) quantum computer on the Internet in 2016 (see Quantum Computing - IBM Q - US), but the following year they added a much more powerful 16-qubit computer. (The qubit is the equivalent for quantum computers of a bit in ordinary computers.) Anyone can use it, free of charge, although there is always a waiting list for appointments.

The usual oversimplified description of quantum computing is that a qubit (pronounced "Q bit") is "both zero and one at the same time." It's closer to say that a qubit is either zero or one, but we don't know which until it is examined at the end of a computation, at which point it becomes an ordinary bit with a fixed value. This means that a quantum computer with 16 qubits isn't quite as powerful as 216 separate computers trying every possible combination of bit values in parallel. We know that certain exponential-time algorithms can be solved in polynomial time by quantum computers, and we know that certain others can't, but there is still a big middle ground of exponential-time algorithms for which we don't know how fast quantum computers can be.

The IBM QX has been used for a wide variety of quantum computations, ranging from academic research to a multiplayer Quantum Battleship game.
