Is BSI approval the ultimate security guarantee?

In the face of new and ever-evolving threats to data in transport, enterprises, governmental organizations and financial institutions are having to deploy robust security solutions. They need encryption technology that can protect data in-flight without increasing latency and hampering throughput. Thankfully, there’s a way for operators to be sure they are using the most reliable encryption technology to safeguard sensitive data, and that's to select solutions with accreditation from key cybersecurity bodies …

From the article:

So-called quantum key distribution is unconditionally secure--it offers perfect secrecy guaranteed by the laws of physics.

Or at least that's what everyone thought. More recently, various groups have begun to focus on a fly in the ointment: the practical implementation of this process. While quantum key distribution offers perfect security in practice, the devices used to send quantum messages are inevitably imperfect.

It will be interesting to see how quantum computing practically differs from the theoretics of quantum physics; I suspect that efforts will be made to find 'kludges' that will ultimately be the source of practical problems to quantum-based security and computing efficiency. Of course, this is a similar issue that currently besets security and computing: dealing with real-world materials and accommodating imperfections (and variable modes of breaking security models that extend beyond the system being imagined) are amongst the most pressing of today's issues.
