Quantum computing uses quantum phenomena to solve problems beyond the capabilities of classical computers. It has a profound impact on security and industry.

What is quantum computing?

Quantum computing Quantum computing is a new generation of computing technology that uses principles of quantum physics – such as superposition and entanglement – to solve highly complex computational problems. Unlike classical computers, which operate with bits (0 or 1), quantum computers use qubits, which can exist in multiple states at the same time. This dramatically increases computational power and opens new possibilities in encryption, simulation, optimization, and machine learning.

How quantum computing appears in practice?

Real-world examples and scenarios:

• Decrypting complex encryption algorithms – quantum computers could break today’s cryptographic standards in hours instead of years.
• Simulating molecules and materials – which enables advanced research in pharmaceuticals, chemistry, and nanotechnology.
• Optimalization of routes and logistics – which accelerates planning in transportation, manufacturing or energy.
• Risk analysis in banking – running simulations and calculations that are currently too resource-intensive.
• Advanced AI and machine learning – enabling new models for working with large-scale data.

Quantum computers are not yet widely accessible to businesses, but development is progressing rapidly. For cybersecurity, this means that current encryption algorithms may become breakable in the near future – and organisations should prepare for this shift.

How is quantum computingem different from related terms?

• Quantum computer vs. classical computer
  • Classical: uses bits (0/1).
  • Quantum: uses qubits (multiple states simultaneously through superposition).
• Quantum computing vs. post-quantum cryptography
  • Quantum computing: the computational technology.
  • Post-quantum cryptography: cryptographic protections designed to withstand attacks by quantum computers.

Why this matters:
Many companies focus only on current threats. Quantum computers represent a future risk to the entire encryption infrastructure – so it’s critical to distinguish between the technology itself and the defensive measures against it.

How does the quantum computing posoudit nebo řešit ve vaší firmě

Konkrétní kroky:

1. Zmapujte, kde a jaké šifrování ve firmě používáte.
2. Sledujte vývoj v oblasti postkvantové kryptografie.
3. Zvažte přechod na tzv. „kvantově odolné“ algoritmy (např. NIST standardy).
4. Zajistěte, aby vaše data byla zálohována a chráněna proti budoucím hrozbám.
5. Vzdělávejte vedení a odpovědné pracovníky – kvantová hrozba není sci-fi.

Proč se tím zabývat už teď:
Kvantové počítače zatím nejsou masově nasazeny, ale když přijdou, dopad na digitální bezpečnost může být okamžitý. Firmy, které budou připravené, získají náskok. Ty ostatní budou hasit důsledky. Kvantové výpočty mění pravidla hry – včasné plánování je klíčem k digitálnímu přežití.
