Abstract: An information processing apparatus including a first system having first acquisition circuitry and first output circuitry and a second system having second acquisition circuitry, third acquisition circuitry, and second output circuitry. The first acquisition circuitry may acquire sensor information regarding an environment of a predetermined mobile object by at least one or more sensors installed in the mobile object. Also, the first output circuitry may output auxiliary information for assisting determination of control information for controlling an action of the mobile object. Further, the second acquisition circuitry may acquire partial sensor information from at least one sensor of the one or more sensors, the third acquisition circuitry may acquire the auxiliary information output by the first output circuitry, and the second output circuitry may output control information, using at least part of the partial sensor information or the auxiliary information.

Abstract: Described is a method of setting up a plurality of quantum communications links, forming a quantum network providing provably secure communications and internet services over intercontinental distances without requiring direct line of sight communication or the intermediate use of the entanglement resource of satellites. Also described is a quantum communicator device for use in this method. Two or more quantum memory units are disposed at a first location, an entangled link is set up between at least two of the quantum memory units, at least one of the quantum memory units sharing in the entangled link is physically transported to a second location. The quantum communicator device comprises communications nodes, an optical interface to set up entanglement to other devices and storage nodes, each node in the form of a quantum memory unit capable of storing quantum information for a desired length of time, i.e. weeks or longer.

Abstract: Described herein is a Quantum Computing device comprising a first and a second square patch of qubits, each of the first and second square patch of qubits representing a logical qubit and being in a joint quantum state corresponding to a surface code, the surface code having a distance of two or more. The first and second square patch of qubits have a side-length equal to the distance plus one qubits. The device furthermore comprises one or more chain of qubits prepared in a joint GHZ state serving as a data bus. The chain of qubits neighbors both the first and the second square patch of qubits and has a length equal to or greater than the sum of the two side-lengths.

Abstract: A system for locating errors for quantum computing includes an interface, a shift array, a comparison block, a tree pipeline, and a serializer. The interface is configured to receive a set of quantum bit values, wherein the set of quantum bit values comprise a subset of quantum bit values in a quantum bit array. The shift array is configured to store a prior set of quantum bit values read from identical quantum bit locations at a prior time corresponding to the set of quantum bit values. The comparison block is configured to identify differences between the set of quantum bit values and the prior set of quantum bit values. The tree pipeline configured to rank the differences identified. The serializer is configured to serialize the differences identified in order by rank.
