Dielectric metasurfaces for quantum weak measurements

Metasurfaces have shown extraordinary abilities to manipulate the phase and polarization of light and thus hold great promise for applications in photonics and optoelectronics. Here, we propose a unique application of the dielectric metasurface for quantum weak measurements. In our scheme, the dielectric metasurface introduces a tiny phase gradient in the procedure of measurements and keeps the measured system almost undisturbed. The dielectric metasurface may improve and simplify already existing schemes in quantum weak measurements and thereby provide potential applications in precise measurements of phase, polarization, and frequency of light.
