Industry-ready spin-photon interfaces for hybrid photonic quantum computing
Hêlio Huet, Hubert Lam, Thibaut Pollet +45
The paper demonstrates large‑scale, foundry‑compatible semiconductor quantum‑dot devices that act as efficient spin‑photon interfaces, achieving near‑unity photon purity, multi‑pho…
Energetics of non-Gaussianity in single mode cavities
Sahil Sardar Jafar, Kian Hwee Lim, Kiarn T. Laverick +3
Non-Gaussian states play a central role in quantum technologies, making the ability to quantify non-Gaussianity essential. We introduce an energetic framework to characterize non-G…
Optimizing Wigner Negativity in Scattering Processes Using Energetic Cost Functions
Kian Hwee Lim, Kiarn T. Laverick, Sahil Sardar Jafar +3
Wigner negativities (WNs) are key signatures of non-Gaussian bosonic states and essential resources for quantum technologies. We study their generation in the scattering of coheren…
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…
Superradiant decay in non-Markovian Waveguide Quantum Electrodynamics
Rosa Lucia Capurso, Giuseppe Calajó, Simone Montangero +5
An array of initially excited emitters coupled to a one-dimensional waveguide exhibits superradiant decay under the Born-Markov approximation, manifested as a coherent burst of pho…
Non-Markovian dynamics of generation of bound states in the continuum via single-photon scattering
Giuseppe Magnifico, Maria Maffei, Domenico Pomarico +4
The excitation of bound states in the continuum (BICs) in two- or multi-qubit systems lies at the heart of entanglement generation and harnessing in Waveguide Quantum Electrodynami…
