The speed of quantum information and the preferred frame: analysis of experimental data

Valerio Scarani, Wolfgang Tittel, Hugo Zbinden +1 more

The results of EPR experiments performed in Geneva are analyzed in the frame of the cosmic microwave background radiation, generally considered as a good candidate for playing the role of preferred frame. We set a lower bound for the speed of quantum information in this frame at 1.5 x 10^4 c

Experimental Test of Relativistic Quantum State Collapse with Moving Reference Frames

Hugo Zbinden, Jurgen Brendel, Wolfgang Tittel +1 more

An experimental test of relativistic wave-packet collapse is presented. Thetested model assumes that the collapse takes place in the reference framedetermined by the massive measuring detectors. Entangled photons are measuredat 10 km distance within a time interval of less than 5 ps. The two apparatusesare in relative motion so that both detectors, each in its own inertialreference frame, are first to perform the measurement. The data alwaysreproduces the quantum correlations and thus rule out a class of collapsemodels. This also sets a lower bound on the ''speed of quantum information'' to$10^{7}$ times the speed of light.

An experimental test of relativistic wave-packet collapse is presented. The tested model assumes that the collapse takes place in the reference frame determined by the massive measuring detectors. Entangled photons are measured at 10 km distance within a time interval of less than 5 ps. The two apparatuses are in relative motion so that both detectors, each in its own inertial reference frame, are first to perform the measurement. The data always reproduces the quantum correlations and thus rule out a class of collapse models. The results also set a lower bound on the `speed of quantum information' to 2/3 ×10 7 and 3/2 ×10 4 times the speed of light in the Geneva and the background radiation reference frames, respectively. The very difficult and deep question of where the collapse takes place—if it takes place at all—is considered in a concrete experimental context.
