Lately it has been shown that cylindrically polarized modes of light exhibit entanglement between the spatial and polarization degrees of freedom when undergoing quadrature squeezing [1]. This arises from a classical inseparability of the associated fields. Apart from being of fundamental interest, this hybrid entanglement can be used to generate multipartite entangled states for one-way quantum computing which are addressable via the spatial degree of freedom in addition to polarization [2]. We show how hybrid entanglement can be accessed experimentally [3] and give an account of progress towards its verification.
