Quantum Era: Limitations of Quantum Algorithms and Quantum AI for Business

Quantum computing has entered a critical transition phase – from experimental promise to real-world testing. Yet between bold claims and practical impact lies a nuanced reality. We will go through the fundamentals of quantum computing and quantum algorithms, highlighting the principles that distinguish them from classical methods. We will then explore the current landscape of quantum algorithms and quantum AI, reviewing both successful applications and cases where quantum approaches have not met expectations. With an emphasis on business relevance, we will examine concrete use cases across optimization, finance, logistics, and machine learning, separating genuine potential from hype. Finally, we will discuss what companies can realistically achieve today, what bottlenecks remain, and how academia and industry can collaboratively shape the next steps in the quantum era.
