The Download: IBM’s quantum ambitions, and tasting lab-grown burgers

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

IBM wants to build a 100,000-qubit quantum computer

What's happening: Last year, IBM took the record for the largest quantum computing system with a processor containing 433 quantum bits, or qubits, the fundamental building blocks of quantum information processing. Now, the company has set its sights on a much bigger target: a 100,000-qubit machine that it aims to build within 10 years.

Why it matters: The project is part of IBM's plans to push quantum computing into the realm of full-scale operation, where the technology could potentially tackle pressing problems that no standard supercomputer can solve.

The potential: The idea is that the 100,000 qubits will work alongside the best classical" supercomputers to achieve new breakthroughs in drug discovery, fertilizer production, battery performance, to name just a few fields. Read the full story.

Here's what a lab-grown burger tastes like

Eating meat has an undeniable impact on the planet. Animal agriculture makes up nearly 15% of global greenhouse-gas emissions, and beef is a particular offender, with more emissions per gram than basically any other meat.

Intrigued by the promise of lab-grown meat, our climate reporter Casey Crownhart decided to see whether a cultivated Wagyu burger could ever live up to the lofty promises made by alternative meat companies. Find out how she got on.

The big story

How technology helped archaeologists dig deeper

April 2021

Construction workers in New York's Lower Manhattan neighborhood were breaking ground for a new federal building back in 1991 when they unearthed hundreds of coffins. The site, known as the African Burial Ground, became one of the best-known archaeological discoveries in the country and is now a national monument.

The African Burial Ground project was among the first to use a new constellation of bioarchaeology" tools that went way beyond the traditional pickaxes and brushes. But this was simply the first stage of a much broader archaeological revolution that brought scientists and humanities scholars together to generate data about our ancestors. Read the full story.
