Latent information carried by photons enables super-precise spectrometer

Two researchers at the University of Warsaw developed a quantum-inspired super-resolving spectrometer for short pulses of light. The device designed in the Quantum Optical Devices Lab at the Centre for Quantum Optical Technologies, Centre of New Technologies and Faculty of Physics UW offers over a two-fold improvement in resolution compared to standard approaches. In the future, it can be miniaturized on a photonic chip and applied in optical and quantum networks as well as in spectroscopic studies of matter.
