D-Wave One First Commercial Quantum Computer
D-Wave One is the first commercially available quantum computer, its 128-qubit processor can only handle very specific tasks and is easily outperformed by traditional CPUs, it represents a revolution in the field of supercomputing. D-Wave scale up to thousands or tens-of- thousands of qubits, complex number theory problems, and cryptographic systems can crumble before the mighty power of quantum annealing. The Price seems to be large at $10,000,000. Hit one the source link to know more about D-Wave One
