Abstract

Quantum nonlocality, i.e. the presence of strong correlations in spatially seperated systems which are forbidden by local realism, lies at the heart of quantum communications and quantum computing. Here, we use polarization-entangled photon pairs to demonstrate a nonlocal control of absorption of light in a plasmonic structure. Through the detection of one photon with a polarization-sensitive device, we can almost deterministically prevent or allow absorption of a second, remotely located photon. We demonstrate this with pairs of photons, one of which is absorbed by coupling into a plasmon of a thin metamaterial absorber in the path of a standing wave of an interferometer. Thus, energy dissipation of specific polarization states on a heat-sink is remotely controlled, promising opportunities for probabilistic quantum gating and controlling plasmon-photon conversion and entanglement.

“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.

We use single-photon interference on a metamaterial absorber to demonstrate quantum state filtering by dissipation, exploiting the metamaterial’s ability to distinguish between symmetric and anti-symmetric superpositions of a two-path wave function.

Coherent perfect absorption of single photons in a fiber network

Anton N. Vetlugin, Ruixiang Guo, Angelos Xomalis +4 more

Large distance implementation of quantum communication technologies requires coherent control of single photons in optical fiber networks. Here we demonstrate the phenomenon of coherent perfect absorption of single photons in a fully fiberized ultrathin plasmonic metamaterial fabricated at the end facet of an optical fiber. Continuous control of single-photon absorption probability is achieved by driving the network between the regimes of coherent total absorption and coherent total transmission. To circumvent phase fluctuations inherent to optical fiber networks, we implemented a reference-based postselection technique which yielded interference fringe visibility comparable to that of free space experiments. Coherent absorption of quantum light in fiber environment provides new opportunities for dissipative single-photon switching, filtering, and measurement, as well as for manipulation of entangled, weak coherent, and NOON states in optical fiber networks.

Quantum plasmonic N00N state in a silver nanowire and its use for quantum sensing

Yang Chen, Changhyoup Lee, Liu Lu +9 more

The control of quantum states of light at the nanoscale has become possible in recent years with the use of plasmonics. Here, many types of nanophotonic devices and applications have been suggested that take advantage of quantum optical effects, despite the inherent presence of loss. A key example is quantum plasmonic sensing, which provides sensitivity beyond the classical limit using entangled N00N states and their generalizations in a compact system operating below the diffraction limit. In this work, we experimentally demonstrate the excitation and propagation of a two-plasmon entangled N00N state (N=2) in a silver nanowire, and assess the performance of our system for carrying out quantum sensing. Polarization entangled photon pairs are converted into plasmons in the silver nanowire, which propagate over a distance of 5 um and re-convert back into photons. A full analysis of the plasmonic system finds that the high-quality entanglement is preserved throughout. We measure the characteristic super-resolution phase oscillations of the entangled state via coincidence measurements. We also identify various sources of loss in our setup and show how they can be mitigated, in principle, in order to reach super-sensitivity that goes beyond the classical sensing limit. Our results show that polarization entanglement can be preserved in a plasmonic nanowire and that sensing with a quantum advantage is possible with moderate loss present.

Remote preparation of single-plasmon states

Marie-Christine Dheur, Benjamin Vest, Éloïse Devaux +5 more

Quantum entanglement is a stunning consequence of the superposition principle. This universal property of quantum systems has been intensively explored with photons, atoms, ions, and electrons. Collective excitations such as surface plasmons exhibit quantum behaviors. We report the remote preparation of a single plasmon state through the projective measurement of a photon entangled with the plasmon. We achieved photon-plasmon entanglement by converting one photon of an entangled photon pair into a surface plasmon. The plasmon is tested on a plasmonic platform in a Mach-Zehnder interferometer. A projective measurement on the polarization of the photon allows the remote preparation of the interference state of the plasmon. Entanglement between particles of various nature paves the way to the design of hybrid systems in quantum information networks.

Transmission of entangled photons studied by quantum tomography: do we need plasmonic resonances?

Mathilde Remy, Bojana M. Bokić, Wakana Kubo +2 more

We performed quantum tomography to reveal the robustness of quantum correlations of photons entangled in polarisation after their interaction with plasmonic and nonplasmonic environments at normal incidence.The experimental findings clearly show that the visibility of quantum correlations survives the interaction, and that the presence of plasmonic resonances has not any significant influence on the survival of polarisation correlations for transmitted photon pairs.The results indicate that quantum states can be encoded into the multiple motions of a many-body electronic system without demolishing their quantum nature.The plasmonic structures and their resonances only enhance the overall transmission.Thus, they could benefit the pair detection rate, that is the number of coincidences per unit of time, but they do not affect the visibility of quantum correlations.We also performed quantum tomography of the entangled pairs after interaction with the continuous planar gold film as a function of the incidence angle.The latter illustrates the loss of polarization correlations that arises from the partially polarizing properties of the isotropic sample out of normal incidence.Our work shows that plasmonic structures are not needed to exploit quantum entanglement if the rate of coincidence counting is sufficient.
