Our proposal consists in a quantum sensor based on a superconduc:ng resonator. The working principle is based on the exponential growth of the susceptibility in proximity of a critical phase transition, where the system quickly switches from the vacuum state to a strong emission of easily detectable microwave signals, in response to extremely weak electromagnetic signals. The sensor can detect microwave and radiowave signals, with single-photon resolu:on.

The metasurface optomechanical modulator is a device designed to modulate the amplitude, phase and polarization of a beam of electromagnetic radiation, independently, or simultaneously, according to prescribed paths in the parameter space (for example, as regards polarization, paths on the Poincaré sphere). The concept of our device can be applied to the entire spectrum of electromagnetic waves: from radio frequency, to microwaves (GHz), to millimeter waves (THz), to far and near infrared radiation, and to visible light.

The technology concerns planar optical antennas composed of thin metal films and dielectric materials for the efficient direction of the light emitted by light sources, such as fluorescent molecules and bio-markers. They consist of a reflector layer, adjacent to the substrate, and a director, semi-reflective, between which the emitter is positioned, integrated into a homogeneous dielectric layer.
