Phase-noise induced many-body interference suppression in Gaussian Boson Sampling
Dario Cilluffo, Matthias Kost, Martin B. Plenio
We develop a Heisenberg-picture tensor-network formulation of collision-free Gaussian Boson Sampling, providing a direct Fock-space expression for output probabilities in terms of…
Heisenberg picture tensor network formalism for optical circuits
Dario Cilluffo, Matthias Kost, Nicola Lorenzoni +1
Tensor network formalisms have emerged as powerful tools for simulating quantum state evolution. While widely applied in the study of optical quantum circuits, such as Boson Sampli…
Commentary on the decomposition of universal multiport interferometers: how it works in practice
Dario Cilluffo
The decomposition of multiport interferometers is a fundamental tool in quantum optics and computing. This note aims to serve as a concise reference for performing the decompositio…
Making Quantum Collision Models Exact
Thibaut Lacroix, Dario Cilluffo, Susana F. Huelga +1
Quantum collision describe open quantum systems through repeated interactions with a coarse-grained environment. However, a complete certification of these models is lacking, as no…
Physically constrained quantum clock-driven dynamics
Lea Lautenbacher, Giovanni Spaventa, Dario Cilluffo +2
Thermal machines are physical systems designed to convert thermal energy into practical work through cyclic state transformations. A key component in such a machine is a clock-equi…
Multimode-cavity picture of non-Markovian waveguide QED
Dario Cilluffo, Luca Ferialdi, G. Massimo Palma +2
We introduce a picture to describe and intrepret waveguide-QED problems in the non-Markovian regime of long photonic retardation times resulting in delayed coherent feedback. The f…
Controlling Markovianity with Chiral Giant Atoms
Federico Roccati, Dario Cilluffo
Giant artificial atoms are promising and flexible building blocks for the implementation of analog quantum simulators. They are realized via a multi-local pattern of couplings of t…
An operational definition of quantum information scrambling
Gabriele Lo Monaco, Luca Innocenti, Dario Cilluffo +3
Quantum information scrambling (QIS) is a characteristic feature of several quantum systems, ranging from black holes to quantum communication networks. While accurately quantifyin…
Quantum scrambling via accessible tripartite information
Gabriele Lo Monaco, Luca Innocenti, Dario Cilluffo +3
Quantum information scrambling (QIS), from the perspective of quantum information theory, is generally understood as local non-retrievability of information evolved through some dy…
Simulating Gaussian Boson Sampling with Tensor Networks in the Heisenberg picture
Dario Cilluffo, Nicola Lorenzoni, Martin B. Plenio
Although the Schr{ö}dinger and Heisenberg pictures are equivalent formulations of quantum mechanics, simulations performed choosing one over the other can greatly impact the comput…
Statistical time-domain characterization of non-periodic optical clocks
Dario Cilluffo
Measuring time means counting the occurrence of periodic phenomena. Over the past centuries a major effort was put to make stable and precise oscillators to be used as clock regula…
Microscopic biasing of discrete-time quantum trajectories
Dario Cilluffo, Igor Lesanovsky, Giuseppe Buonaiuto +5
We develop a microscopic theory for biasing the quantum trajectories of an open quantum system, which renders rare trajectories typical. To this end we consider a discrete-time qua…
Mechanism of decoherence-free coupling between giant atoms
Angelo Carollo, Dario Cilluffo, Francesco Ciccarello
Giant atoms are a new paradigm of quantum optics going beyond the usual local coupling. Building on this, a new type of decoherence-free (DF) many-body Hamiltonians was shown in a…
Collisional picture of quantum optics with giant emitters
Dario Cilluffo, Angelo Carollo, Salvatore Lorenzo +3
The effective description of the weak interaction between an emitter and a bosonic field as a sequence of two-body collisions provides a simple intuitive picture compared to tradit…
Witnessing non-classicality through large deviations in quantum optics
Dario Cilluffo, Giuseppe Buonaiuto, Salvatore Lorenzo +4
Non-classical correlations in quantum optics as resources for quantum computation are important in the quest for highly-specialized quantum devices. The standard way to investigate…
Quantum jump statistics with a shifted jump operator in a chiral waveguide
Dario Cilluffo, Salvatore Lorenzo, G. Massimo Palma +1
Resonance fluorescence, consisting of light emission from an atom driven by a classical oscillating field, is well-known to yield a sub-Poissonian photon counting statistics. This…
Quantum non-Markovian collision models from colored-noise baths
Dario Cilluffo, Francesco Ciccarello
A quantum collision model (CM), also known as repeated interactions model, can be built from the standard microscopic framework where a system S is coupled to a white-noise bosonic…
