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…
Counterfactual quantum measurements
Ingita Banerjee, Kiarn T. Laverick, Howard M. Wiseman
Counterfactual reasoning plays a crucial role in exploring hypothetical scenarios, by comparing some consequent under conditions identical except as results from a differing antece…
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…
Post-processed estimation of quantum state trajectories
Soroush Khademi, Jesse J. Slim, Kiarn T. Laverick +5
Weak quantum measurements enable real-time tracking and control of dynamical quantum systems, producing quantum trajectories -- evolutions of the quantum state of the system condit…
