← ScienceIn polarizing beam splitters in optical quantum computers, which outcome occurs when photons pass through misaligned axes?
A)Elliptical polarization state emerges✓
B)Improved quantum state fidelity
C)Increased optical path length
D)Reduced susceptibility to decoherence
💡 Explanation
When photon polarization aligns imperfectly with a splitter's axis, the **Malus's Law** mechanism dictates only a fraction transmits, which generates elliptical polarization because the orthogonal components interfere, therefore, ellipticity dominates when misalignment increases rather than quantum fidelity under ideal conditions.
