CLEO®/Europe-EQEC 2017 shock waves' squeezing

Summary form only given. Squeezed states are quantum states of light, which recently proved to play an important role in modern physics due to their connection with quantum information and their employment in quantum computation and gravitational wave detection [1,2].Here we show that squeezed states appear during the development of a classical optical shock phenomenon. Dispersive shock waves emerge during the wave propagation when a discontinuity in their derivative arises as a consequence of an abrupt jump in some of the quantities involved. These waves are singular solutions of hyperbolic partial differential equations, which describe a wide variety of wave-like phenomena in physics, ranging from fluido-dynamics to plasmas and Bose-Einstein condensation (see e.g. [4,5]).
