The quantum threat is a serious one, and businesses and governments need to act now to secure themselves against it.
The reasonable worst case for Q-day is 2027, earlier than many assume.
Fortunately, new quantum-resistant math-based cryptography is on its way to meet this threat.
This is being joined by a wealth of other new techniques setting out to meet diverse user needs.
However, to fully appreciate the emerging competitive dynamics and government actions in this sector, we also have to understand the longer-term revolution that is underway in wider quantum networking technology.
Some believe that one day this will lead to the creation of an entanglement based Quantum Internet.
The migration to post-quantum cryptography is a complex and challenging process, but it is essential that it is completed as soon as possible.
There are a number of different approaches to quantum-safe cryptography, and the best approach for a particular organization will depend on its specific needs.
It is important to start planning for the quantum transition now, so that organizations are not caught off guard when the threat becomes reality.
 
Here are some of the key challenges that organizations will face in the transition to quantum-safe cryptography:
The need to update existing protocols and standards to use quantum-safe algorithms.
The need to ensure that new implementations of quantum-safe algorithms are secure.
The need to educate users about the quantum threat and the importance of using quantum-safe cryptography.
 
Despite the challenges, the transition to quantum-safe cryptography is essential to ensure the security of our digital infrastructure in the future. Organizations that start planning now will be well-positioned to meet this challenge.
