Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

This topical review introduces the theoretical and experimental advances in continuous-
variable (CV)—ie qumode-based in lieu of qubit-based—large-scale, fault-tolerant quantum …

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 unique features of quantum theory offer a powerful new paradigm for information
processing. Translating these mathematical abstractions into useful algorithms and …

It is control that turns scientific knowledge into useful technology: in physics and engineering
it provides a systematic way for driving a dynamical system from a given initial state into a …

A logical qubit is a two-dimensional subspace of a higher dimensional system, chosen such
that it is possible to detect and correct the occurrence of certain errors. Manipulation of the …

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 …

Quantum computers solve ever more complex tasks using steadily growing system sizes.
Characterizing these quantum systems is vital, yet becoming increasingly challenging. The …

High-dimensional encoding of quantum information provides a way of transcending the
limitations of current approaches to quantum communication, which are mostly based on the …

The use of d-level qudits instead of two-level qubits can largely increase the power of
quantum logic for many applications, ranging from quantum simulations to quantum error …
