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 […]
A German cryptographic researcher, Dr. Claus Peter Schnoor, has published a paper on the website of The International Association for Cryptologic Research that describes a new classical method of factoring large integers based upon a […]
Several software announcements have been made in the past few days. These include Google’s release of version 0.10.0 of Cirq, Cambridge Quantum Computing’s (CQC) release of version 0.8 of their tket software development kit, and […]
