An unconditional experimental test of Nonclassicality
A. Hameedi, B. Marques, P. Mironowicz +3
We theoretically introduce and experimentally demonstrate the realization of a nonclassicality test that allows for arbitrarily low detection efficiency without invoking any extra…
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:…
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…
Steering is an essential feature of non-locality in quantum theory
Ravishankar Ramanathan, Dardo Goyeneche, Sadiq Muhammad +4
A physical theory is called non-local when observers can produce instantaneous effects over distant systems. Non-local theories rely on two fundamental effects: local uncertainty r…
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…
