QSIMPLUS is a company that specializes in Quantum Computing technologies. Know for its QSIMpro quantum communications software simulator released last year. The company comes back to CES with another innovation in the form of QSIMpro-LAN, a software that allows operating local area Quantum networks.Quantum computers and networks are very sensitive to their environment. One primary challenge is quantum decoherence, where quantum states can be easily disrupted, especially if the quantum information traverses various mediums that may trigger decoherence.
In their press release, QSIMPLUS doesn’t dive deep into the technical details, but QSIMpro-LAN extends the reach of a quantum network by introducing mobile nodes that allow ordinary computers to communicate with a quantum network.
The software takes care of the Quantum Key Distribution as your typical computer typically lacks the ability to generate and process quantum keys for secure communications. As far as I know, this is still the topic of intense research, so having a functional way to do this sounds impressive.
To a non-technical person, this looks very much like network address translation (NAT) for quantum networks and the QSIMpro-LAN acts like a quantum router.
Quantum networks have many advantages, including some related to security. For example, it is in theory impossible to eavesdrop such a network since quantum theory stipulates that it is impossible to make a copy quantum state without being detected.
Having more computers and people access a highly secure network can be extremely beneficial for productivity and security. According to QSIMPLUS, “the main customers are organizations that require robust data security (such as defense, banking and data centers)”.
