Quantum Computing: A security threat?

As our world becomes increasingly digitized, quantum computers pose a significant threat to the security of our information. While classical computers use bits that are either 1 or 0, quantum computers use qubits that can be both 1 and 0 simultaneously. This allows them to perform calculations much faster than classical computers and opens up the possibility of factorizing large numbers very quickly using algorithms such as Shor's algorithm.

This poses a threat to security because quantum computers can easily break many of the cryptography schemes that are currently used to protect information. For example, RSA encryption, which is used to protect a variety of data including credit card information and government secrets, can be easily broken by a quantum computer.

To combat this threat, many researchers are working on developing quantum-resistant cryptography. This is a difficult task because the quantum computers of today are not yet powerful enough to break all of the proposed quantum-resistant cryptography schemes. As quantum computers become more powerful, it will be important to keep developing new quantum-resistant cryptography schemes to stay ahead of the curve.

One of the ways we are working to counter this threat is through the development of optical/quantum security keys. These keys function in a similar way as a traditional key and lock, however we use the special properties of superposition to provide an inconceivably large number of possible combinations that is secure from even quantum computers. These keys are going to be an important part of securing our digital future and will be able to be used in everything from physical to digital locks, as a one-way hashing device, a quantum TPM, and much more!

It will likely take a few years before these keys become commercially available. In the meantime, there are some things that can be done to protect information from quantum computers. One is to use quantum key distribution, which allows two parties to share a key in a way that is secure against quantum computers. Additionally, it is important to keep information safe by using multiple layers of security, so that if one layer is broken, the others will still provide protection. As quantum computers become more powerful, they will pose an increasingly serious threat to the security of our information. However, by using quantum-resistant cryptography, our Q-Key technology, and other security measures, we can protect our data from these quantum threats and restore the trust we lost due to quantum optimizations.
