PPT Entanglement with Correlated Catalysis: Monotones and Irreversibility
Jingsong Ao, Aby Philip, Alexander Streltsov
Quantum catalysts can overcome otherwise impossible quantum state transformations without being consumed, and allowing them to become correlated with the output makes this assistan…
Entanglement battery and entanglement catalyst in local state discrimination problems
Saronath Halder, Aby Philip, Alexander Streltsov
In this work, we study the limitations and advantages of using entanglement battery and entanglement catalyst in local state discrimination problems. We consider both cases of such…
Witness robustness: An operational quantifier of measurement resources via free state discrimination
Jingsong Ao, Aby Philip, Alexander Streltsov
We introduce the witness robustness of quantum measurements, a resource quantifier whose admissible noise consists of tuples of free-state witnesses rather than physical measuremen…
Resourcefulness without Resource: Geometric Origins and Robustness
Jingsong Ao, Aby Philip, Alexander Streltsov
A prevailing intuition holds that quantum protocols using only free states confer no operational advantage. This intuition is contradicted by free-state discrimination gaps in whic…
Asymptotic Limits of Entanglement Transmission
Piotr Masajada, Aby Philip, Alexander Streltsov
Reliable distribution of quantum entanglement over long distances is a central challenge in quantum information science, fundamentally limited by decoherence in noisy communication…
Advantage of flexible catalysis for entanglement and quantum thermodynamics
Jingsong Ao, Aby Philip, Alexander Streltsov
Understanding the fundamental limits of state convertibility is crucial for establishing the boundaries of quantum information processing and thermodynamic efficiency. While auxili…
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…
Optimality of universal conclusive entanglement concentration protocols
Alexandre C. Orthey, Aby Philip, Tulja Varun Kondra +1
Entanglement concentration is essential for quantum technologies, yet rigorous bounds on the success probability for universal protocols (those requiring no prior knowledge about 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…
Schrödinger as a Quantum Programmer: Estimating Entanglement via Steering
Aby Philip, Soorya Rethinasamy, Vincent Russo +1
Quantifying entanglement is an important task by which the resourcefulness of a quantum state can be measured. Here, we develop a quantum algorithm that tests for and quantifies th…
