Abstract

We experimentally demonstrate for the first time that absorption of one of the photons from the entangled pair can be switched on and off by controlling the Pancharatnam-Berry phase of the other photon.

Non-Local Control of Light Dissipation with Pancharatnam-Berry Phase

Ruixiang Guo, Anton N. Vetlugin, Cesare Soci +1 more

Pancharatnam-Berry (PB) phase is acquired by the light during a cyclic evolution on the Poincare sphere. The PB phase plays a crucial role in light interference phenomena and was exploited to demonstrate wavefront shaping, light deflection and focusing lens applications [1] . Here, we experimentally demonstrate for the first time that by applying PB phase to one of the photons from the entangled pair, the dissipation experienced by the second remotely located photon can be switched on and off.

Pancharatnam–Berry geometric phase memory based on spontaneous parametric down-conversion

Wen-Rong Qi, Rui Liu, Ling‐Jun Kong +5 more

Phase memory is an effect in which the interaction between a coherent pump beam and a nonlinear crystal generates photon pairs via the spontaneous parametric down-conversion process, then the down-converted photons (signal and idler) can carry the phase information of the pump beam. There has been much research on the memory of the dynamic phase so far; however, there is no report on the memory of non-dynamic phase, to the best of our knowledge. Here we acquire a Pancharatnam-Berry (PB) geometric phase in a physical system when light travels along a trajectory in polarization-state space. Induced coherence occurs in a cascaded scheme composed of two nonlinear crystals, when the idler photons in both crystals are aligned to be indistinguishable. A NOON ($N\; = \;{2}$N=2) state is established when blocking the two idler photons. We explore the PB geometric phase memory of the NOON state and induced coherence. We find that the first-order interference of the two-photon state or signal photons can be controlled by introducing the PB geometric phase to the pump light. This may facilitate precise control of the phase of the down-converted photons.

Nonlocal Modulation of Biphotons

Steven Sensarn, G. Y. Yin, Stephen E. Harris

We experimentally describe a new quantum effect where temporal modulation of one photon of an entangled pair, as measured by frequency-domain correlation, may be negated or enhanced by modulation of the second photon.

“Remote Control” of coherent light absorption with entangled photons

Charles Altuzarra, Stefano Vezzoli, João Valente +4 more

Using a source of entangled photons we show that polarization-sensitive detection of the photons can be used to switch “on” and “off” absorption of the other photon in a thin plasmonic metamaterial film.
