My university has a quantum information department for research, I'm thinking about joining it and wanted to know if quantum information, quantum communication and cryptography, quantum networking, and room temperature linear-optical quantum computing is a meme. They also do research in Quantum computing and simulation of complex Hamiltonians of physical and chemical structure, Design and simulation of novel quantum materials including new types of topological insulators, Fast quantum search in large databases using high-dimensional quantum walk, Quantum machine learning, Quantum neural networks. Topological manipulation of quantum information, and more. Maybe I'm just crazy but it just sounds like a lot of buzzwords combined
