"observe and control quantum phenomena at room temperature on macroscopic scale... minimize thermal noise using cavity mirrors (patterned with crystal-like periodic phononic crystal-like structures) with mechanical oscillator in middle, bouncing light back and forth inside cavity, isolated from environmental noise, enabling subtle quantum deection at room temperature, optically squeezing quantum phenomenon a la Heisenberg's principle... quantum information within large complex quantum states. trapped atom clouds"
