Ultrafine Entanglement Witnessing
Farid Shahandeh, Martin Ringbauer, Juan C. Loredo +1
Entanglement witnesses are invaluable for efficient quantum entanglement certification without the need for expensive quantum state tomography. Yet, standard entanglement witnessin…
Experimental Simulation of Closed Timelike Curves
Martin Ringbauer, Matthew A. Broome, Casey R. Myers +2
Closed timelike curves are among the most controversial features of modern physics. As legitimate solutions to Einstein's field equations, they allow for time travel, which instinc…
Characterizing quantum dynamics with initial system-environment correlations
Martin Ringbauer, Christopher J. Wood, Kavan Modi +3
We fully characterize the reduced dynamics of an open quantum system initially correlated with its environment. Using a photonic qubit coupled to a simulated environment we tomogra…
Information Causality in the Quantum and Post-Quantum Regime
Martin Ringbauer, Alessandro Fedrizzi, Dominic W. Berry +1
Quantum correlations can be stronger than anything achieved by classical systems, yet they are not reaching the limit imposed by relativity. The principle of information causality…
