In the last years, the mid-infrared (MIR) spectral region (2--25 $\mu$m) has emerged as a domain of great interest in many areas of science and technology. Quantum optics applications are also considering moving to MIR since the longer wavelength is appealing for the ease of photon manipulation. However, for quantum optics, single-photon measurements are essential and with the present MIR detectors, they were thought to be impossible in the MIR. Here we show that by spectral translation, it is possible to develop a room temperature mid-infrared detector suitable for coincidence measurements on non-degenerate twin photons.
