13-level Qudit Measurement Demonstrated in Trapped Ions
Abstract: Qudits are an interesting alternative to qubits for a number of algorithmic reasons, but for trapped ions they could be a path for scaling. Ion traps are running into limitations on the number of qubits they can confine in a single trap, and using more of the computational space available in the ions to make qudits is an attractive solution. We have proposed using trapped ion qudits in a previous paper, developing all of the necessary quantum information protocols for their implementation. Here, we present an experimental result of a 13-level qudit measurement with a fidelity of 91.3%. The protocol can be used to measure up to a 25-level qudit in barium. The error scaling is not inherent to the dimension of the qudit, so we can envision going to higher dimensions without a significant increase in error.
