Abstract
Described herein are techniques related to implementation of a quantum key distribution (QKD) scheme by a photonic integrated circuit (PIC). For example, the PIC is a component in a wireless device that is used for quantum communications in a quantum communications system.
Claims28
A photonic integrated circuit (PIC) that utilizes a quantum key distribution (QSD) scheme comprising:
- a hybrid silicon laser that is configured to produce light signals;
- a polarizer that receives the light signals, the polarizer is configured to change polarization of the light signals into a beam that includes a well-defined polarization;
- a modulator coupled to the laser array, the modulator modulates the beam for transmission through a quantum channel.
A wireless device that utilizes a quantum key distribution (QSD) scheme comprising:
- a photonic integrated circuit (PIC) that includes:
- a laser array that is configured to produce light signals;
- a polarizer that receives the light signals;
- a modulator coupled to the laser array, the modulator modulates the polarized light signals for transmission in a quantum channel;
- a processor configured to the PIC.
