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 […]
A team of researchers and engineers at Canadian company Xanadu Quantum Technologies Inc., working with the National Institute of Standards and Technology in the U.S., has developed a programmable, scalable photonic quantum chip that can […]
Anyone who has drained a bathtub or stirred cream into coffee has seen a vortex, a ubiquitous formation that appears when fluid circulates. But unlike water, fluids governed by the strange rules of quantum mechanics […]
Protons are one of the main building blocks of the visible universe. Together with neutrons, they make up the nuclei of every atom. Yet, several questions loom about some of the proton’s most fundamental properties, […]
Maryland-based IonQ has entered into a definitive merger agreement with dMY Technology Group III (NYSE: DMYI.U), according to a company statement. The Transaction will result in $650 million in gross proceeds, including a $350 million […]
So there’s an interesting new paper on the arXiv by Feng Pan and Pan Zhang, entitled “Simulating the Sycamore supremacy circuits.” It’s about a new tensor contraction strategy for classically simulating Google’s 53-qubit quantum supremacy […]
The quantum space is barely a space, compared to other more mature deeptech areas, it’s more of a niche. But several quantum technology companies are already proving that they have the potential for commercialization necessary […]
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 […]
