Quantum researchers have dedicated significant efforts to developing superconducting qubits with a sandwich-like
Quantum researchers have dedicated significant efforts to developing superconducting qubits with a sandwich-like "SIS" junction (a), made up of two superconducting layers (Al) separated by an insulator (AlOX). But a new study from Brookhaven Lab demonstrated that qubits with constriction junctions (b) perform comparably to qubits with SIS junctions. Constriction junctions, which lay flat and consist of two superconducting layers connected by a thin superconducting wire, can be manufactured more readily at scale.

As part of the Co-design Center for Quantum Advantage (C2QA), a DOE National Quantum Information Science Research Center led by Brookhaven Lab, scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have demonstrated a qubit, whose architecture is more amenable to mass production can perform comparably to qubits currently dominating the field.

Scientists did a series of mathematical analyses to create a guide for making qubits more easily, ensuring that these key parts of quantum computers can be made reliably and strongly.

Study uncovered earliest evidence of transport technology

Study uncovered earliest evidence transport technology used by ancient settlers

Drag marks reveal how our ancestors moved heavy loads.

Researchers from Bournemouth University discovered early evidence of transport technology used by settlers in the USA over 20,000 years ago at White Sands National Park, New Mexico. They found drag marks from makeshift vehicles called “travois,” made from wooden poles, alongside ancient human footprints. The tracks included single lines, likely from dragging two poles joined at one end, and parallel lines, from poles crossed in the middle.

The quantum processor that redefines computing speed

It is one quadrillion faster than the fastest supercomputer.

Researchers from the University of Science and Technology of China (USTC) have created a superconducting quantum computing prototype called Zuchongzhi-3. This prototype operates with 105 qubits and 182 couplers, making it 1015 times faster than the fastest supercomputer and one million times faster than Google's latest results. This breakthrough marks a significant advancement in quantum computing performance.

MIT Researchers develop improved validation method for more accurate spatial predictions

MIT Improves Spatial Prediction Validation

Researchers at MIT have tackled a perplexing issue in spatial prediction validation, which is critical for fields like weather forecasting and environmental health. Traditional validation methods often fail because they don’t account for the unique characteristics of spatial data, leading to inaccurate forecasts. The research will be presented at the International Artificial Intelligence and Statistics Conference.
