is likely to maintain a speed advantage over quantum computers over the next 10 years. Hence if quantum computers capable of breaking Bitcoin are indeed developed, they would also be a risk to banks and would have far reaching consequences). Org/abs/1710.10377 : Quantum Attacks On Bitcoin, And How To Protect Against Them. If a group of miners controls more than 50 percent of the computational power on the network, it can always mine blocks faster than whoever has the other 49 percent.
Why Quantum Computing s Threat To Bitcoin And Blockchain Is A Long Way Off.
But Googles quantum computing expert John Martinis wants to put their minds at ease.
At a major crypto event at University of California Santa Barbara this week, Martinis talked about why it could take a decade or more to build a quantum computer.
This is really, really hard, way harder than building a classical computer, he said.
Some computer scientists say quantum computers are moving closer to reality and will cripple bitcoins encryption systems and doom bitcoin.

The real power of quantum computing can be unleashed only when the number of qubits increases. According to, the Economist, a 300-qubit quantum computer can have more possible states than the number of atoms in this universe.
