Increased Certification of Semi-device Independent Random Numbers using Many Inputs and More Postprocessing
Piotr Mironowicz, Armin Tavakoli, Alley Hameedi +3
Quantum communication with systems of dimension larger than two provides advantages in information processing tasks. Examples include higher rates of key distribution and random nu…
Spatial versus Sequential Correlations for Random Access Coding
Armin Tavakoli, Breno Marques, Marcin Pawlowski +1
Random access codes are important for a wide range of applications in quantum information. However, their implementation with quantum theory can be made in two very different ways:…
Bell-type Inequalities for Arbitrary Non-Cyclic Networks
Armin Tavakoli
Bell inequalities bound the strength of classical correlations between observers measuring on a shared physical system. However, studies of physical correlations can be considered…
Quantum Correlations in Connected Multipartite Bell Experiments
Armin Tavakoli
Quantum correlations arising in Bell experiments, involving a physical source that emits a quantum state to a number of observers, have been intensively studied over the last decad…
Quantum Communication Complexity using the Quantum Zeno Effect
Armin Tavakoli, Hammad Anwer, Alley Hameedi +1
The quantum Zeno effect (QZE) is the phenomenon where the unitary evolution of a quantum state is suppressed e.g. due to frequent measurements. Here, we investigate the use of the…
Maximal Non-Classicality in Multi-Setting Bell Inequalities
Armin Tavakoli, Stefan Zohren, Marcin Pawlowski
The discrepancy between maximally entangled states and maximally non-classical quantum correlations is well-known but still not well understood. We aim to investigate the relation…
The Magical Number Seven: An Unexpected Dimensional Threshold in Quantum Communication Complexity
Armin Tavakoli, Marcin Pawlowski, Marek Zukowski +1
Entanglement-assisted classical communication and transmission of a quantum system are the two quantum resources for information processing. Many information tasks can be performed…
Quantum Random Access Codes using Single -level Systems
Armin Tavakoli, Alley Hameedi, Breno Marques +1
Random access codes (RACs) are used by a party to despite limited communication access an arbitrary subset of information held by another party. Quantum resources are known to enab…
Quantum Clock Synchronization with a Single Qudit
Armin Tavakoli, Adán Cabello, Marek Żukowski +1
Clock synchronization for nonfaulty processes in multiprocess networks is indispensable for a variety of technologies. A reliable system must be able to resynchronize the nonfaulty…
Secret Sharing with a Single d-level Quantum System
Armin Tavakoli, Isabelle Herbauts, Marek Zukowski +1
We give an example of a wide class of problems for which quantum information protocols based on multi-system entanglement can be mapped into much simpler ones involving one system.…
