Abstract

We implement an entanglement distribution network based on wavelength-multiplexing and optical switching for quantum communication applications. Using a high-brightness source based on spontaneous parametric down-conversion in periodically-poled lithium niobate waveguides, we generate polarisation entangled photon pairs with a broad spectrum covering the telecom wavelengths around 1550 nm. The photon pairs have entanglement fidelities up to 99%, and are distributed via passive wavelength multiplexing in a static multi-user network. We furthermore demonstrate a possible network application in a scenario with a single centralised source dynamically allocating two-party entanglement to any pair of users by means of optical switches. The whole system, from the pump laser up to the receivers, is fibre and waveguide based, resulting in maximal stability, minimal losses and the advantage of readily integrable telecom components in the 1550 nm range.

Fig. 1

Outline of an entanglement distribution network. Each user is connected via a single quantum channel (solid lines) to the centralised entangled-photon-source (EPS). Entanglement (dotted arrows), used for quantum information tasks, can be shared between any two users on request (only certain combinations are shown).

Fig. 2
Fig. 2

Experimental setup with a cw-laser pumping two ppLN crystals in a Mach-Zehnder interferometer to create polarisation-entangled photon pairs. The pairs are split using a DWDM multiplexer, analysed using polarisation optics and detected with InGaAs single photon detectors. The active phase stabilisation of the interferometric part is achieved with the help of a fibre stretcher.

Fig. 3

Real part of the density matrices obtained from tomography measurements (raw coincidences) for each entangled channel pair. The elements of the imaginary parts are all smaller than 0.07.

Fig. 4
Fig. 4

Software-defined network (SDN) realisation with two optical switches for active, on-demand distribution of entanglement. Depending on the choice of the switch setting (I, II or III), different user pairs will share entangled photons for quantum information applications.

Table 1 Summary of results for the four entangled channel pairs, designated by their ITU numbers and central wavelengths. Coincidence rates and calculated fidelities and purities of the measured states are displayed. Fidelity and purity were calculated both for raw data and after background subtraction.

Table 2 Summary of results for the three switch settings in the SDN. Each setting results in two 2-party sharing of entangled states. Coincidence rates, calculated fidelities and purities (with and without background counts) for each user pair are listed.
