An electro-optic device includes a substrate structure, a first layer, a second layer on the first layer, and a third layer on the second layer. The first layer includes a first thin film lithium-containing (TFLC) electro-optic material and having a first thickness. The second layer includes a second TFLC electro-optic material and has a second thickness. The third layer includes a third TFLC electro-optic material and having a third thickness. Electro-optic structure(s) of the electro-optic device includes the first layer, the second layer, and the third layer. In the electro-optic structure(s), the first layer has a first width, the second layer has a second width, and the third layer has a third width.

Multilayer thin film lithium-containing optical devices

In a general aspect, a photonic quantum network is disclosed. In some implementations, microwave modes and optical modes are generated on first and second quantum processing units (QPUs) by operation of a first transducer device of the first QPU and a second transducer device of the second QPU. The microwave modes are transmitted within the first and second QPUs from the first and second transducer devices to respective first and second qubit devices. The optical modes are transmitted from the first and second QPUs to an interferometer device. By operation of the interferometer device, output signals are generated on respective output channels based on the optical modes from the first and second QPUs. Based on the output signals detected by operation of photodetector devices coupled to the respective output channels, quantum entanglement transferred to the first and second qubit devices by the microwave modes is identified.
