Quantum computing is one of the most important technological developments that promises computational power beyond classical computers and will shape the future of business. While quantum computers are not yet ready for general use in 2026, the rapid progress in research and development makes it imperative for businesses to start preparing now.
What Is Quantum Computing?
While classical computers process data as 0s and 1s, quantum computers use units called qubits. The unique properties of qubits include:
Superposition
- A qubit can exist in both 0 and 1 states simultaneously
- This property exponentially increases parallel computing capacity
- N qubits can represent 2^N states at the same time
Entanglement
- Two qubits can be linked to share information instantly
- This property is revolutionizing the solution of complex problems
- Provides instantaneous correlation regardless of distance
Quantum computers have the potential to perform calculations in minutes that would take classical computers millions of years.
Potential Business Impacts
Sectors where quantum computing has transformative potential:
Finance and Banking

Impact on Cryptography
One of the most debated effects of quantum computing is the threat to current encryption systems:
Current Threats
- RSA and ECC: Will become breakable with Shor's algorithm
- Symmetric encryption: Security level halved by Grover's algorithm
- Digital signatures: Current infrastructure at risk
Post-Quantum Cryptography
Preparations against these threats have accelerated:
- NIST standards: Post-quantum cryptography standards published in 2024
- Hybrid approaches: Combined use of classical and post-quantum algorithms
- Quantum Key Distribution (QKD): Communication secured by the laws of physics
- Cryptographic agility: Systems' ability to quickly switch between algorithms
Businesses need to prepare today against "harvest now, decrypt later" attacks.
