"The power and potential of computation to tackle important problems has never been greater. In the last few years, the cost of computation has continued to plummet. The Pentium IIs we used in the first year of Google performed about 100 million floating point operations per second. The GPUs we use today perform about 20 trillion such operations — a factor of about 200,000 difference — and our very own TPUs are now capable of 180 trillion (180,000,000,000,000) floating point operations per second.

Even these startling gains may look small if the promise of quantum computing comes to fruition. For a specialized class of problems, quantum computers can solve them exponentially faster. For instance, if we are successful with our 72 qubit prototype, it would take millions of conventional computers to be able to emulate it. A 333 qubit error-corrected quantum computer would live up to our name, offering a 10,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000x speedup."
