ENTCALC: Toolkit for calculating geometric entanglement in multipartite quantum systems
Piotr Masajada, Aby Philip, Alexander Streltsov
We present entcalc, a Python and MATLAB package for estimating the geometric entanglement of multipartite quantum states. The package operates as follows: given a multipartite quan…
Limiting one-way distillable secret key via privacy testing of extendible states
Vishal Singh, Karol Horodecki, Aby Philip +1
The notions of privacy tests and -extendible states have both been instrumental in quantum information theory, particularly in understanding the limits of secure communication.…
Robustness of quantum data hiding against entangled catalysts and memory
Aby Philip, Alexander Streltsov
Quantum data hiding stores classical information in bipartite quantum states that are, in principle, perfectly distinguishable, yet remain almost indistinguishable without access t…
Analytic Rényi Entropy Bounds for Device-Independent Cryptography
Thomas A. Hahn, Aby Philip, Ernest Y. -Z. Tan +1
Device-independent (DI) cryptography represents the highest level of security, enabling cryptographic primitives to be executed safely on uncharacterized devices. Moreover, with su…
Digital Quantum Simulations of the Non-Resonant Open Tavis-Cummings Model
Aidan N. Sims, Dhrumil Patel, Aby Philip +4
The open Tavis--Cummings model consists of quantum emitters interacting with a common cavity mode, accounts for losses and decoherence, and is frequently explored for quantum i…
Device-Independent Certification of Multipartite Distillable Entanglement
Aby Philip, Mark M. Wilde
Quantum networks consist of various quantum technologies, spread across vast distances, and involve various users at the same time. Certifying the functioning and efficiency of the…
