Two below-threshold surface code memories on Willow, a distance-7 code and a distance-5 code integrated with a real-time decoder, indicate device performance that, if scaled, could realize the operational requirements of large-scale fault-tolerant quantum algorithms.
An AI co-scientist is introduced, a multi-agent system built on Gemini 2.0 intended to help uncover new, original knowledge and to formulate demonstrably novel research hypotheses and proposals, building upon prior evidence and aligned to scientist-provided research objectives and guidance.
It is shown that superconducting quantum annealing processors can rapidly generate samples in close agreement with solutions of the Schrödinger equation, demonstrating area-law scaling of entanglement in the model quench dynamics of two-, three- and infinite-dimensional spin glasses, supporting the observed stretched-exponential scaling of effort for matrix-product-state approaches.
To fast-forward clinical translation of CAL, the North American Imaging in Multiple Sclerosis Cooperative developed a Consensus Statement, which provides guidance for the radiological definition and measurement of CAL.
