For many years, quantum computing lived mostly in the world of theory, research labs, and experimental projects. That is starting to change. Today, it is increasingly seen as one of the technologies with the greatest potential to reshape the way organizations solve complex problems.<\/p>\n
Its potential applications are broad. Artificial intelligence, logistics optimization, financial simulation, energy grid management, and drug discovery are just some of the areas where quantum computing could open new possibilities. This helps explain why public and private investment in the field continues to grow.<\/p>\n
Across Europe, North America, and the UK, funding for quantum research and infrastructure has been gaining momentum. At the same time, specialized companies continue to attract capital from international investors. The message is becoming clear: quantum computing is no longer just a scientific promise. It is becoming a strategic priority for competitiveness, technological sovereignty, and industrial innovation.<\/p>\n
But the same potential that makes quantum computing so relevant also raises a serious cybersecurity challenge.<\/p>\n
Many of the cryptographic systems that currently protect communications, financial transactions, digital identities, and critical infrastructure are based on mathematical problems that are extremely difficult for classical computers to solve. With sufficiently advanced quantum computers, some of those problems may no longer be difficult enough.<\/p>\n
In its study How Quantum Computing Will Upend Cybersecurity<\/a>, Boston Consulting Group estimates that, at the current pace of development, quantum computers with thousands of qubits could have more than a 50% probability of breaking algorithms currently in use, such as RSA-2048, by 2035<\/strong>.<\/p>\n <\/p>\n Single Sign-On (SSO) allows clinicians to use one credential<\/span><\/a> to access all of their clinical applications. Without it, the multiplication of passwords and fragmented logins creates a pressure triangle with consequences across three key dimensions:<\/span>\u00a0<\/span><\/p>\n The outcome is clear: higher support costs, risks that are harder to justify during audits, and IT teams trapped in reactive firefighting instead of proactive planning. For caregivers, it often feels like technology is slowing them down rather than helping them move faster.<\/span>\u00a0<\/span><\/p>\n As a recent <\/span>HealthTech Magazine<\/span><\/i> article (April 2025)<\/span><\/a> highlighted, SSO <\/span>\u201cbrings security and empathy together<\/span><\/b>\u201d by removing barriers that keep clinicians from focusing on what matters most: delivering the best possible care. That\u2019s exactly what <\/span>Imprivata OneSign<\/span><\/b> offers healthcare, transforming the concept of SSO into daily practice, tailored to both clinical and IT needs.<\/span><\/p>\n In this context, the transition to post-quantum cryptography should not be treated as a simple technical upgrade. It is a long-term transformation program, with implications for architecture, investment, risk, and business continuity. For CIOs, CISOs, and IT Managers, understanding how quantum computing and cybersecurity fit into the organization\u2019s roadmap<\/a> is becoming essential to making the right decisions before the threat becomes operational.<\/p>\n In this article, we look at three essential questions:<\/strong><\/p>\n The main impact of quantum computing on cybersecurity is related to asymmetric cryptography<\/strong>.<\/p>\n Algorithms such as RSA and ECC are widely used to protect digital communications, authenticate identities, and generate cryptographic keys, which are then used by symmetric algorithms such as AES. These mechanisms are part of the trust model behind many of the digital services and infrastructures that organizations rely on every day.<\/p>\n If quantum computers become powerful enough to break these algorithms, the impact will not be limited to one system or one application. It will affect an entire chain of trust, including:<\/p>\n When this chain of trust is weakened, the issue is no longer just technical. It becomes structural. An attacker may not be able to break a tunnel, key, or encrypted communication today. However, they may be able to record traffic, store encrypted material, and decrypt it later once quantum capabilities become available. This is known as a “harvest now, decrypt later”<\/strong><\/em> scenario<\/strong>.<\/p>\n The risk is particularly relevant in sectors where data retains strategic, legal, or reputational value for many years. Information that is protected today may still need to remain confidential in ten, fifteen, or twenty years.<\/p>\n That leads to a simple but difficult question: which information in your organization must remain confidential once quantum capabilities become accessible?<\/strong><\/p>\nWhy<\/span> SSO <\/span>is<\/span> Critical<\/span> in <\/span>Healthcare<\/span><\/span>\u00a0<\/span><\/h2>\n
