Quantum 7, 1081 (2023). https://doi.org/10.22331/q-2023-08-10-1081 We consider the problem of approximating the ground state energy of a fermionic Hamiltonian using a Gaussian state. In sharp contrast to the dense case [1, 2], we prove that […]
Quantum 7, 1080 (2023). https://doi.org/10.22331/q-2023-08-10-1080 How to understand the set of correlations admissible in nature is one outstanding open problem in the core of the foundations of quantum theory. Here we take a complementary viewpoint […]
Through a new survey, researchers show how mathematical representations named ‘tensor trains’ can help to capture and simulate the dynamics of evolving quantum systems across a range of different scenarios. Click to rate this post! […]
Insider Brief The China Power Podcast interviews a leading scientist about China’s quantum advances. Dr. Edward Parker, a physical scientist at the RAND Corporation, provided insights into China’s ambitions and progress in quantum tech fields, […]
A team led by researchers at Osaka University and University of California, San Diego has conducted simulations of creating matter solely from collisions of light particles. Their method circumvents what would otherwise be the intensity […]
The Executive Order directs the Department of Treasury to establish and implement a program to regulate U.S. investment in quantum computing, artificial intelligence related to military uses, and advanced semiconductors. These technologies are deemed critical […]
The Center for Quantum Information and Control (CQuIC, https://cquic.unm.edu/) at the University of New Mexico invites applications for Postdoctoral Fellowships in theoretical quantum information science (QIS) as part of the National Science Foundation’s Focused Research […]
Quantum 7, 1079 (2023). https://doi.org/10.22331/q-2023-08-09-1079 The cryptographic task of position verification attempts to verify one party’s location in spacetime by exploiting constraints on quantum information and relativistic causality. A popular verification scheme known as $f$-routing […]
Quantum 7, 1078 (2023). https://doi.org/10.22331/q-2023-08-09-1078 Quantum computers hold great promise to enhance machine learning, but their current qubit counts restrict the realisation of this promise. To deal with this limitation the community has produced a […]
Seven years ago, researchers showed that they could strip cells down to their barest fundamentals, creating a life form with the smallest genome that still allowed it to grow and divide in the lab. But […]
