Quantum Computing in the 2020s
How qubits are rewriting the rules of computation (2025)
Quantum computers have finally moved from theoretical physics labs to commercial labs worldwide in 2025. This post explores how companies like IBM and Google are turning quantum theory into practical systems that reshape cryptography, optimization problems, and AI training...
"When information can exist in multiple states simultaneously, security protocols need to evolve beyond classical encryption paradigms."
Modern quantum processors leverage superconducting qubits and photonic systems. Companies are now offering cloud-based quantum processors where developers can experiment with quantum algorithms. This opens new possibilities for solving complex problems in minutes rather than decades.
⚛️ Quantum Algorithms
Shor's algorithm is now being optimized for large-scale prime factorization challenges.
⚙️ Hardware Challenges
