The provided text, "Quantum Computing Inconveniences: September 2025," offers a comprehensive overview of the significant challenges currently facing the field of quantum computing. It primarily focuses on the inherent difficulties stemming from quantum decoherence and quantum noise, which corrupt quantum states and necessitate complex mitigation strategies. The source further highlights the "tyranny of numbers" in scaling quantum processors, explaining the crucial distinction and resource overhead between noisy physical qubits and reliable logical qubits required for error correction. Additionally, it addresses the probabilistic nature of quantum measurement, requiring numerous "shots" to derive meaningful results, which impacts algorithmic efficiency and cost. Finally, the document details the extreme economic costs associated with developing and operating quantum computers, encompassing high capital expenditures and significant operational overheads.
