Interested in moving towards modular laser setups, but don't want to spend your days in CAD? PyOpticL let's you define beampaths in python code and automagically generates CAD files for a baseplate that all your optomechanics just drop onto.

⚛ Can small quantum computers accelerate AI on massive classical data? Yes! I am absolutely thrilled to share our new work proving *honest* exponential quantum advantages in broadly applicable classical tasks. 🧵👇 Paper: arxiv.org/abs/2604.07639 Blog: quantumfrontiers.com/2026/04…

Big news from our department! 🚀 Prof. Daniel Blumenthal and his group, in collaboration with @UMassAmherst, have demonstrated a chip-scale stabilized laser for trapped-ion quantum systems. 🔗bit.ly/4vgq7Wt @UCSBengineering @ucsantabarbara

Reminder Quantum computing could soon fit on a chip, thanks to this breakthrough "Researchers just built a chip scale 674 nm stabilized laser with ultra high stability (~8.8 × 10⁻¹³), all on a silicon photonics platform." "It runs at room temperature and can control trapped-ion qubits, handling preparation, manipulation, and measurement." "This means quantum systems no longer need massive lab setups." We’re moving toward compact, scalable, real world quantum technology.

#UCSB and UMass Amherst researchers have demonstrated a tiny laser, making progress toward portable quantum technology. By shrinking lasers and optical components that power experiments, quantum circuits become compact and more accessible. Full story: ow.ly/jwzg50YBRm9
