The discovery of new quantum materials with magnetic properties could pave the way for ultra-fast and considerably more energy-efficient computers and mobile devices. So far, these types of materials have been shown to work only […]
The ATLAS collaboration, the large research consortium involved in analyzing data collected by the ATLAS particle collider at CERN, recently observed the electroweak production of two Z bosons and two jets. This crucial observation, presented […]
Developing new quantum devices relies on controlling how electrons behave. A material called graphene, a single layer of carbon atoms, has fascinated researchers in recent years because its electrons behave as if they have no […]
Despite the wild success of ChatGPT and other large language models, the artificial neural networks (ANNs) that underpin these systems might be on the wrong track. For one, ANNs are “super power-hungry,” said Cornelia Fermüller, […]
Quantum 7, 980 (2023). https://doi.org/10.22331/q-2023-04-13-980 Device-independent (DI) protocols, such as DI conference key agreement (DICKA) and DI randomness expansion (DIRE), certify private randomness by observing nonlocal correlations when two or more parties test a Bell […]
Quantum 7, 979 (2023). https://doi.org/10.22331/q-2023-04-13-979 A web of cohomological facts relates quantum error correction, measurement-based quantum computation, symmetry protected topological order and contextuality. Here we extend this web to quantum computation with magic states. In […]
Introduction Overall, the US is one of the leading players in the research, investment and private sector in quantum tech globally. Going back a few decades, the US was the dominant player until China made […]
Quantum 7, 978 (2023). https://doi.org/10.22331/q-2023-04-13-978 Extracting classical information from quantum systems is an essential step of many quantum algorithms. However, this information could be corrupted as the systems are prone to quantum noises, and its […]
Quantum 7, 977 (2023). https://doi.org/10.22331/q-2023-04-13-977 Simulating many-body quantum systems is a promising task for quantum computers. However, the depth of most algorithms, such as product formulas, scales with the number of terms in the Hamiltonian, […]
This article on Chinese Quantum Companies and National Strategy was written from information and data on The Quantum Insider’s proprietary market intelligence platform and premium report: Quantum Technology in China. Introduction A Brief Overview of […]
