Quantum cryptography transmitter for secure communication
The patent US12074969B2 describes a transmitter and receiver device designed for secure communication utilizing quantum cryptography. The transmitter device generates light pulses composed of photons, which are polarized and encoded with a quantum key. It employs optical filters to purify these photons, creating a coherent light source for transmission over an optical channel. The device features multiple optical channels for polarization, a chip adapter for reading cards, and a status display with six LEDs to indicate transaction statuses. Additionally, it includes physical docking mechanisms to ensure alignment with the receiver device, which is crucial for maintaining secure communication.
The receiver device is equipped with a dichroic mirror to receive and process the combined light pulses from the transmitter. It adjusts polarization detection optics to facilitate quantum key exchange and ensure proper alignment for optimal communication. The device also features alignment rods for physical docking and dock locks to prevent misalignment during operation. A data communication channel allows for interaction between the transmitter and receiver, enabling the sharing of encrypted user information, such as payment card details. The method outlined in the patent includes steps for recognizing the transmitter, checking polarization alignment, and securely sharing the quantum key, with visual indicators provided by the status LEDs throughout the process.
