  摘要：Quantum systems have entered a competitive regime in which classical computers must make approximations to represent highly entangled quantum states(1,2). However, in this beyond-classically-exact regime, fidelity comparisons between quantum and classical systems have so far been limited to digital quantum devices(2-5), and it remains unsolved how to estimate the actual entanglement content of experiments(6). Here, we perform fidelity benchmarking and mixed-state entanglement estimation with a...

  摘要：Gravity simulators(1) are laboratory systems in which small excitations such as sound(2) or surface waves(3,4) behave as fields propagating on a curved spacetime geometry. The analogy between gravity and fluids requires vanishing viscosity(2-4), a feature naturally realized in superfluids such as liquid helium or cold atomic clouds(5-8). Such systems have been successful in verifying key predictions of quantum field theory in curved spacetime(7-11). In particular, quantum simulations of rotati...

  摘要：Words and images experienced by an infant wearing sensors during their daily life have led to efficient machine learning, pointing to the power of multimodal training signals and to the potentially exploitable statistics of real-life experience.
• Research assessments are still not fit for purpose - here's how to change things AI翻译

  摘要：A move away from narrow assessment metrics such as high-impact publications is welcome, but a lack of planning and consultation mean the replacements are often no better.

  摘要：Several genetic risk factors for Alzheimer's disease implicate genes involved in lipid metabolism and many of these lipid genes are highly expressed in glial cells1. However, the relationship between lipid metabolism in glia and Alzheimer's disease pathology remains poorly understood. Through single-nucleus RNA sequencing of brain tissue in Alzheimer's disease, we have identified a microglial state defined by the expression of the lipid droplet-associated enzyme ACSL1 with ACSL1-positive micro...
