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 …

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

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 ability to control multidimensional quantum systems is central to the development of
advanced quantum technologies. We demonstrate a multidimensional integrated quantum …

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

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

We present designs for scalable quantum computers composed of qubits encoded in
aggregates of four or more Majorana zero modes, realized at the ends of topological …

Quantum computers promise dramatic advantages over their classical counterparts, but the
source of the power in quantum computing has remained elusive. Here we prove a …

Quantum information carriers, just like most physical systems, naturally occupy high-
dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high …

Recent results on the non-universality of fault-tolerant gate sets underline the critical role of
resource states, such as magic states, to power scalable, universal quantum computation …
