Description
In the current stage of its evolution, Quantum Information Processing is
following the precedent set by classical computing and generally encodes information in binary form, thus relying on so-called qubits. For many of the systems used to process this quantum information, this is however a rather artificial constraint, limiting the Hilbert space available for computation and introducing leakage errors that slip through the most common error correction schemes. Going from qubits to qudits, non-binary logical base states, to leverage a larger Hilbert space for computation is therefore one path towards building more powerful and reliable Quantum Information Processors that can be used to solve real-world problems. We use trapped Calcium ions to encode information in higher-dimensional qudits up to d = 7, demonstrate comparable performance to a qubit-based processor and set out to build a new experimental setup dedicated exclusively to QIP with trapped Calcium qudits. This will enable us to carry out multiple-different entanglement gates on qudits, reducing the experimental overhead required when entangling higher-dimensional systems.
