Quantum Linear Optics via String Diagrams

Giovanni de Felice, Bob Coecke

We establish a formal bridge between qubit-based and photonic quantum computing. We do this by defining a functor from the ZX calculus to linear optical circuits. In the process we…

Opportunities and Limitations in Broadband Sensing

Anthony M. Polloreno, Jacob L. Beckey, Joshua Levin +5

We consider estimating the magnitude of a monochromatic AC signal that couples to a two-level sensor. For any detection protocol, the precision achieved depends on the signal's fre…
