Abstract

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.

Metamaterial absorber for dual-rail photonic qubit filtering

Anton N. Vetlugin, Salih Yanikgonul, Rongrong Guo +4 more

We demonstrate manipulation of a photonic qubit, encoded in a dual-rail basis, by a plasmonic metamaterial absorber. The metamaterial is designed in a way to transmit a single photon, occupying anti-symmetric superposition of two spatial modes, without losses and to absorb its symmetric superposition completely. Thus, whatever the input state of the dual-rail photon, it can leave the absorber in anti-symmetric state only. Probability to pass through the absorber is defined by the amplitude of the anti-symmetric part in the input photon state. To verify this phenomenon, we assembled actively stabilized in-fibre quantum network containing fully-fiberized metamaterial package. By altering the input state of the photon propagating in the network and passing through metamaterial, we measure the output state of the photon and show that it is coherent and does not depend on the input state of the photon. By varying the input state, we also affect the probability of the photon to pass through the absorber. All the results are in a good agreement with the above discussion. We notice, that absorber can be designed in an opposite way: to transmit symmetric state and to absorb anti-symmetric one. Proposed devices can be employed in quantum computation schemes with dual-rail encoding as well as in other protocols of quantum information, operating with single photons or weak coherent states.

Distillation of photon entanglement using a plasmonic metamaterial

Motoki Asano, Muriel Bechu, Mark Tame +7 more

Plasmonics is a rapidly emerging platform for quantum state engineering with the potential for building ultra-compact and hybrid optoelectronic devices. Recent experiments have shown that despite the presence of decoherence and loss, photon statistics and entanglement can be preserved in single plasmonic systems. This preserving ability should carry over to plasmonic metamaterials, whose properties are the result of many individual plasmonic systems acting collectively, and can be used to engineer optical states of light. Here, we report an experimental demonstration of quantum state filtering, also known as entanglement distillation, using a metamaterial. We show that the metamaterial can be used to distill highly entangled states from less entangled states. As the metamaterial can be integrated with other optical components this work opens up the intriguing possibility of incorporating plasmonic metamaterials in on-chip quantum state engineering tasks.

Metamaterial Coherent Plasmonic Absorption With a Single Photon

With a plasmonic metamaterial absorber of sub-wavelength thickness we demonstrated that coherent absorption can be observed even with a single photon that could be coupled with nearly 100% probability into a localized plasmon.
