From what I know about (bi-partite) entanglement, we write the combined Hilbert space as a tensor-product of Hilbert spaces for a particle at ##A## and a particle at ##B##, ie ##\mathcal{H} = \mathcal{H} ^{A} \otimes \mathcal{H} ^{B}##. If the particles share a non-separable state, they are considered to be "entangled".
Is it possible to do this in terms of a single particle but at two instances in time? So: ##\mathcal{H} = \mathcal{H} ^{t_1} \otimes \mathcal{H} ^{t_2}## for ##t_1 < t_2##. If so, are there any published papers that expand on this idea?
Cheers.
