Promise and Challenges of Distimation
Joshua Carlo A. Casapao, Ananda G. Maity, Naphan Benchasattabuse +4
Estimating the quality of raw entangled states and distilling high-fidelity entanglement traditionally require two separate link-layer protocols in a quantum network stack, each co…
Linear Optical Schemes to Postselect High-Dimensional Dicke States
Daniel Bhatti, William J. Munro, Seungbeom Chin
Multipartite entanglement is an essential quantum resource for various distributed quantum applications. One promising method for preparing multipartite entanglement is to interfer…
Boosting the performance of a Lipkin-Meshkov-Glick quantum battery via symmetry-breaking quenches or a single-mode bosonic charger
Le Bin Ho, Duc Tuan Hoang, Tran Duong Anh-Tai +2
We explore the operation of quantum batteries in the Lipkin-Meshkov-Glick (LMG) model, when they are charged either through a sudden quench in the magnetic field strength or by cou…

Zhuo Chen, Wenhua Qin, Hanyu Ren +5
We report a three-dimensional lumped-element multimode microwave resonator that enables homogeneous collective manipulation and dispersive readout of a macroscopic spin ensemble. B…
Linear Program Witness for Network Nonlocality in Arbitrary Networks
Salome Hayes-Shuptar, Daniel Bhatti, Ana Belen Sainz +1
Network nonlocality extends Bell nonlocality to settings with multiple independent sources and parties. Certifying it in quantum information processing tasks requires suitable witn…
Loophole-free Bell-inequality violation between atomic states in cavity-QED systems mediated by hybrid atom-light entanglement
Pei-Zhe Li, Soumyakanti Bose, Hyunseok Jeong +3
We present a feasible and scalable approach to testing Bell nonlocality and implementing device-independent quantum key distribution (DI-QKD) between distant atomic states in cavit…
Heralded Linear Optical Generation of Dicke States
Minhyeok Kang, Jaehee Kim, William J. Munro +2
Entanglement is a fundamental feature of quantum mechanics and a key resource for quantum information processing. Among multipartite entangled states, Dicke states …
Decoupling local classicality from classical explainability: A noncontextual model for bilocal classical theory and a locally-classical but contextual theory
Sina Soltani, Marco Erba, David Schmid +1
We construct an ontological model for the theory known as bilocal classical theory doi.org/10.1103/PhysRevA.102.052216. To our knowledge, this is only the second time that an ontol…
Application and quantum properties of superpositions of oppositely squeezed states
Hiroo Azuma, William J. Munro, Kae Nemoto
We show that superpositions of oppositely squeezed states -- non-Gaussian Schr{ö}dinger-cat-like states -- exhibit enhanced nonclassical features and provide an entanglement advant…
Quantum Optimal Control for Coherent Spin Dynamics of Radical Pairs via Pontryagin Maximum Principle
Ugur G. Abdulla, Jose H. Rodrigues, Jean-Jacques Slotine
This paper aims to devise the shape of the external electromagnetic field that drives the spin dynamics of radical pairs to a quantum coherent state through maximization of the tri…
On the relation between perspective-neutral, algebraic, and effective quantum reference frames
Julian De Vuyst, Philipp A. Hoehn, Artur Tsobanjan
The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gr…
Collective emission of atomic nanorings around an optical nanofiber
