Random access test as an identifier of nonclassicality
Teiko Heinosaari, Leevi Leppäjärvi
Random access codes are an intriguing class of communication tasks that reveal an operational and quantitative difference between classical and quantum information processing. We f…
Best-practice aspects of quantum-computer calculations: A case study of hydrogen molecule
Ivana Miháliková, Martin Friák, Matej Pivoluska +3
Quantum computers are reaching one crucial milestone after another. Motivated by their progress in quantum chemistry, we have performed an extensive series of simulations of quantu…
Self-testing quantum states via nonmaximal violation in Hardy's test of nonlocality
Ashutosh Rai, Matej Pivoluska, Souradeep Sasmal +3
Self-testing protocols enable certification of quantum devices without demanding full knowledge about their inner workings. A typical approach in designing such protocols is based…
The Cost of Improving the Precision of the Variational Quantum Eigensolver for Quantum Chemistry
Ivana Miháliková, Matej Pivoluska, Martin Plesch +3
Quantum computing brings a promise of new approaches into computational quantum chemistry. While universal, fault-tolerant quantum computers are still not available, we want to uti…
Measurement disturbance and conservation laws in quantum mechanics
M. Hamed Mohammady, Takayuki Miyadera, Leon Loveridge
Measurement error and disturbance, in the presence of conservation laws, are analysed in general operational terms. We provide novel quantitative bounds demonstrating necessary con…
Geometric Bloch Vector Solution to Minimum Error Discriminations of Mixed Qubit States
Mahdi Rouhbakhsh N., Seyed Arash Ghoreishi
We investigate minimum-error (ME) discrimination for mixed qubit states using a geometric approach. By analyzing positive operator-valued measure (POVM) solutions and introducing L…
Minimum-error discrimination of thermal states
Seyed Arash Ghoreishi, Mario Ziman
We study several variations of the question of minimum-error discrimination of thermal states. Besides of providing the optimal values for the probability of error, we also charact…
Classicality of the heat produced by quantum measurements
M. Hamed Mohammady
Quantum measurement is ultimately a physical process, resulting from an interaction between the measured system and a measuring apparatus. Considering the physical process of measu…
A model for optimizing quantum key distribution with continuous-wave pumped entangled-photon sources
Sebastian Philipp Neumann, Thomas Scheidl, Mirela Selimovic +4
Quantum Key Distribution (QKD) allows unconditionally secure communication based on the laws of quantum mechanics rather then assumptions about computational hardness. Optimizing t…
Device-independent bounds from Cabello's nonlocality argument
Ashutosh Rai, Matej Pivoluska, Martin Plesch +3
Hardy-type arguments manifest Bell nonlocality in one of the simplest possible ways. Except for demonstrating nonclassical signature of entangled states in question, they can also…
Tripartite quantum-memory-assisted entropic uncertainty relations for multiple measurements
Hazhir Dolatkhah, Saeed Haddadi, Soroush Haseli +2
Quantum uncertainty relations are typically analyzed for a pair of incompatible observables, however, the concept per se naturally extends to situations of more than two observable…
Bloch sphere analog of qudits using Heisenberg-Weyl Operators
Gautam Sharma, Sibasish Ghosh, Sk Sazim
We study an analogous Bloch sphere representation of higher-level quantum systems using the Heisenberg-Weyl operator basis. We introduce a parametrization method that will allow us…
