Google has officially announced that it’s achieved quantum supremacy in a new article published in the scientific journal Nature. The announcement comes exactly one month after it initially leaked, when Google’s paper was accidentally published early. Now, however, it’s official, meaning the full details of the research are public, and the broader scientific community can fully scrutinize what Google says it’s achieved.
A new concept for in-space propulsion is proposed in which propellant is not ejected from the engine, but instead is captured to create a nearly infinite specific impulse.
The engine accelerates ions confined in a loop to moderate relativistic speeds, and then varies their velocity to make slight changes to their mass.
