InfiniQuant is a team hosted within the Quantum Information Processing group of Christoph Marquardt at the Max Planck Institute for the Science of Light in Erlangen, Germany. Led by scientists Imran Khan and Christoph Marquardt, the team focuses on investigating possible applications for quantum communication scenarios. Quantum communication, which utilizes the resources of quantum mechanics, is the transfer of information.

The most prominent protocol used in this field is quantum key distribution (QKD), which allows for the exchange of secret keys in a provably secure manner based on the laws of physics. Unlike classical cryptography, QKD remains secure even against future attacks by more powerful classical or quantum computers. InfiniQuant's technology is based on coherent telecommunication technology, which is compatible with existing telecom infrastructure.

Although QKD currently requires dedicated hardware, its implementation cost is steadily decreasing through ongoing research and development. The high level of security provided by QKD, in conjunction with classical cryptography, makes it particularly suitable for long-term security applications. In summary, InfiniQuant is a brand at the forefront of quantum communication, offering secure telecommunications solutions based on provably secure key distribution protocols and classical cryptography
