Optimality of Gaussian Entanglement of Formation
Gerardo Adesso
We prove that the entanglement of formation of every two-mode Gaussian state coincides with its Gaussian restriction, solving a longstanding open problem in continuous variable qua…
High-frequency dual-channel lock-in detection via rapidly oscillating driving
Kangze Li, Xu Zhao, Liantuan Xiao +1
Here we propose a general protocol for dual-channel lock-in detection of high-frequency ac signals. We find that the effect of a high-frequency target signal can be modulated throu…
Quantum Lock-In Detection via Successive Adiabatic Evolution
Kangze Li, Siqi Chen, Hao Zhang +3
The paper introduces a quantum lock‑in detection scheme based on successive adiabatic evolution that uses triangular‑wave modulation to eliminate spectral leakage and improve the d…
Fundamental Quality Bound on Optical Quantum Communication
Tobias Rippchen, Ludovico Lami, Gerardo Adesso +1
Sending quantum information reliably over long distances is a central challenge in quantum technology in general, and in quantum optics in particular, since most quantum communicat…
Maximum residual strong monogamy inequality for multiqubit entanglement
Dong-Dong Dong, Xue-Ke Song, Liu Ye +2
We establish two new inequalities, the weighted strong monogamy (WSM) and the maximum residual strong monogamy (MRSM), which sharpen the generalized Coffman-Kundu-Wootters inequity…
Ergotropic characterization of continuous variable entanglement
Beatriz Polo-RodrÃguez, Federico Centrone, Gerardo Adesso +1
Continuous-variable quantum thermodynamics in the Gaussian regime provides a promising framework for investigating the energetic role of quantum correlations, particularly in optic…
