Quantum Information Processing has been predominantly developed using qubits, two level quantum systems, as its fundamental building blocks. However many physical implementations of qubit-based quantum processors actually use multilevel systems, from which only two levels are selected for information encoding. By extending the encoding information in multi-level qudit basis states, one directly expands the Hilbert space available for computation, and promises more efficient compilation with respect to the number of required entangling gates. We experimentally demonstrate an implementation of a native two-qudit entangling gate up to dimension 5 in a trapped-ion system, and we present a new experimental apparatus dedicated for exploring higher dimensional qudit protocols and algorithms up to qudit dimension d=7.
