Quantum computers are supposed to transform medicine, AI, and finance. But what would a useful one actually look like, and what would we use it for? A new calculation and a $5 million prize give some surprising answers.

A US court has defended academic freedom:

A US judge has dismissed a defamation lawsuit against scientific publisher Elsevier. The allegations were raised by the company Global Plasma Solutions which produces an air purifier. They were annoyed that Elsevier published a paper by researchers at the Illinois Institute of Technology who questioned whether the technology does what the company promises. They had tested one of the company’s devices and reported in 2021 that it did little to remove airborne particles. The company alleged that the researchers concealed contradictory data and that Elsevier published the paper despite a failed peer review.

On 22 October, a judge in North Carolina rejected the lawsuit. He judged there was insufficient evidence that Elsevier knowingly published false information or recklessly disregarded whether it was true, as would have been required for the defamation claim.

This lawsuit is not an isolated case. I have personally known scientists who were sued by companies for inconvenient findings. Most of the lawsuits were unsuccessful. However, I am afraid that the threat of being sued alone deters some scientists from investigating the claims of companies. I previously talked about this here:
