Industry-ready spin-photon interfaces for hybrid photonic quantum computing
Hêlio Huet, Hubert Lam, Thibaut Pollet +45
Hybrid photonic quantum computers, combining stationary matter qubits and flying photonic qubits, offer an intrinsically networked and resource-efficient route to large-scale, erro…
Energetics of non-Gaussianity in single mode cavities
Sahil Sardar Jafar, Sahil S. Jafar, Kian Hwee Lim +4
Non-Gaussian states are key resources for quantum technologies, making the quantification of non-Gaussianity a fundamental challenge. We introduce an energetic framework for charac…
Optimizing resource allocation for accuracy in noisy variational quantum algorithms
Harshit Verma, Thomas Ayral, Alexia Auffèves +1
For quantum algorithms to achieve their full potential, we need methodologies to optimize them, such as reaching a given output accuracy with minimal resource costs. Here, we devel…
Optimizing Wigner Negativity in Scattering Processes Using Energetic Cost Functions
Kian Hwee Lim, Kiarn T. Laverick, Sahil S. Jafar +3
Wigner negativity is a key resource for quantum technologies but is difficult to optimize in multimode scattering systems. We study the scattering of coherent pulses by a two-level…
Inhomogeneous Light-Matter Coupling as a Resource for Noiseless Quantum Memories
Fumiya Hanamura, Sicheng Bao, Jie Lerk Yoo +2
Inhomogeneous ensembles of two-level systems are central to both fundamental light-matter physics and quantum-network applications. Understanding and optimizing ensemble-based quan…
An Energetic Constraint for Qubit-Qubit Entanglement
Kiarn T. Laverick, Samyak P. Prasad, Pascale Senellart +2
We analyze qubit-qubit entanglement from an energetic perspective and reveal an energetic trade-off between quantum coherence and entanglement. We decompose each qubit internal ene…
Accessing which-path information in the absorption and emission of light by a quantum dot in a Ramsey sequence
I. Maillette de Buy Wenniger, M. Maffei, S. C. Wein +8
We quantify which-path information in the absorption and emission of light by a quantum dot along a Ramsey-like sequence. The quantum dot is excited by two successive classical $π/…
Hamiltonian Benchmark of a Solid-State Spin-Photon Interface for Computation
Tejas Acharya, Loïc Lanco, Olivier Krebs +3
Light-matter interfaces are pivotal for quantum computation and communication. While typically analyzed using single-mode or open-quantum-system approximations, these models often…
Entropic Efficiency of Bayesian Inference Protocols
Nathan Shettell, Alexia Auffèves
Inference is a versatile tool that underlies scientific discovery, machine learning, and everyday decision-making: it describes how an agent updates a probability distribution as p…
Irreversibility of decorrelating processes: an experimental assessment in cavity QED
Guillaume Cœuret Cauquil, Patrice A. Camati, Irénée Frerot +3
Entropy production quantifies the amount of irreversibility of a physical process, leading to fundamental bounds for thermodynamic quantities. It captures the inability to run a ph…
A Retrodictive Approach to Quantum State Smoothing
Mingxuan Liu, Valerio Scarani, Alexia Auffèves +1
Smoothing is a technique for estimating the state of an imperfectly monitored open system by combining both prior and posterior measurement information. In the quantum regime, curr…
The two-spin enigma: from the helium atom to quantum ontology
Philippe Grangier, Alexia Auffeves, Nayla Farouki +2
The purpose of this article is to provide a novel approach and justification of the idea that classical physics and quantum physics can neither function nor even be conceived one w…
Reservoir-Free Decoherence in Flying Qubits
Nicolò Piccione, Léa Bresque, Andrew N. Jordan +2
An effective time-dependent Hamiltonian can be implemented by making a quantum system fly through an inhomogeneous potential, realizing, for example, a quantum gate on its internal…
Energetic footprints of irreversibility in the quantum regime
M. H. Mohammady, A. Aufféves, J. Anders
In classical thermodynamic processes the unavoidable presence of irreversibility, quantified by the entropy production, carries two energetic footprints: the reduction of extractab…
Generation of non-classical light in a photon-number superposition
J. C. Loredo, C. Antón, B. Reznychenko +12
The ability to generate light in a pure quantum state is essential for advances in optical quantum technologies. However, obtaining quantum states with control in the photon-number…
What is quantum in quantum randomness?
Philippe Grangier, Alexia Auffèves
It is often said that quantum and classical randomness are of different nature, the former being ontological and the latter epistemological. However, so far the question of "What i…
