As of October 26, 2026, researchers are highlighting the transformative potential of quantum computing to solve complex industrial optimization challenges. Global companies are racing to reach one million qubits within five years to address bottlenecks in AI and secure financial data.
Why it matters
Advanced quantum systems could potentially crack current prime factorization-based encryption in days rather than millions of years, necessitating a transition to quantum-resistant security. Simultaneously, these machines excel at analyzing thousands of scenarios at once to optimize big data.
Quantum chips operate at temperatures near absolute zero at -273°C to maintain superposition and entanglement states. Each device currently costs between 10 billion and 100 billion Korean won to manufacture.

The details
Quantum computers utilize qubits in superposition and entanglement to perform computations while employing error correction to self-correct processing mistakes. While they can perform advanced calculations, current blockchain technology like Bitcoin remains resistant to these decryption capabilities.
Timeline
Early room-sized computers existed in the 1940s.

The Tech Race
The development of quantum hardware represents a move beyond classical silicon-based computing toward a paradigm capable of replacing standard prime factorization-based encryption. This transition positions companies to dominate the next generation of cryptographic and big-data infrastructure.
Financial institutions will eventually mandate a transition to quantum-resistant encryption systems, likely requiring users to update security software. Users can expect these systems to improve the speed of complex data processing tasks while hardening digital assets against new decryption threats.
The takeaway
Quantum computing is rapidly moving from a theoretical concept to an industrial tool that will soon necessitate a total overhaul of global digital security. Organizations and individuals should prepare for the transition to quantum-resistant encryption protocols within the next five years.
