Welcome back, my cyberwarriors!
As you know, quantum computers represent a new technology of computing that many believe is the next wave in information technology. It promises the ability to do calculations at speeds unfathomable right now, even for our most powerful supercomputers!
Without going too deeply into the physics and technology, these are the machines that take advantage of what we now know about quantum physics. Quantum computers are advanced computing machines that use these principles from quantum physics to solve complex problems that are too complex for our traditional computers.
As you know, our preferred asymmetric encryption algorithms, RSA and ECC, rely upon the difficulty and time it requires to solve these algorithms. In other words, the confidentiality of our data is dependent how long and compute intensive these algorithms are to solve. With quantum computers, that difficulty is reduced by many orders of magnitude. For instance, cracking RSA-2048 with traditional computers might take billions of years, while with a quantum computer this time can be reduced to minutes.
Why Are They Faster?
Unlike classical bits that are 0 or 1, quantum bits (qubits) use superposition to exist as both 0 and 1 simultaneously, allowing them to process vast amounts of potential solutions at once. They also use entanglement to interlink, enhancing the complexity and efficiency of their computations. Shor’s algorithm uses these properties to quickly break this type of encryption.
When Will This Threat be Real?
Back in August 2025, on David Bombal’s YouTube channel, I predicted that quantum computers would break asymmetric encryption in 3 years. Many people, including some cryptography experts, laughed and scoffed (read the comments).

Recently, March 2025, Google researchers changed their prediction that quantum computers would be able to break this cryptography from 2030+ to 2029, precisely 3 years. Google is now urges our industry to adopt quantum-resistant (PQC) cryptography immediately!
On April 14, NVIDIA, the leading chip developer for artificial intelligence systems, announced their Quantum Day where they described how they are building tomorrow’s quantum computers. Can you risk ignoring NVIDIA?
What is Post-Quantum Cryptography?
Post Quantum Cryptography are algorithms designed to be resistant to quantum attacks. These algorithms replace our current methods (RSA/ECC) with new algorithms such as lattice-based cryptography. The National Institute of Standards and Technology (NIST) in the US has new standards for these techniques but this is a moving target as quantum computers and new algorithms are developed.
Some of the drawbacks of PQC at the moment are larger key sizes and, hence, slower handshakes that if left un-revised, will increase latency in our networks and may require new network infrastructure.
Prepare Your Network and Data!
To prepare for this eventuality, Hackers-Arise is now offering a new training:
Preparing Your Network for a Post-Quantum World, August 25-27
This will be a 3-day training to help you and your organization prepare and keep your data confidential in a post quantum world.
It is part of our elite Subscriber Pro program
