Physicists have been working hard to improve the accuracy of atomic clocks, which are the most precise timing devices currently available. A promising way to achieve higher accuracy is to utilize spin squeezed states in clock atoms.Spin squeezed states are entangled quantum states in which particles work together to counteract their inherent quantum noise. These states provide incredible potential...
The rapid development of photonic integrated circuits (PICs) has combined multiple optical devices and functions on a single chip, completely changing optical communication and computing systems.For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and integration with existing semiconductor manufacturing technologies, despite their limitations in electro-optic ...
