Quantum neural networks have the potential to achieve unprecedented computational capabilities, as well as to efficiently recognize quantum states, a task inaccessible to classical computers. However, existing approaches that rely on their implementation with qubits are limited by the latter’s poor connectivity.
Danijela Marković’s project qDynnet takes a new approach, which uses parametrically coupled quantum oscillators instead of physically coupled qubits. This will allow for realization of quantum neural networks of unprecedented size, connectivity and tunability. For this, neurons are implemented as ground states of a set of coupled quantum oscillators, and connections between neurons as transitions between these states. In qDynnet project these networks will be experimentally realized with superconducting circuits and used to demonstrate automatic recognition of quantum states.
The qDynnet project will provide the understanding of physics of dynamical connections, and develop new dynamical learning methods, that will serve as a foundation for a whole new family of dynamical quantum networks.
