    摘要： A processor includes request issuing units issuing an access request to a storage, a data array including banks holding sub data divided from data read from the storage based on the access request, a switch to transfer the access request to one of the banks, and first and second determination units. The first determination unit determines a cache hit when a tag address included in the access address matches a tag address held therein in correspondence with an index address included in the access address. The second determination unit determines a cache hit when identification information corresponding to a first tag address included in the access address and a second tag address included in the access address, match identification information and second tag address held therein. A cache controller makes access to the data array or storage, based on a determination result of the first or second determination unit.

    摘要： This computation device and method exponentially shortens a computation time of an NP-complete problem or the like mapped into an Ising model by exponentially shortening a computation time of the Ising mode. For each pair of a plurality of slave lasers, by controlling the intensity, the polarization, and the phase of light exchanged between two slave lasers using an attenuator and a wave plate, the magnitude and the sign of pseudo Ising interaction between two slave lasers are implemented. Then, after the plurality of slave lasers arrive at a steady state, by measuring the polarization of light generated by each slave laser with left-handed circular polarization and right-handed circular polarization used as bases, a pseudo spin of each slave laser is measured.

    摘要： An information processing unit and information processing method capable of performing a ground-state search of an Ising model having coefficients of arbitrary values regardless of restrictions on hardware or software is suggested.When a ground state of an original problem, which is an Ising model, or an approximate solution of that ground state is calculated as a solution of the original problem, one or more sub-problems which are Ising models are generated from the original problem and the information processing unit searches the ground state of each generated sub-problem and generates a solution of the original problem based on a solution of each sub-problem obtained from the search; and when types of coefficient values of an Ising model whose ground state can be searched are limited, sub-problems which are Ising models composed of the types of limited values of coefficients are generated.

    摘要： 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.
