    Abstract: A measurement-device-independent quantum key distribution (MDI-QKD) network includes a plurality of user nodes connected to untrusted relay node that performs Bell-state measurements on qubits transmitted by the user nodes. The relay node contains a calibration laser that serves as a wavelength reference for the user nodes. The output of the calibration laser is split into two wavelength-calibration signals, which are transmitted to a pair of user nodes via optical fiber. At each user node, a laser diode used to generate weak coherent pulses is injection-locked with the wavelength calibration-signal, thereby ensuring that the user nodes generate photonic qubits with the same wavelength. The embodiments may be implemented with any encoding scheme compatible with MDI-QKD, such as polarization encoding and time-bin phase-encoding. No auxiliary connections between the user nodes are needed, allowing the MDI-QKD network to be scaled up to many users.

    Abstract: Methods, systems, and devices for a quantum Internet router are described. A first network node (e.g., a quantum Internet router) may receive a command from a second network node by a digital information channel indicating a destination network node, a Bell State Measurement (BSM), and a pair of entangled particles establishing a quantum entangled channel between the first and second network nodes. The first network node may determine a third network node to forward the command based on a forwarding table and generate a second BSM based on a QSR operation and a second pair of entangled particles establishing a quantum entangled channel between the first and third network nodes. The first network node may forward, to the third network node, a command indicating the destination network node, the second BSM, and the second pair of entangled particles.

    Abstract: A method for quantum-key-distribution-based encrypted data transmission in an optical/radio-access network, having a plurality of end nodes, includes, at a first node of the network: (a) via an optical quantum channel, exchanging photonic qubits with a second node, wherein the photonic qubits are processable to derive therefrom an initial key such that each of the first and second nodes have a copy of the initial key, (b) via a classical channel, exchanging a series of encrypted keys with the second node, wherein a first encrypted key is encrypted by the initial key, and each subsequent encrypted key is encrypted by a preceding encrypted key, and (c) via the classical channel, exchanging encrypted data with the second node, wherein the encrypted data is encrypted by a last encrypted key in the series of encrypted keys. One, but not both, of the first and second nodes is an end node.

    Abstract: A server device is provided for authenticating client devices on a communication network. The server device includes a transceiver configured for operable communication with at least one client of the communication network, and a processor including a memory configured to store computer-executable instructions. When executed by the processor, the instructions cause the server device to receive an authentication request from a client device, generate a seed for a first key for the client device if the client device authenticates, transmit the seed for the first key to the client device, receive a hash of the first key from the client device, and validate the first key based on the hash of the first key.

    Abstract: A node for a quantum key distribution (QKD) network includes an optical input that receives an optical pulse from a hub of the QKD network and an optical splitter that splits the optical pulse into an optical timing pulse and a pre-qubit pulse. The node also includes a qubit encoder controllable to encode the pre-qubit pulse into a photonic qubit; a qubit trigger circuit that controls, based on the optical timing pulse, the qubit encoder while the pre-qubit pulse propagates through the qubit encoder; and an optical output that transmits the photonic qubit to the hub.
