Tender Details

Quantum frequency converter At the DLR Institute of Quantum Technology, a C-band compatible quantum memory is being built as part of a quantum memory test stand (see schematic representation in Figure 1). The C-band photons of a photon pair source are on the Telekom wavelength of 1529.44nm and are routed via a fiber optic link to a Quantum Frequency Conversion System (QFC). This converts the photons to the Rb-87-D1 line at 794.98nm, so that they can then be stored in the quantum memory can be saved. A QFC system is therefore required that converts individual photons at 1529.44nm to 794.98nm using sum frequency generation (SFG). The system must take into account the quantum mechanical properties of the photons, in particular Coherence properties obtained. The system must contain the required pump laser. The connection to the structure takes place via PM fiber interfaces (FC/UPC) at the input and output. In addition, the system must have an additional optical output 1529.44nm, which is fed back into the photon pair source and into a locking system via a fiber optic. The photon pair source itself and the reference laser at 794.98nm (memory reference laser) are not part of this tender are provided by DLR. The system is intended to be operated in a 19" rack (rack cabinet provided by DLR) in a temperature-controlled laboratory and will only be used by qualified specialists.
