Application: Network interface card for quantum computing over classical and quantum communication channels (Patent ID: US20240072908A1)
The patent filed by NVIDIA Corp. discloses a system for enabling quantum computing over classical and quantum communication channels. The system includes a network interface card (NIC) apparatus with an optical receiver, embedded processor, and network switch. The optical receiver receives qubit data through a quantum communication channel, which is then converted into binary bit data by the embedded processor. The network switch outputs the binary bit data through a classical network communication channel.
The NIC apparatus described in the patent includes various configurations and functionalities, such as managing transmission of RDMA packets to HPC systems, converting qubit data to binary bit data based on amplitude or phase data, performing key exchange and handshake protocols, and digital signal processing operations like signal conditioning, chromatic dispersion, and carrier frequency estimation. The system also involves converting channels between quantum and classical communication, managing hop counts for data transmission, and basing processing operations on quantum hop counts. Overall, the patent outlines a comprehensive approach to integrating quantum computing capabilities into existing network infrastructure.
