A Quadratic Speedup in the Optimization of Noisy Quantum Optical Circuits
Robbe De Prins, Yuan Yao, Anuj Apte +1
Linear optical quantum circuits with photon number resolving (PNR) detectors are used for both Gaussian Boson Sampling (GBS) and for the preparation of non-Gaussian states such as…
Parallelizable Synthesis of Arbitrary Single-Qubit Gates with Linear Optics and Time-Frequency Encoding
Antoine Henry, Ravi Raghunathan, Guillaume Ricard +5
We propose novel methods for the exact synthesis of single-qubit unitaries with high success probability and gate fidelity, considering both time-bin and frequency-bin encodings. T…
Riemannian optimization of photonic quantum circuits in phase and Fock space
Yuan Yao, Filippo Miatto, Nicolás Quesada
We propose a framework to design and optimize generic photonic quantum circuits composed of Gaussian objects (pure and mixed Gaussian states, Gaussian unitaries, Gaussian channels,…
Natural Gradient Optimization for Optical Quantum Circuits
Yuan Yao, Pierre Cussenot, Richard A. Wolf +1
Optical quantum circuits can be optimized using gradient descent methods, as the gates in a circuit can be parametrized by continuous parameters. However, the parameter space as se…
Full-mode Characterisation of Correlated Photon Pairs Generated in Spontaneous Downconversion
Alessio D'Errico, Felix Hufnagel, Filippo Miatto +2
Spontaneous parametric downconversion is the primary source to generate entangled photon pairs in quantum photonics laboratories. Depending on the experimental design, the generate…
Encoding strongly-correlated many-boson wavefunctions on a photonic quantum computer: application to the attractive Bose-Hubbard model
Saad Yalouz, Bruno Senjean, Filippo Miatto +1
Variational quantum algorithms (VQA) are considered as some of the most promising methods to determine the properties of complex strongly correlated quantum many-body systems, espe…
Fast differentiable evolution of quantum states under Gaussian transformations
Yuan Yao, Filippo M. Miatto
In a recent work we presented a recursive algorithm to compute the matrix elements of a generic Gaussian transformation in the photon-number basis. Its purpose was to evolve a quan…
Two-photon interference: the Hong-Ou-Mandel effect
FrédÉric Bouchard, Alicia Sit, Yingwen Zhang +5
Nearly 30 years ago, two-photon interference was observed, marking the beginning of a new quantum era. Indeed, two-photon interference has no classical analogue, giving it a distin…
Growing Random Graphs with Quantum Rules
Hamza Jnane, Giuseppe Di Molfetta, Filippo M. Miatto
Random graphs are a central element of the study of complex dynamical networks such as the internet, the brain, or socioeconomic phenomena. New methods to generate random graphs ca…
Hong-Ou-Mandel interference of unconventional temporal laser modes
Sascha Agne, Jeongwan Jin, Katanya B. Kuntz +3
The Hong-Ou-Mandel (HOM) effect ranks among the most notable quantum interference phenomena, and is central to many applications in quantum technologies. The fundamental effect app…
Fast optimization of parametrized quantum optical circuits
Filippo M. Miatto, Nicolás Quesada
Parametrized quantum optical circuits are a class of quantum circuits in which the carriers of quantum information are photons and the gates are optical transformations. Classicall…
Recursive multivariate derivatives of of arbitrary order
Filippo M. Miatto
High-order derivatives of nested functions of a single variable can be computed with the celebrated Faà di Bruno's formula. Although generalizations of such formula to multiple var…
Graphical Calculus for products and convolutions
Filippo M. Miatto
Graphical calculus is an intuitive visual notation for manipulating tensors and index contractions. Using graphical calculus leads to simple and memorable derivations, and with a b…
Hamiltonians for one-way quantum repeaters
Filippo M. Miatto, Michael Epping, Norbert Lutkenhaus
Quantum information degrades over distance due to the unavoidable imperfections of the transmission channels, with loss as the leading factor. This simple fact hinders quantum comm…
Giant weak value amplification with chirped waveforms
Filippo M Miatto
Weak value amplification is a classical phenomenon that can enhance the sensitivity of a measurement through clever use of interference. The most well-known paradigm of weak value…
Theory of multiplexed photon number discrimination
Filippo. M. Miatto, Akbar Safari, Robert W. Boyd
Although some non-trivial photon number resolving detectors exist, it may still be convenient to discriminate photon number states with the method of multiplexed detection. Multipl…
Sub-fidelity as a measure of irreversibility of decoherence
Filippo M. Miatto, Kevin Piche, Thomas Brougham +1
Quantum correlations between two systems can be impaired by the presence of an environment, as it can make systems decohere. We wish to evaluate how much coherence has been irrever…
The Quantum Hilbert Hotel
Václav Potocek, Filippo M. Miatto, Mohammad Mirhosseini +5
In 1924 David Hilbert conceived a paradoxical tale involving a hotel with an infinite number of rooms to illustrate some aspects of the mathematical notion of "infinity". In contin…
Recovering full coherence in a qubit by measuring half of its environment
Filippo M. Miatto, Kevin Piché, Thomas Brougham +1
When quantum systems interact with the environment they lose their quantum properties, such as coherence. Quantum erasure makes it possible to restore coherence in a system by meas…
Projective filtering of a single spatial radiation eigenmode
A. M. Pérez, P. R. Sharapova, S. S. Straupe +4
Lossless filtering of a single coherent (Schmidt) mode from spatially multimode radiation is a problem crucial for optics in general and for quantum optics in particular. It become…
Divergence of an orbital-angular-momentum-carrying beam upon propagation
Miles J. Padgett, Filippo M. Miatto, Martin Lavery +2
There is recent interest in the use of light beams carrying orbital angular momentum (OAM) for creating multiple channels within free-space optical communication systems. One limit…
The optimal bound of quantum erasure with limited means
Filippo M. Miatto, Kevin Piché, Thomas Brougham +1
In practical applications of quantum information science, quantum systems can have non-negligible interactions with the environment, and this generally degrades the power of quantu…
The duality principle in the presence of postselection
Jonathan Leach, Eliot Bolduc, Filippo. M. Miatto +3
The duality principle, a cornerstone of quantum mechanics, limits the coexistence of wave and particle behaviours of quantum systems. This limitation takes a quantitative form when…
A "fair sampling" perspective on an apparent violation of duality
Eliot Bolduc, Jonathan Leach, Filippo M. Miatto +2
In the event in which a quantum mechanical particle can pass from an initial state to a final state along two possible paths, the duality principle states that "the simultaneous ob…
