Abstract
The paper introduces the quantum circuit C*-algebra net, which combines C*-algebra neural networks with quantum circuits.
Key highlights:
- C*-algebra is a generalization of the space of complex numbers, allowing the representation of quantum gates as weight parameters in a neural network.
- The quantum circuit C*-algebra net consists of multiple quantum circuits, which can be either independent (commutative C*-algebra net) or interacting (noncommutative C*-algebra net).
- The interaction among circuits enables them to share information, leading to improved generalization performance in machine learning tasks.
- As an application, the quantum circuit C*-algebra net is used to encode classical data into quantum states, enabling the integration of classical data into quantum algorithms.
- Experiments demonstrate that the interaction among circuits significantly improves performance in image classification tasks, and the encoded quantum states can be used in downstream quantum machine learning.
