David Firnhaber holds a PhD in Technology Innovation Management for his publication in the field of Post-Quantum Cryptography (PQC) regarding the future of quantum decryption. He is currently a professor at Ivy Tech Community College and is pursuing a second PhD in Cybersecurity GRC while focusing his research on human trafficking in cyberspace.
As we navigate further into the quantum age, the convergence of cryptography and quantum computing is reshaping our digital landscape. In my previous article, The Quantum Shift in Cybersecurity and Why Businesses Must Prepare Now, we explored the emerging challenges posed by quantum computing. Now, let's delve into the latest advancements and why it’s crucial to adopt Post-Quantum Cryptography (PQC) solutions today.
PsiQuantum's bold vision and the milestone of 1 million logical qubits
In the quest for quantum supremacy, PsiQuantum is spearheading a monumental project in Brisbane, Australia, to develop a 1 million qubit quantum computer by 2027. This ambitious initiative, backed by nearly $1 billion in government investment, underscores the significance of quantum computing for the future of technology.

The urgency of post-quantum cryptography (PQC)
The rapid advancement of quantum computing technologies, exemplified by PsiQuantum's efforts, highlights the urgency for organizations to transition to PQC. My research, as detailed in The Looming Threat of Post-Quantum Cryptography, indicates that a quantum computer with 1 million logical qubits could decrypt RSA-2048 encryption, a standard widely used today. This presents a clear and present danger to the secure communications we rely on.
