2011 First commercially available quantum annealer D-Wave Systems announce D-Wave One , described as " the world ' s first commercially available quantum computer ", operating on a 128-qubit chipset using quantum annealing ( a general method for finding the global minimum of a function by a process using quantum fluctuations ) to solve optimisation problems .
2019 Google declares it ’ s attained quantum supremacy Google claims it has achieved quantum supremacy , saying its experimental quantum computer , Sycamore , performed a series of operations in 200 seconds that would take a supercomputer about 10,000 years to complete . IBM responds , suggesting it could take 2.5 days instead of 10,000 years .
2016 Quantum computing made available through the cloud IBM Research announces that it is making quantum computing available to members of the public via the cloud for the first time . In late 2017 and early 2018 , IBM , Intel , and Google each report testing quantum processors containing 50 , 49 , and 72 qubits respectively .

‘ Super fridge ’ to cool tomorrow ’ s quantum data centres IBM reveals the world ’ s largest cryogenic dilution fridge , able to cool to 25 milli-Kelvin ( mK ), just thousandths of a degree above absolute zero . Large-scale cryogenic systems will be required to meet the cooling needs of tomorrow ’ s quantum data centres , as researchers aim for machines with one million qubits .
