Abstract: The present invention relates to the architecture of a quantum RAM, a method for using classical data in quantum computing by inputting the classical data as quantum data, and a system and method of operating a quantum database using the architecture. Quantum computing can achieve an exponential speed-up in some applications using a large parallel process provided by a quantum database in which information can be superposed. The present invention proposes an efficient quantum database architecture and protocol that can record and search for classical information with a quantum circuit.

Abstract: Provided is a failure recovery method in a non-revertive mode of an Ethernet ring network. In an Ethernet ring network, link priorities between nodes or node priorities are determined based on media access control (MAC) addresses and the nodes having blocked ports are determined after failures are recovered from based on the priorities so that the blocked ports can be distributed.

Abstract: A method of simulating a quantum state using a quantum computer is provided. The method includes simulating a quantum state of a target molecule using the quantum computer, measuring a Hamiltonian in a simulated quantum state of the target molecule, calculating energy from the Hamiltonian measurements, and calculating a ground state and ground energy of the target molecule through an optimization process of deriving a lowest energy state by adjusting parameters that determine the quantum state of the target molecule, wherein simulating of the quantum state is performed with the configuration of a quantum circuit in which one quantum bit (qubit) is assigned to a pair of spin orbitals.
