Slow light is a dramatic reduction in the group velocity of light, not the phase velocity. Slow light effects are not due to abnormally large refractive indices, as will be explained below. The simplest picture of light given by classical physics is of a wave or disturbance in the electromagnetic field.
Authors created a stationary light pulse inside the atomic coherent media. [15] In 2009 researchers from Harvard University and MIT demonstrated a few-photon optical switch for quantum optics based on the slow light ideas. [16] Lene Hau and a team from Harvard University were the first to demonstrate stopped light. [17]

If you travelled a year at 95% the speed of light; you'd age one year, and people on Earth would age 3.2 years! But if you were going 50% the speed of light it would only be 1.15 years. The effect ...
Later work based on these experiments led to the transfer of light to matter, then from matter back into light, [3] a process with important implications for quantum encryption and quantum computing. More recent work has involved research into novel interactions between ultracold atoms and nanoscopic-scale systems.

The quantum Zeno effect (also known as the Turing paradox) is a feature of quantum-mechanical systems allowing a particle's time evolution to be slowed down by measuring it frequently enough with respect to some chosen measurement setting. [1] Sometimes this effect is interpreted as "a system cannot change while you are watching it". [2]
