There are two ways to do this:By integrating a QKD signal onto an existing deployed fibre (which is carrying classical data channels) using wavelength division multiplexing (WDM), with one of our Multiplexed (MU) QKD systems.By using dedicated fibre and deploying our Long-Distance (LD) or Flexible (LE) QKD systems.Toshiba\\u2019s Multiplexed QKD systems include filters for simple integration into existing fibre networks and data services: all user traffic can be passed through the unit without requiring additional multiplexing hardware.The schematic shows an example use case, with an AES encryptor obtaining keys from a Multiplexed QKD system to secure high-bandwidth data streams.\"}},{\"@type\":\"Question\",\"name\":\"What are the security implications of quantum computing?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"While it would take a conventional computer thousands of years to crack the encryption methods securing much of the web today, a sufficiently powerful (or cryptographically relevant) quantum computer would be able to decrypt the data in minutes.
