Abstract: A method and apparatus (80) are provided for routing entanglement building between a selected pairing of interface qubits (82). The qubits of the selected pairing of interface qubits (82) are separately entangled with at least one intermediate qubit (84) by interacting respective light fields with the interface qubits of the selected pairing and using an optical merge arrangement (83) to further interact the light fields with at least one intermediate qubit (84). Where there are multiple intermediate qubits (84) the intermediate qubits are entangled with each other. The or each entangled intermediate qubit (84) is then removed from entanglement.

Abstract: A method is provided of creating an end-to-end entanglement (87) between qubits in first and second end nodes (81, 82) of a chain of optically-coupled nodes whose intermediate nodes (80) are quantum repeaters. Local entanglements (85) are created on an on-going basis between qubits in neighboring pairs in the chain through interaction of the qubits with light fields transmitted between the nodes. The quantum repeaters (80) are cyclically operated with their top-level operating cycles being synchronized. Once every top-level operating cycle, each 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.

Abstract: Various embodiments enable regions of text to be identified in an image captured by a camera of a computing device for preprocessing before being analyzed by a visual recognition engine. For example, each of the identified regions can be analyzed or tested to determine whether a respective region contains a quality associated with poor text recognition results, such as poor contrast, blur, noise, and the like, which can be measured by one or more algorithms. Upon identifying a region with such a quality, an image quality enhancement can be automatically applied to the respective region without user instruction or intervention. Accordingly, once each region has been cleared of the quality associated with poor recognition, the regions of text can be processed with a visual recognition algorithm or engine.

The step of generating the second number is performed starting from public parameters and is independent of the step of generating the first number.

Abstract: An iterative method is provided for progressively building an end-to-end entanglement between qubits in first and second end nodes (91, 92) of a chain of nodes whose intermediate nodes (90) are quantum repeaters. At each iteration, a current operative repeater (90) of the chain merges an entanglement existing between qubits in the first end node (91) and the operative repeater, with a local entanglement formed between qubits in the operative repeater and its neighbor node towards the second end node (92). For the first iteration, the operative repeater is the neighbor of the first end node (91); thereafter, for each new iteration the operative repeater shifts one node further along the chain toward the second end node (92). A quantum repeater adapted for implementing this method is also provided.

Abstract: A processing arrangement of a data communication apparatus is arranged to derive an ordered plurality of modulo-2 summations of respective selections of data bits of a binary data set. The data communication apparatus may either be transmitting apparatus with the processing arrangement serving to determine a target syndrome for subsequent use in error correction, or receiving apparatus with the data processing arrangement being arranged to effect error correction of received data. The processing arrangement effects its selections of bits from the binary data set in accordance with the interconnection of nodes in a logical network of nodes and edges that together define at least a continuum of cells covering a finite toroid. The structuring provided to bit selection by this continuum can be offset by randomness provided by other structures of the network and by the random association of bits of the binary data set with the nodes of the continuum.
