Insider Brief

  • Chief Information Security Officers (CISOs) and tech teams will be staff members most affected by quantum computers.
  • These experts are often looked at in shaping responses to threats and opportunities posed by new technologies.
  • There are several steps CISOs and tech team members can take to be responsible quantum advocates in the business or organization.

The era of quantum computing appears to be drawing closer, and it brings with it a wave of transformative potential, not just for industries directly involved in quantum technologies, but for virtually every sector and industry where quantum use cases may one day arise. Chief Information Security Officers (CISOs) and technical teams, therefore, must grasp the fundamentals of this emerging technology. 

This article is meant to demystify quantum computing, set expectations, highlight potential impacts and cover challenges and strategic considerations for CISOs and technical teams.

Crucially, the effects of quantum computing are expected to ripple across industries. This article, then, is also aimed at technical teams in businesses and organizations not primarily associated with quantum computing. In fact, these may be the most vulnerable to quantum’s negative impacts, as well as ideally positioned to seize its many competitive advantages.

Rise of The Quantum CISO? A Guide to Prepare CISOs and Technical Teams For The Quantum Era

Understanding Quantum Computing

Quantum computing operates on the principles of quantum mechanics, the science of the very small. While the principles of quantum mechanics may sound somewhat strange, quantum theory and experimental evidence have a century of vetting.

Unlike classical computers, which use bits (0s or 1s), quantum computers use quantum bits, or qubits, that can exist in multiple states simultaneously, also called superposition. 

Quantum entanglement is a physical phenomenon where pairs or groups of particles interact in such a way that the quantum state of each particle cannot be described independently of the state of the others, even when the particles are separated by a large distance

Superposition, along with entanglement, are two reasons that quantum computers have unique computational power and give them the potential for solving very difficult problems quickly and efficiently.

Like any superpower, there are also super problems. Quantum computing’s operational kryptonite is its vulnerability to errors. If superposition and entanglement sound like sensitive states, that’s because they are and that makes them vulnerable to a range of environmental noises that can throw off calculations.

Error correction – which is making dramatic progress – is still a costly need of quantum computing approaches.

Currently, though, in the NISQ – noisy intermediate-scale quantum – era, quantum computers have not overcome the challenges of error correction to better their classical computer and supercomputer counterparts at many computational tasks.

Potential Impacts of Quantum Computers for CISOs And Tech Teams

However, once quantum computers are robust and stable enough, they offer disruptive power – and by disruptive, we mean in both the positive and negative sense. Here are a few potential impacts that could affect the duties of a CISO.

Enhanced Computational Capabilities: Quantum computers can solve complex problems much faster than classical computers. This ability is particularly relevant in fields like cryptography, material science, and pharmaceuticals.

Cryptography and Cybersecurity: Quantum computing poses a significant threat to current cryptographic standards. RSA and ECC, the bedrock of digital security, could potentially be broken by quantum algorithms, like Shor’s algorithm. Quantum networking, on the other hand, could one day offer hard-to-hack communications.

Data Analysis and AI: There still remains a lot of debate on this one, but, theoretically, with their immense processing power, quantum computers can vastly improve data analytics and machine learning, leading to more advanced AI applications.

Facing Quantum’s Technical Challenges

Let’s game plan for the scenario that quantum computers do reach fault-tolerant status – or, a time when quantum computers can work correctly even if they experience errors or disturbances. What should CISOs be ready for, how should they prepare and what preliminary steps should they take? Here are a few: 

Quantum-Resistant Cryptography Education: As CISOs, it is crucial to stay ahead of the curve by adopting quantum-resistant cryptographic techniques. This transition involves researching and implementing post-quantum cryptography (PQC) algorithms.

Investment in Quantum Skills: Organizations should invest in training and resources to foster quantum literacy. Understanding quantum algorithms and their implications is vital for making informed decisions.

Data Privacy: With quantum computing, the threat to data privacy intensifies. Organizations must reassess their data protection strategies to safeguard against future quantum attacks.

Partnerships and Collaborations: Engaging with quantum computing firms and academic institutions can provide valuable insights and keep your organization abreast of the latest developments.


As a CISO, you are often considered the organization’s thought leader in terms of safe technical evolution. Often you are looked on as a technological leader broadly. Tech team leaders are also critical voices in adopting and adapting to technological disruption.

