Device independent state estimation based on Bell's inequalities (2009)
Liew, T. C. H., Massar, S., McKague, M., Scarani, V.
The only information available about an alleged source of entangled quantum states is the amount $S$ by which the Clauser-Horne-Shimony-Holt (CHSH) inequality is violated: nothing is known about the...
A new physical principle: Information Causality (2009)
Pawlowski, M., Paterek, T., Kaszlikowski, D., Scarani, V., Winter, A., Zukowski, M.
Quantum physics exhibits many remarkable features. For example, it gives probabilistic predictions (non-determinism), does not allow copying of unknown states (no-cloning), its correlations are...
Pseudo-telepathy: input cardinality and Bell-type inequalities (2006)
Gisin, N., Methot, A. A., Scarani, V.
Pseudo-telepathy is the most recent form of rejection of locality. Many of its properties have already been discovered: for instance, the minimal entanglement, as well as the minimal cardinality of...
Fidelity of an optical memory based on stimulated photon echoes (2006)
Staudt, M. U., Hastings-Simon, S. R., Nilsson, M., Afzelius, M., Scarani, V., Ricken, R., ...
We investigated the preservation of information encoded into the relative phase and amplitudes of optical pulses during storage and retrieval in an optical memory based on stimulated photon echo. By...
An anomaly of non-locality (2006)
Ever since the work of Bell, it has been known that entangled quantum states can rise non-local correlations. However, for almost forty years, it has been assumed that the most non-local states would...
Violation of Bell's inequalities implies distillability for N qubits (2001)
Acin, A., Scarani, V., Wolf, M. M.
We consider quantum systems composed of $N$ qubits, and the family of all Bell's correlation inequalities for two two-valued measurements per site. We show that if a $N$-qubit state $\rho$ violates...
Ziman, M., Stelmachovic, P., Buzek, V., Hillery, M., Scarani, V., Gisin, N.
We design a universal quantum homogenizer, which is a quantum machine that takes as an input a system qubit initially in the state $\rho$ and a set of N reservoir qubits initially prepared in the...
Gisin, N., Scarani, V., Tittel, W., Zbinden, H.
Past, present and future experimental tests of quantum nonlocality are discussed. Consequences of assuming that the state-vector collapse is a real physical phenomenon in space-time are developed....
Faist, A., Bauen, A., Eckerström, P., Scarani, V.
Sous le nom de "Denkraum", l'architecte R. Miloni, associé à des industriels du secteur du bâtiment, a proposé un nouveau concept de bureau. Ce concept vise un confort thermique élevé, un...
