Led by a research team of scientists from the University of Nottingham’s School of Physics and Astronomy, the study measured the brainwaves of two-year-old children using a quantum-based magnetoencephalography (MEG) scanner, providing the clearest picture of early childhood brain development so far. This wearable brain scanner was utilized to map the electrical activity of the brain. This work opens up new possibilities for tracking how critical early childhood developmental events alter brain function and for studying neurodevelopmental disorders such as autism.

Quantum infrastructure software developer Q-CTRL announced yesterday that a new study reveals their performance management technology can achieve more than a 4x improvement in solving quantum optimization problems on IBM's 127-qubit quantum computer. The outperforms quantum annealers and trapped ion technologies, with a likelihood of returning correct results 1500 times higher than annealers. This signifies that we can now achieve significant practical value on utility-scale quantum computers.

Quantinuum announced yesterday that the number of fully connected qubits of its flagship product, the System Model H2 quantum computer, has increased from 32 to 56. It also released a research result achieved through collaboration with partners including JPMorgan Chase. They used the H2-1 quantum processor to solve the problem of random circuit sampling and measured the quality of their results through a suite of benchmark tests.

Researchers from the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, collaborating with Yokohama National University, Tohoku University, and NEC Corporation, have proposed and successfully demonstrated a new method that can control multiple qubits via a single cable using microwave multiplexing technology at low temperature. The researchers said that this circuit has the potential to increase the density of microwave signals per cable by approximately 1,000 times, thereby increasing the number of controllable qubits significantly.
