Abstract

We propose the teleportation between 795nm (Rubidium D1 line) and 1608nm (telecom L-band) for applications in quantum networks using an OPO above the threshold. In the preliminary results, we demonstrate an unconditional quantum teleportation with a fidelity of 56.2(5)% at a slightly shifted frequency.

Teletransporte quântico incondicional de estados de variáveis contínuas de cores distintas: do infravermelho próximo às bandas de telecomunicações

Felipe Lucas Gewers

Quantum teleportation is the basis for numerous quantum applications, with the continuous-variable (CV) protocol having the significant advantage of being unconditional and deterministic, allowing every input state to be teleported. In the context of quantum networks, quantum channels connecting different wavelengths can be used in quantum hybrid technologies, linking different quantum platforms with distinct purposes that interact with light at specific wavelengths. Our approach to building these continuous-variable quantum channels is through quantum teleportation between quadratures of fields at widely different frequencies. To achieve this, we employ a triply resonant optical parametric oscillator (TROPO) operating above threshold as a source of two-mode entangled states. Pumped by a 532 nm Nd:YAG second harmonic laser, the system generates intense beams at 794.4(4) nm (377 THz; near-infrared compatible with the rubidium D1 line) and 1611(3) nm (186 THz; telecommunication L-band), with a frequency separation of 191 THz, which is over one octave. Using the resonator-assisted auto-homodyne technique, we implement the teleportation protocol to transfer a displaced coherent state from the infrared to the telecommunication band. In this work, we report the first demonstration of multi-color continuous-variable (CV) quantum teleportation bridging distinct frequency bands. This also marks the first implementation of teleportation between the sideband modes of intense beams that surpasses the classical fidelity limit. Additionally, we provide the first full characterization of the individual sideband modes in widely separated signal and idler fields generated by an above-threshold optical parametric oscillator. This demonstration paves the way for the development of hybrid quantum systems with enhanced connectivity.

Wavelength conversion for single-photon polarization qubits through continuous-variable quantum teleportation

Xi-Wang Luo, Chuanwei Zhang, Irina V. Novikova +2 more

A quantum internet connects remote quantum processors that need to interact and exchange quantum signals over a long distance through photonic channels. However, these quantum nodes operate at the wavelength ranges unsuitable for long-distance transmission. Therefore, quantum wavelength conversion to telecom bands is crucial for long-distance quantum networks based on optical fiber. Here, we propose wavelength conversion devices for single-photon polarization qubits using continuous-variable quantum teleportation that can efficiently convert qubits between near-infrared (780--795 nm suitable for interacting with atomic quantum nodes) and telecom wavelength (1300--1500 nm suitable for long-distance transmission). The teleportation uses entangled photon fields (i.e., nondegenerate two-mode squeezed state) that can be generated by four-wave mixing in a rubidium atomic gas using a diamond configuration of atomic transitions. The entangled fields can be emitted in two orthogonal polarizations with locked relative phase, making them especially suitable for interfacing with single-photon polarization qubits. Our work may pave the way for the realization of long-distance quantum networks.

Telecom-wavelength quantum teleportation using frequency-converted photons from remote quantum dots

Tim Strobel, Michal Vyvlečka, Ilenia Neureuther +13 more

A global quantum internet is based on scalable networks, which require reliable quantum hardware. Among them are quantum light sources providing deterministic, high-brightness, high-fidelity entangled photons and quantum memories with coherence times exceeding the millisecond range. Long-distance operation demands quantum light sources emitting at telecommunication wavelengths. A cornerstone for such networks is the demonstration of quantum teleportation. Here, we realize full-photonic quantum teleportation employing semiconductor quantum dots, which can fulfill all the aforementioned requirements. Two remote GaAs quantum dots, emitting in the near-infrared, are used: one as an entangled-photon pair source and the other as a single-photon source. During the experiment, the single photon is prepared in conjugate polarization states and interfaced with the biexciton emission of the entangled pair employing a polarization-selective Bell state measurement. This process teleports the respective polarization state onto the exciton emission of the entangled pair. The frequency mismatch between the triggered sources is erased using two polarization-preserving quantum frequency converters, enabling remote two-photon interference at telecommunication wavelengths, yielding a visibility of 30(1)%. A post-selected teleportation fidelity up to 0.721(33), significantly above the classical limit, demonstrates successful quantum teleportation between light from distinct sources. These results mark an important development for semiconductor-based quantum light sources.

High Fidelity Quantum Teleportation

Hidehiro Yonezawa

Quantum teleportation is one of the most fundamental subjects in quantum information technology. This is because quantum teleportation can be used as not only a communication network but also a building block for universal quantum information processing. It is well known that there are two approaches (i. e. discrete and continuous variable approaches) in quantum information processing. In particular, continuous variable one has some advantages, that is, capability for deterministic and efficient quantum operations. In the case of continuous variable quantum teleportation, however, we cannot teleport quantum states perfectly due to finite level of quadrature squeezed states. Hence it is important to improve the fidelity of teleportation to realize more advanced quantum network and circuits. Thanks to the recent improvement of squeezing level, fidelity up to F=0.83 has been achieved. In this article, we review the experiment of high fidelity quantum teleportation for continuous variables, and its applications.
