If I'm given a photon polarized at some unknown angle, can I rotate it by 90 degrees (or by an arbitrary angle)?

Photon polarization refers to the orientation of a photon's electromagnetic field as it travels through space. It can be described as either linear or circular, depending on the direction of the field relative to the photon's direction of travel.
A photon's polarization can be rotated by passing it through a material with certain optical properties, such as a polarizing filter or a crystal. These materials can change the direction of the photon's electric field, resulting in a rotation of polarization.
Rotating photon polarization is important in many applications, including telecommunications, quantum computing, and optical imaging. It allows for the manipulation and control of light, which is essential for these technologies to function.
Yes, all types of photons, including those from visible light, radio waves, and X-rays, can be rotated 90 degrees by passing them through the appropriate materials. However, the efficiency of polarization rotation may vary depending on the type of photon.
One example of rotating photon polarization is in 3D movie glasses, where the lenses are coated with a special material that rotates the polarization of light to create the illusion of depth. Another example is in satellite communication, where polarizing filters are used to transmit and receive signals with different polarizations to reduce interference.
