Researchers Craft a New, Simple Recipe for Highly Entangled Quantum States
Insider Brief PRESS RELEASE — Building useful quantum technologies—from sensors to computers—requires generating highly complex entangled states, in which the properties of particles are deeply intertwined. Producing such states has traditionally required complex tools and carefully engineered setups with many parts. Now, researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) […]
How to Benchmark Logical Qubit Claims
Insider Brief As the quantum computing sector has evolved, so has the way performance is measured. Early on, qubit count — the number of quantum bits in a processor — was viewed as a key benchmark. Today, researchers increasingly argue that raw qubit count matters less than the number of logical qubits, which can reliably […]
Why Quantum Computing Companies Are Turning to SPACs
