Abstract: A first node of a network includes a quantum receiver, a classical transceiver, and an initial-key generator that cooperate with a second node of the network to receive an initial key via the quantum receiver. The first node includes a key-series generator that (i) decrypts, with the initial key, a first encrypted key of a series of encrypted keys to generate a first unencrypted key of a respective series of unencrypted keys and (ii) decrypts each subsequent encrypted key of the series of encrypted keys with a preceding unencrypted key of the series of unencrypted keys to generate a subsequent unencrypted key of the series of unencrypted keys. The first node includes one or both of a decryptor and an encryptor. The decryptor decrypts encrypted data using a last unencrypted key of the series of unencrypted keys. The encryptor encrypts unencrypted data using the last unencrypted key.

Abstract: Methods, systems, and devices for quantum key distribution (QKD) in passive optical networks (PONs) are described. A PON may be a point-to-multipoint system and may include a central node in communication with multiple remote nodes. In some cases, each remote node may include a QKD transmitter configured to generate a quantum pulse indicating a quantum key, a synchronization pulse generator configured to generate a timing indication of the quantum pulse, and filter configured to output the quantum pulse and the timing indication to the central node via an optical component (e.g., an optical splitter, a cyclic arrayed waveguide grating (AWG) router). The central node may receive the timing indications and quantum pulses from multiple remote nodes. Thus, the central node and remote nodes may be configured to communicate data encrypted using quantum keys.

Abstract: Systems, methods, and devices disclosed herein contemplate client updates to traffic filter tables that control delivery of network traffic from an access point to the client over a multi channel wireless network. The client may update the traffic filter table whenever: (i) an application on the client initiates the request; (ii) an application matching a secondary channel requirement in a look-up table is opened or closed; (iii) data characteristics matching the secondary channel requirement in the look-up table are detected or removed; (iv) data usage of the client meets or exceeds a predetermined threshold; (v) data usage of the client falls below a predetermined threshold; and/or (vi) a specified period of time has passed.

Abstract: A radio access network (RAN) node is provided for a small cell of a wireless access network having a coaxial line. The RAN node includes an input operably coupled with the coaxial line and an output configured to wirelessly communicate with at least one user equipment device within an operable vicinity of the wireless access network. The RAN node further includes a transmission path configured to (i) connect the input to the output, and (ii) communicate a first radio frequency (RF) signal from the input to the output, and a reception path separate from the transmission path, and configured to (i) connect the output to the input, and (ii) communicate a second radio frequency (RF) signal from the output to the input. The RAN node is configured to dynamically switch between the transmission path and the reception path in response to a tone received from the wireless access network.

Abstract: A coherent optical injection locking (COIL) apparatus generates multiple optical source outputs from a single optical source generated by a parent laser. The COIL apparatus includes a plurality of optical source generators each having a child laser, of lesser performance than the parent laser, that is injection locked to the single optical source. The optical source generators may have one or both of a shared configuration and a cascaded configuration that replicates the single optical source, or a single wavelength of the single optical source when it is a comb source.
