Quantum Internet hardware
The future of secure communication
One of the technical challenges in realizing quantum internet hardware is the detector. Highly specialized components, called superconducting nanowire single-photon detector (SNSPD), are used to detect single photons. One of the main roadblocks for the SNSPD cabling is detector density: the density of detector units on a given surface determines the chance of a photon landing on a detector. Scaling up the detector quantity is therefore critical in increasing detector sensitivity.
However, the scale-up of quantum internet hardware is not only limited by the detector chip. The control hardware also needs to scale-up proportionally. Below, in our case study highlights, you will see an example by one of our customers that has used multi-channel Cri/oFlex® to scale up their SNSPD system.
Cri/oFlex® cable for quantum internet
Quantum internet and quantum communication offer an intrinsically secure alternative to conventional cryptography. The trend in the field is to move towards faster entanglement rates, requiring a higher number of NV-centers and single-photon detectors. Supporting hardware challenges are often space constraints in cryostats and low cooling powers. Our Cri/oFlex® 2 and Cri/oFlex® 3 product lines enable microwave signal input and output for quantum communication experiments of the future, by offering microwave cabling that is:
