Abstract: Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown here that these effects can also occur in cholesteric liquid crystals in the presence of an applied magnetic field. The nature of these effects as well as the conditions for their observation are analysed.<br />Comment: Correction: due to a sign error, the potential in the previous version was minimised around a maximum instead of a minimum. This is corrected in the current version. To be able to observe the same effects, cholesteric liquid crystals were considered instead of plain nematics. Figures depicting the potential and the effects of squeezing were added. 17 pages, 4 figures
