The Hidden Bottleneck in Quantum Machine Learning: Getting Data into a Quantum Computer
The article discusses the challenges of loading classical data into quantum computers for machine learning. It highlights that quantum computers cannot directly read classical bits, necessitating the embedding of data into quantum states. This process becomes increasingly complex as data size and complexity grow, with no efficient universal method currently available.
- ▪Quantum computers operate using qubits, which differ fundamentally from classical bits.
- ▪The process of embedding classical data into quantum states is a significant bottleneck in quantum machine learning.
- ▪As the size and complexity of data increase, the cost of preparing quantum states can grow exponentially.
