Abstract: A network element in a quantum network receives a hybrid frame including a classical header and a quantum payload. The network element processes the classical header for a length of time and generates a new classical header. The network element drops a portion of the quantum payload based on the length of time spent processing the classical header and updates the hybrid frame to include the new classical header and the quantum payload without the dropped portion.

Abstract: A method is provided for deterministically generating a photonic resource state for computational quantum computing. The method includes producing a sequence of emitted photonic qubits. The sequence of emitted photonic qubits is directed to an optical circulator of a passive entanglement component. The passive entanglement component includes the optical circulator, a delay line, and a Controlled-Z (CZ) gate. Each photon in the sequence of emitted photonic qubits is reflected at the end of the first delay line to generate a sequence of reflected photonic qubits after a predetermined time delay. The CZ gate entangles the sequence of emitted photonic qubits with the sequence of reflected photonic qubits. The optical circulator directs a resource state generated from the sequence of reflected photonic qubits entangled with the sequence of emitted photonic qubits to an output of the passive component. The resource state is emitted as a sequence of entangled photonic qubits.

Abstract: A method of managing communication over a quantum channel. The method includes generating a first set of quantum channel codes configured to encode a message to obtain a quantum encoded message, supplying the first set of quantum channel codes to an encoder, generating a second set of quantum channel codes configured to decode the quantum encoded message, and supplying the second set of quantum channel codes to a decoder that is configured to operate with encoder across a channel, wherein the first set of quantum channel codes and the second set of quantum channel codes are derived using a machine learning model.

Abstract: A network element receives a classical header for a quantum payload, and processes the classical header to determine a destination endpoint for the quantum payload. The network element generates a new classical header for the quantum payload based on the destination endpoint. The network element sends the new classical header to a next hop ahead of the quantum payload at a time based on a number of hops between the network element and the destination endpoint.
