Definition (English)
The often-ignored cost of loading classical data into quantum states for quantum machine learning. Encoding N classical data points into quantum states can require O(N) quantum gates, eliminating any exponential speedup the quantum algorithm promises. This overhead — sometimes called the 'input problem' — means quantum ML advantage exists only for data already in quantum form (like molecular simulations) or for problems where the encoding cost is amortized over many queries.
