# Framework: from Classical to Quantum

In the above figure, on the left-hand, it is the design framework for classical hardware (HW) accelerators. The whole procedure will take three steps: (1) pre-processing data, (2) accelerating the neural computations, (3) post-processing data.

Similarly, on the right-hand side, we can build up the workflow for quantum machine learning. It takes 5 steps to complete the whole computation: (1) PreP pre-processing data; (2) UP data encoding onto quantum, that is quantum-state preparation; (3) UN neural operation oracle on quantum computer; (4) M data readout, that is quantum measurement; (5) PostP post-processing data. Among these stpes, (1) and (5) are conducted on classical computer, and (2-4) are conducted on the quantum circuit.

# Quantum Advantage Achieved for Neural Computation

When bridging the machine learning and quantum computing, the first and foremost question is why we need quantum computer for machine learning? We give the answer that the neural network computation on quantum computer can achieve quantum advantage. That is, for the cost complexity of O(2^N) on classical computer, a well-designed quantum implementation can reduce the cost to O(N^2). The following figure reports the comparison results for the core component in neural network, the neural computation layer.

# QuantumFlow Framework

The quantum advantage is achieved by co-design the neural network and quantum circuit. In the paper, we propose the first co-design framework, namely QuantumFlow, to design quantum-friendly neural network and optimize quantum circuit leveraging the network’s property to reduce the cost complexity from O(2^N) to O(N^2). We demonstrate QuantumFlow in the following figure, and please refer to our NCOMMS paper for detailed info.

# QF-Nets on MNIST

The quantum-friendly QF-Nets achieves over 90% accuracy on different subsets from MNIST. In our Demo, we demonstrate how to map QF-Nets for {3,6} sub-dataset from MNIST onto quantum circuits on quirk with 16 qbits, whose accuracy is 95.73%.
