High fidelity spatial mode quantum gates enabled by diffractive neural networks

Scientists have developed a method to construct high-dimensional quantum gates using diffractive neural networks, exhibiting ultrahigh fidelities. They successfully implemented various quantum gates and demonstrated the applicability of their approach by performing complex operations like the Deutsch algorithm.

Helping patients with low income overcome eating disorders

A new study suggests that individuals with low income are frequently misdiagnosed and lack access to effective treatment for eating disorders. Researchers offer guidelines for therapists to make accommodations for these patients, including providing government or local food resources and engaging with local food banks.
