  • Patent number: 12052351
    Abstract: Information can be transmitted through classical and quantum communication channels in parallel and at rates that enhance secure communication. The quantum communication is scaled to a transmission rate of 10 GHz or more, which matches the rate of classical communication transmission. During transmission of information (e.g., a message) through a classical channel, a quantum channel can transmit quantum key information used to construct a new key (e.g., a new decryption key) from the prior key. As a result, the same key is not reused for decryption and can be discarded after use. Further, a multiplexing system can encode and transmit both classical and quantum communication at the GHz-level transmission rate as a single optical beam, while a demultiplexing can receive and decode the information from the single optical beam.

  • Patent number: 12000329
    Abstract: The present disclosure relates to assemblies for engines such as pre-combustion chamber assemblies for spark ignition engines. It is known to provide a spark ignition engine with a pre-combustion chamber but it can be difficult to provide a system with good knock performance at high speed with high loads while still having reliable ignition at low speed with low load. In particular, at low speed with low load, there may be a relatively high percentage of exhaust gas residuals (EGR) in a pre-combustion chamber which can prevent ignition especially when the ignition timing is retarded during catalyst heating. Aspects of the disclosure aim to alleviate at least to a certain extent the problems of the prior art.
