Experimental Demonstration of a Quantum-Optimal Coronagraph Using Spatial Mode Sorters
Nico Deshler, Itay Ozer, Amit Ashok +1
Deep sub-diffraction exoplanet discovery currently lies beyond the reach of state-of-the-art direct imaging coronagraphs, which typically have an inner working angle larger than th…
