Google recently came with a ground-breaking announcement in their article that revealed it has achieved quantum supremacy. To elaborate, the U.S. tech giant claimed that their quantum computer, named Sycamore, became successful in solving a complex mathematical problem in 200 seconds beating the current IBM-made fastest supercomputer in the world (named Summit) that would take 10,000 years to solve the same problem.
Those who do not know what a quantum computer is, let us explain that it is something that functions beyond the classical supercomputing system with the potential to solve complex problems more rapidly. A classical computer works on the binary rules that follow the classical physics using bits which can be either 1 or 0. For example, phone, tablet, or laptop are nothing but classical computers.
However, a quantum computer follows the laws of quantum physics and uses quantum bits or qubits instead of bits. Qubits in a quantum computer could either take the position of 1 or 0 or different combinations of it (or different states) with a probability assigned to each of the states.
When Google’s article was published in Nature it created a lot of chaos. There were a lot of experts talking about its unprecedented implications that a supreme quantum computer holds in the distant future such as understanding nature in the best possible way or creating the most advanced medicines that can cure terminal diseases. The revelation also resulted in a tall claim with respect to the crypto coin network, particularly Bitcoin.
One author in a Medium Post (deleted afterwards) used Google’s benchmark performance tests and estimated that gaining quantum supremacy also means that the 54-qubit Sycamore could mine the remaining 3 million bitcoins in less than 2 seconds, which would normally take 121 years. Bitcoin mining mainly refers to solving complex mathematical problems thereby producing new bitcoin and securing the Bitcoin payment network by verifying transaction information.
We do not yet know for sure whether Sycamore could really do such things with Bitcoin mining as some computational errors were noticed in the author’s estimation such as considering the production of 1 Bitcoin every 10 minutes instead of actual generation of roughly 12.5 bitcoins in each transaction block of 10 minutes. Lastly, IBM has also squashed Google’s claim of achieving quantum supremacy stating that their Summit could actually solve the Sycamore’s task in two and a half days, not 10,000 years!
