摘 要：Encoding many qubits in different degrees of freedom(DOFs)of single photons is one of the routes toward enlarging the Hilbert space spanned by a photonic quantum *** photon states(that is,states showing entanglement in multiple DOFs)have demonstrated significant implications for both fundamental physics tests and quantum communication and *** the number of qubits of photonic experiments requires miniaturization and integration of the basic elements,and functions to guarantee the setup stability,which motivates the development of technologies allowing the precise control of different photonic DOFs on a *** demonstrate the contextual use of path and polarization qubits propagating within an integrated quantum *** tested the properties of four-qubit linear cluster states built on both DOFs,and we exploited them to perform the Grover s search algorithm according to the one-way quantum computation *** results pave the way toward the full integration on a chip of hybrid multi-qubit multiphoton states.
