New AI method predicts properties of quantum orbitals with intuitive speed
From the University of Chicago: One of the primary research goals of scientist Laura Gagliardi's group at the University of Chicago has been to automate the analysis of molecular orbitals — the quantum-level electron structures critical for understanding bonding and reactivity. This critical area of research is now receiving a powerful boost from research on the Cartesian Equivariant Orbital Network, a new AI tool developed by Daniel King, now a fellow at the University of California, Berkeley.

Spin qubits: sensing heartbeats to dark matter — with Argonne National Laboratory
From the Post Quantum World podcast: The word “foundry” might make you think of large machines pouring metal into molds, but Argonne National Lab has a Quantum Foundry that implants individual atoms, like silicon, into materials such as diamond. The resulting spin qubits are optically active and can use photons to communicate. We can expect spin qubits to help interconnect systems, which could help us achieve distributed quantum computing, but they also could be used for everything from room-temperature biological sensors to durable, space-based dark matter detectors. Join host Konstantinos Karagiannis for a cosmic chat with Benjamin Pingault from Argonne National Laboratory. Read More

Tuning into quantum sounds
From Caltech: Researchers at Caltech and Stanford University, including Stanford's Amir Safavi-Naeini, create tiny vibrating devices that can naturally display quantum behavior without needing an external quantum circuit. By harnessing microscopic defects already present in the material, the team achieved single-phonon nonlinear effects that could enable simpler quantum sensors capable of detecting and studying individual molecules with extraordinary sensitivity.
