The quantum enigma machine developed by the researchers consists of three parts - a machine that generates photons, a spatial light modulator (SLM) that alters the amplitude and tilt of individual photons and also scrambles its wavefront, and an 8 by 8 photon detecting nanowire array.
A small liquid crystal display called a spatial light modulator imparted a particular twist in the beam--say, one twist.
It should be possible to transport sound energy around corners by manipulating the phase of acoustic waves with a device equivalent to a spatial light modulator, he said.
