We describe a digital microwave platform called Presto, designed for measurement and
control of multiple quantum bits (qubits) and based on the third-generation radio-frequency …

We study the multipartite entanglement generation and dynamics of three giant atoms
coupling to a one-dimensional waveguide. By solving the time-delayed differential …

We have developed a theory of parametric photon generation in the waveguides coupled to
arrays of quantum emitters with temporally modulated resonance frequencies. Such …

We have calculated and measured the effect of two ac excitations on the quantum shot noise
of a tunnel junction. Using a phase-sensitive detection, we demonstrate that the junction …

Universal control over a bosonic degree of freedom is key in the quest for quantum-based
technologies. Such universal control requires however the ability to perform demanding non …

The ability to generate entangled states of light is a key primitive for quantum communication
and distributed quantum computation. Continuously driven sources, including those based …

We derive a set of genuine multi-mode entanglement criteria for second moments of the
quadrature operators. The criteria have a common form of the uncertainty relation between …

We analyse the entanglement in a model Josephson photonics system in which a dc voltage-
biased Josephson junction couples a collection of cavity modes and populates them with …

Control over the coupling between multiple modes of a frequency comb is an important step
toward measurement-based quantum computation with a continuous-variable system. We …

Quantum resources play a pivotal role in the emerging field of quantum technologies,
underpinning the development of quantum computers, communication systems, and sensing …
