infrared spectroscopy doesn't 'touch' the qbit using photon polarization...:
Infrared spectroscopy is a technique that uses infrared light to measure the molecular vibrations of a sample 12. Qubits are quantum systems that can have two possible values, such as spin up and spin down, and can also be in a superposition of both 34.

The effect of infrared spectroscopy on qubit state depends on the type of qubit and the frequency of the infrared light. For example, if the qubit is based on the spin of an electron, and the infrared light has a frequency that matches the energy difference between the spin states, then the infrared light can induce transitions between the spin states and change the qubit state . However, if the qubit is based on the polarization of a photon, and the infrared light has a different polarization than the qubit, then the infrared light will not affect the qubit state .