Strategic Considerations for Quantum Era Tech Teams 

As we have tried to set expectations, we emphasize again that quantum computing is still in its nascent stages. However, its potential impact is too significant to ignore and CISOs should consider being prepared for that eventuality. As a CISO, you are often considered the organization’s thought leader in terms of safe technical evolution. Often you are looked on as a technological leader broadly. Tech team leaders are also critical voices in adopting and adapting to technological disruption.

Here are some key steps to prepare for quantum:

Long-term Planning: When you develop long-term organizational strategies, remember to include quantum computing in those considerations.

Risk Assessment: Assess the risks quantum computing poses to your organization, particularly in areas like data security and intellectual property.

Innovation and Adaptation: Embrace the potential for innovation that quantum computing brings. Encourage a culture of adaptation and readiness for technological shifts.

What if You’re Ready to be a Quantum CISO, But Your Organization Isn’t

There is another uncomfortable possibility. It could be that you find yourself as a member of a technical team that believes in the oncoming wave of quantum tech disruption, but your organization does not. In fact, it might be indifferent, if not antagonistic toward the possibilities or a quantum era. In this case, things get tricky.

But here are some options on the table:

Educate and Raise General Awareness: As mentioned before, the best place to start is by educating yourself and key stakeholders in your organization about quantum computing. This includes understanding the basics of quantum technology, its potential impact on cybersecurity (especially encryption), and the timeline for meaningful developments. You should also be aware of the counter-arguments for not being quantum ready: it’s expensive, it’s too far in the future, I’m afraid I’ll lose my job, etc. Awareness sessions, workshops, or inviting expert speakers can help disseminate this knowledge.

Educate and Engage Senior Leadership: Begin by educating the senior leadership team about the fundamentals and potential impacts of quantum computing. Tailor the information to highlight how quantum computing could affect the organization’s strategic objectives, competitive landscape and cybersecurity posture.

Focus on Outcomes: When you discuss quantum, use language and examples that resonate with business outcomes rather than technical jargon. 

Bring In Experts: Consider organizing executive briefings, bringing in external quantum computing experts, or attending relevant conferences together. It’s essential that the leadership understands the urgency and the need for investment in quantum readiness, as their support will be crucial for driving organization-wide initiatives and allocating necessary resources.

Assess Current Security Infrastructure: Evaluate your organization’s current cybersecurity infrastructure with a focus on areas that might be vulnerable to quantum attacks. This involves identifying and cataloging encryption methods in use, such as public key infrastructures, which might be vulnerable to quantum computing. Understanding where and how your organization uses encryption will be key to identifying risk areas.

Assess Quantum Skills and Partnership Possibilities: Encourage the development of quantum computing skills within your organization. This could involve training existing staff, hiring new talent with a background in quantum technologies, or forming partnerships with academic institutions or companies that specialize in quantum computing. Building a network with quantum experts can provide valuable insights and keep your organization updated with the latest developments.

Develop a Quantum-Resilient Strategy: Even if you don’t have organizational buy-in initially, work on developing a strategy that incorporates quantum-resistant algorithms and post-quantum cryptography. This might involve transitioning to quantum-safe encryption methods and updating existing security protocols. Keeping an eye on standards being developed by organizations like NIST (National Institute of Standards and Technology) in the field of post-quantum cryptography is crucial.

Be Prepared to Move On: This sounds heavy-handed and a little bit dramatic, but we include this as one option. If you believe quantum will become a wave of technological disruption and you are in an organization that is stodgily resisting preparation, the odds of this group successfully navigating the waves of impending change lower significantly. Also, facing the chaos of last minute adaption to quantum would not exactly be a period of work-life balance for you. In fact, it is likely to be a period of intense stress and very little reward.

Dealing With a Possible Quantum Paradigm Shift

Quantum computing is more than just a technological evolution; it’s a paradigm shift with the power to redefine how we approach computation and problem-solving. 

For CISOs and technical teams in industries not directly linked to quantum computing, the key is to stay informed, prepared and adaptable. 

Understanding quantum computing, its potential impacts, and strategic approaches is vital in navigating this new era. With thoughtful planning and investment in quantum-readiness, organizations can not only mitigate the risks but also seize the opportunities presented by this revolutionary technology.
