Quantum Computing Systems 101 for IT Leaders
I. Introduction: Why Quantum Matters Now Over the past seven decades, computing has evolved from bulky vacuum tubes to microchips smaller than a fingernail. Yet, as classical computers reach the physical limits of transistor miniaturization, the world is turning toward a new paradigm — quantum computing . Quantum computing systems represent a complete shift in how information is processed. Instead of bits that can only be 0 or 1, quantum computers use qubits , which can exist in multiple states at once. This allows them to perform certain types of computations exponentially faster than classical systems. For IT leaders and developers , understanding quantum computing is no longer optional. As cloud providers integrate quantum capabilities and industries explore real-world use cases, professionals who grasp the fundamentals today will shape the digital infrastructure of tomorrow. II. The Fundamentals of Quantum Computing 1. Classical vs Quantum Logic In classical compu...
