Quantum 5, 404 (2021). https://doi.org/10.22331/q-2021-03-08-404 The double slit experiment provides a clear demarcation between classical and quantum theory, while multi-slit experiments demarcate quantum and higher-order interference theories. In this work we show that these experiments […]
For decades, the computer chips that run everything from PCs to spaceships have looked remarkably similar. But as Moore’s Law slows, industry leaders are moving towards specialized chips, which experts say threatens to undermine the […]
Quantum 5, 403 (2021). https://doi.org/10.22331/q-2021-03-07-403 We study the query complexity of quantum learning problems in which the oracles form a group $G$ of unitary matrices. In the simplest case, one wishes to identify the oracle, […]
Quantum 5, 402 (2021). https://doi.org/10.22331/q-2021-03-07-402 An $noverset{p}{mapsto}m$ random access code (RAC) is an encoding of $n$ bits into $m$ bits such that any initial bit can be recovered with probability at least $p$, while in […]
Quantum 5, 401 (2021). https://doi.org/10.22331/q-2021-03-02-401 Self-testing is a method to certify devices from the result of a Bell test. Although examples of noise tolerant self-testing are known, it is not clear how to deal efficiently […]
Wonder material graphene is often touted as a potential way around the death of Moore’s Law, but harnessing its promising properties has proven tricky. Now, researchers have shown they can build graphene chips 100 times […]
Air taxis still seem like a far-off concept, especially in a time when a lot of people have stopped flying or using shared transportation altogether. But the technology has continued to advance nonetheless, as has […]
Facial recognition technology has been banned by multiple US cities, including Portland, Boston, and San Francisco. Besides the very real risk of the tech being biased against minorities, the technology also carries with it an […]
We’ve probed the depths of Earth’s deepest trench, sent rovers to Mars, and observed other worlds billions of light years away. Yet we’ve never been able to decipher the mysterious, bizarre, and disjointed world of […]
ARTIFICIAL INTELLIGENCE A New Artificial Intelligence Makes Mistakes—on PurposeWill Knight | Wired “It took about 50 years for computers to eviscerate humans in the venerable game of chess. A standard smartphone can now play the kind of […]
