Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. This milestone demonstrates a pathway to large error-corrected quantum computers, maintaining qubit superposition for about 13 seconds with 99.98% manipulation accuracy.
This article details a DIY atomic force microscope built from mostly junk parts. It utilizes a laser-based deflection reading system instead of traditional piezo motors, achieving 35-um resolution with readily available materials. The project focuses on simplicity and cost-effectiveness, making it suitable for educational purposes.
I bought one of these at Weird Stuff Warehouse
