Efficient Energy-Constrained Semi-Device-Independent QRNG with an Integrated Heterodyne Receiver
Mattia Sabatini, Carles Roch i Carceller, Tommaso Bertapelle +10
Semi-device-independent QRNG frameworks represent a particularly attractive approach, combining strong security guarantees with high randomness generation rates while relying only…
Faking entanglement with imperceptible measurement deviations
Jaime Moreno, Elna Svegborn, Simon Morelli +4
Quantum entanglement is a central resource underpinning emerging quantum technologies, enabling capabilities beyond those of classical systems. Accurate verification of entanglemen…
Entanglement in prepare-and-measure scenarios without receiver inputs
Elna Svegborn, Armin Tavakoli
The most elementary prepare-and-measure scenarios have no independent measurement inputs. No inputs mean that quantum advantages require two indispensable ingredients: shared entan…
Resource theory of interactive quantum instruments
Chung-Yun Hsieh, Armin Tavakoli, Huan-Yu Ku +1
Quantum instruments describe both the classical outcome and the updated quantum state in a measurement process. To do this in a non-trivial way, instruments must have the capabilit…
Semidefinite block-matrix relaxations for computing quantum correlations
Nicola D'Alessandro, Carles Roch i Carceller, Armin Tavakoli
Bounding the correlations predicted by quantum theory is an important challenge in quantum information science. Today's leading approach is semidefinite programming relaxations, bu…
The role of entanglement in energy-restricted communication and randomness generation
Carles Roch I Carceller, Armin Tavakoli
A promising platform for semi-device-independent quantum information is prepare-and-measure experiments restricted only by a bound on the energy of the communication. Here, we inve…
Unlimited quantum correlation advantage from bound entanglement
Armin Tavakoli, Carles Roch i Carceller, Lucas Tendick +1
Entangled states that cannot be distilled to maximal entanglement are called bound entangled and they are often viewed as too weak to break the limitations of classical models. Her…
Bound entangled states are useful in prepare-and-measure scenarios
Carles Roch I Carceller, Armin Tavakoli
We show that bipartite bound entangled states make possible violations of correlation inequalities in the prepare-and-measure scenario. These inequalities are satisfied by all clas…
Semidefinite relaxations for high-dimensional entanglement in the steering scenario
Nicola D'Alessandro, Carles Roch i Carceller, Armin Tavakoli
We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method…
Imprecision plateaus in quantum steering
Elna Svegborn, Nicola d'Alessandro, Otfried Gühne +1
We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when in…
