One light wave travels down the vertical arm, and the other travels down the horizontal arm. A mirror at the end of each arm reflects the light waves, which travel back to meet at the beam splitter.

This involves the variable properties of light waves. These can be, for example, the amplitude or phase, i.e. the oscillation behaviour of waves, which are important for the targeted manipulation ...

A research team has now used classical mechanics to explain two particular properties of light: polarization and entanglement. The first is the ability of light waves to have an orientation – a ...

Scientists at Paderborn University have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors ...
