Quantum Programming: An In-Depth Introduction and Framework Comparison
Quantum programming is an emerging discipline that challenges developers to think beyond classical bits and deterministic algorithms. Instead of manipulating binary 0s and 1s, quantum programmers work with qubits that can exist in multiple states at once and harness phenomena like superposition and entanglement to perform computations in fundamentally new…

How Quantum Could Break Through Amdahl’s Law and Computing’s Limits
Amdahl’s Law teaches us a humbling lesson about the limits of classical computing: there is always a portion that resists parallel speedup, chaining us to diminishing returns. We’ve coped by clever engineering – making that chain as short as possible – but not broken it. Quantum computing offers a bolt…

Entropy-Driven Photonic Quantum Computing: A Critical Look at QCI’s Approach
Quantum Computing Inc. (QCI) has introduced an unconventional paradigm in quantum computing called Entropy Quantum Computing (EQC). Unlike the standard approach of isolating qubits in pristine, ultra-cold environments, QCI’s method intentionally embraces environmental noise and loss as part of the computation. Their quantum processors, optical devices operating at room temperature,…
