Quantum Computer Start-UP Quantinuum control room
Quantinuum
The US military launched an attempt to determine who might be able to build a really useful quantitative computer within a decade, and what might be good for it.
There are more than six companies that currently build quantum computers, but it is not clear that any of them will eventually lead to the production of devices that have a tangible impact on American industries and the economy. The American Defense Research Projects Agency (DARPA) has started a program to find out.
