Qudits vs. qubits : Conditions on Gate Efficiency

One of the big challenges in the field of quantum computing is to increase computing capacity by increasing the number of qubits. Scientists are therefore exploring an alternative called qudits, which are similar to qubits but with more than two available levels. However, due to these additional levels, they may have more paths vulnerable to errors. The objective of the study is therefore to investigate whether qudits are still competitive with qubits for handling errors arising from the environment. The study showed that qudits can be a promising option for quantum information processing in the future, especially if associated with specialized error correction methods.

    Today, multiple new platforms are implementing qudits, $d$-level quantum bases of information, for Quantum Information Processing (QIP). It is therefore crucial to study their efficiencies for QIP compared to more traditional qubit platforms. We present a comparative study of the infidelity scalings of a qudit and $n$-qubit systems, both with […]
