- Abstract: Multipartite high-dimensional entanglement presents different physics from
multipartite two-dimensional entanglement. However, how to prepare multipartite
high-dimensional entanglement is still a challenge with linear optics. In this
paper, a multiphoton GHZ state with arbitrary dimensions preparation protocol
is proposed in optical systems. In this protocol, we use auxiliary
entanglements to realize a high-dimensional entanglement gate, so that
high-dimensional entangled pairs can be connected into a multipartite
high-dimensional GHZ state. Specifically, we give an example of using photons'
path degree of freedom to prepare a 4-particle 3-dimensional GHZ state. Our
method can be extended to other degrees of freedom and can generate arbitrary
GHZ entanglement in any dimension.

Laguerre-Gaussian modes, which carry orbital angular momentum (OAM), are commonly exploited to engineer high-dimensional entangled quantum states.
For Hilbert spaces with d>2, maximally entangled states (MESs) help to improve the capacity and security of quantum communication protocols.
We formalize how the spatial distribution of the pump beam and the nonlinear profile of the crystal can be simultaneously utilized to generate MES.

We build two-dimensional (2D) systems with spectra identical to that of one-dimensional (1D) Jx lattices.
While exhibiting different dynamics, these 2D systems retain the key imaging and state transfer properties of the 1D Jx lattice.
Our method extends to other systems with separable spectra, facilitates experimental fabrication, and may increase robustness to fabrication imperfections in large-scale photonic circuits.

Quantum imaging is well-suited to study sensitive samples which require low-light conditions, like biological tissues.
In this context, interaction-free measurements (IFM) allow us infer the presence of an opaque object without the photon interacting with the sample.
Here we extend the IFM imaging schemes to multi-pixel, semi-transparent objects, by encoding the information about the pixels into an internal degree of freedom.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
