Qudit is a multi-level computational unit alternative to the conventional 2-level qubit.
Compared to qubit, qudit provides a larger state space to store and process information, and …

Most quantum computers use binary encoding to store information in qubits—the quantum
analogue of classical bits. Yet, the underlying physical hardware consists of information …

The dynamics of quantum information in strongly interacting systems, known as quantum
information scrambling, has recently become a common thread in our understanding of …

Multipartite entanglement is one of the core concepts in quantum information science with
