- Abstract: Higher dimensional Hilbert space along with ability to control multiple
degrees of freedom of photon and entangle them has enabled new quantum
protocols for various quantum information processing applications. Here, we
propose a scheme to generate and control polarization-path frequency
entanglement using the operative elements required to implement a
polarization-controlled quantum walk in the path(position) space and frequency
domain. Hyperentangled states manifests in the controlled dynamics using an
interferometric setup where half-wave plates, beam-splitters and frequency
shifters such as those based on the electro-optic effect are used to manipulate
the polarization, path and frequency degrees of freedom respectively. The
emphasis is on utilizing the polarization to influence the movement to a
specific value in the frequency and position space. Negativity between the
subspaces is calculated to demonstrate the controllability of the entanglement
between them. Progress reported with experimental demonstration of realization
of quantum walk using quantum states of light makes quantum walks a practical
approach to generate hyperentangled states.
