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 …

Multi-level (qudit) entangled photon states are a key resource for both fundamental physics
and advanced applied science, as they can significantly boost the capabilities of novel …

Controlling and programming quantum devices to process quantum information by the unit
of quantum dit, ie, qudit, provides the possibilities for noise-resilient quantum …

Taking advantage of quantum mechanics for executing computational tasks faster than

Optical quantum states based on entangled photons are essential for solving questions in
fundamental physics and are at the heart of quantum information science. Specifically, the …

We describe a generalization of the cluster-state model of quantum computation to
continuous-variable systems, along with a proposal for an optical implementation using …

The recognition of the key role entanglement plays in the understanding of the radical
departure of quantum from classical physics came historically remarkably late. In the early …

With the advent of quantum technologies comes the requirement of building quantum
components able to store energy to be used whenever necessary, ie, quantum batteries. In …

We propose families of protocols for magic-state distillation—important components of fault-
tolerance schemes—for systems of odd prime dimension. Our protocols utilize quantum …

Symmetry-protected topological phases (SPTs) have universal degeneracies in the
entanglement spectrum in one dimension. Here we formulate this phenomenon in the …
