    • To identify errored bits in a binary data set, an ordered plurality of modulo-2 summations of respective selections of the data-set bits are compared with a target syndrome. The selections of data-set bits are defined by the connection of sum nodes to variable nodes in a logical network of nodes and edges where each variable node is associated with a respective data-set bit and each sum node corresponds to a respective modulo-2 summation. Any sum node for which the corresponding summation of selected data-set bits is found to be inconsistent with the target syndrome is identified as errored. Predetermined patterns of errored sum nodes are then looked for to identify one or more associated errored data-set bits. The identified errored data-set bits can then be flipped to correct them.

    • A method is provided of creating an end-to-end entanglement (89) between qubits in first and second end nodes (81L, 81R) of a chain of optically-coupled nodes whose intermediate nodes (80) are quantum repeaters. Local entanglements (85) are created between qubits in neighbouring pairs in the chain through interaction of the qubits with light fields transmitted between the nodes. A trigger (82) propagated along the chain from one end node (81L), sequentially enables each quantum repeater (100; 210) to effect a top-level cycle of operation. In each such cycle, a repeater (80) initiates a merging of two entanglements involving respective repeater qubits that are at least expected to be entangled with qubits in nodes disposed in opposite directions along the chain from the repeater. A quantum repeater (80) adapted for implementing this method is also provided.
    • 提供了一种在其中间节点(80)是量子中继器的光耦合节点链的第一和第二端节点(81L,81R)中的量子比特之间产生端到端纠缠(89)的方法。 通过量子位与节点之间传输的光场的相互作用,在链中的相邻对中的量子位之间产生局部纠缠(85)。 沿着链从一个端节点(81L)传播的触发器(82)顺序使得每个量子转发器(100; 210)能够实现顶层操作循环。 在每个这样的周期中,中继器(80)启动两个缠结的两个纠缠,这两个纠缠涉及相应的中继器量子位,这些纠错器量化位置至少预期与沿着来自中继器的链路沿相反方向布置的节点中的量子位相互纠缠。 还提供了适于实现该方法的量子中继器(80)。

    • QKD receiving apparatus is provided with an alignment-correction system for correcting misalignment of a quantum signal received at an optical port of the apparatus relative to a quantum-signal detector of the receiving apparatus. The alignment-correction system comprises a misalignment measuring subsystem for making multiple different misalignment measures, and a misalignment compensation subsystem for adjusting the relative alignment of the quantum signal and quantum-signal detector in dependence on the misalignment measures made. The misalignment measuring subsystem comprises an alignment-beam source, an alignment-beam detector arrangement, and optical components for guiding an alignment beam from the alignment-beam source to the optical port, and for guiding the alignment beam, after external retro-reflection at a cooperating QKD transmitting apparatus from the optical port to the alignment-beam detector arrangement.

    • A method and apparatus (70) are provided for creating an entanglement between two qubits situated in spaced nodes (71, 72) and coupled by an optical channel (75). One node (71) supports a plurality of qubits (73) and is arranged to pass a respective light field through each qubit and on into the optical channel (75), so as to produce a train (78) of closely-spaced light fields on the optical channel (75). The other node (72) supports a target qubit (74) and is arranged to receive the light-field train (78), to allow each successive light field to pass through, and potentially interact with, the target qubit (74) while the latter remains un-entangled, and to thereafter measure each light field to determine whether the latter has been successfully entangled. Upon the second node (72) determining that the target qubit (74) has become entangled, it inhibits the interaction of further light fields with the target qubit.
