Accelerated Rydberg electromagnetically induced transparency quantum memory via shortcuts to adiabaticity

Y. Wei, Changcheng Li, Y. M. Liu +3

Electromagnetically induced transparency (EIT) enables coherent light-matter storage, forming the basis of photonic quantum memories that are essential for scalable quantum network…

Looking down the rabbit hole: Towards quantum optimal estimation of surface roughness

Quentin Muller, Tommaso Tufarelli, Madalin Guta +3

Surface roughness is an important quantity to many engineering and precision manufacturing disciplines. In this paper we investigate the problem of estimating the root-mean-square…

Multiphoton Hong-Ou-Mandel Interference Enables Superresolution of Bright Thermal Sources

Aiman Khan, Danilo Triggiani, Vincenzo Tamma

We present a quantum optical scheme for imaging transversely displaced thermal sources of arbitrary intensities by employing multiphoton interference with a reference single-photon…

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…

Equilibrium thermometry in the multilevel quantum Rabi model

Tabitha Doicin, Luis A. Correa, Jonas Glatthard +2

The temperature sensitivity of a probe in equilibrium can be gauged by its thermal quantum Fisher information (QFI). It is known that probes exhibiting degeneracy in their energy-l…

Engineering the non-Hermitian Su-Schrieffer-Heeger model with skin effects in Rydberg atom arrays

J. N. Bai, F. Yang, D. Yan +2

We propose and systematically analyze a practical scheme for implementing a one-dimensional non-Hermitian (NH) Su-Schrieffer-Heeger model using individually addressable Rydberg ato…
