Google Wants to Build a Useful, Commercial-Grade Quantum Computer Before 2030

Google wants to build a useful quantum computer by 2029
Google is aiming to build a "useful, error-corrected quantum computer" by the end of the decade, the company explained in a blog post. The search giant hopes the technology will help solve a range of big problems like feeding the world and climate change to developing better medicines. To develop the technology, Google has unveiled a new Quantum AI campus in Santa Barbara containing a quantum data center, hardware research labs, and quantum processor chip fabrication facilities. It will spend billions developing the technology over the next decade, The Wall Street Journal reports.
The target announced at Google I/O on Tuesday comes a year and a half after Google said it had achieved quantum supremacy, a milestone where a quantum computer has performed a calculation that would be impossible on a traditional classical computer. Google says its quantum computer was able to perform a calculation in 200 seconds that would have taken 10,000 years or more on a traditional supercomputer. But competitors racing to build quantum computers of their own cast doubt on Google's claimed progress. Rather than taking 10,000 years, IBM argued at the time that a traditional supercomputer could actually perform the task in 2.5 days or less.
This extra processing power could be useful to simulate molecules, and hence nature, accurately, Google says. This might help us design better batteries, creating more carbon-efficient fertilizer, or develop more targeted medicines, because a quantum computer could run simulations before a company invests in building real-world prototypes. Google also expects quantum computing to have big benefits for AI development.
If it's useful for simulations and AI, then video games and smartphones could use it by 2045.
