Hacking energy-time entanglement-based systems with classical light
Jonathan Jogenfors, Ashraf M. Elhassan, Johan Ahrens +2
Photonic systems based on energy-time entanglement have been proposed to test local realism using the Bell inequality. A violation of this inequality normally also certifies securi…
Experimental observation of Hardy-like quantum contextuality
Breno Marques, Johan Ahrens, Mohamed Nawareg +2
Contextuality is a fundamental property of quantum theory and a critical resource for quantum computation. Here, we experimentally observe the arguably cleanest form of contextuali…
Quantum bidding in Bridge
S. Muhammad, A. Tavakoli, M. Kurant +3
Quantum methods allow to reduce communication complexity of some computational tasks, with several separated partners, beyond classical constraints. Nevertheless, experimental demo…
