Abstract: A method and an apparatus for providing a virtual desktop service to provide an optimal virtual desktop service in accordance with distances between virtualization servers and a user are provided. A virtual desktop service suitable for a request of the user is provided to the user so that loads of servers may be dispersed and power usage of the servers may be minimized. That is, in an environment where the virtualization servers that provide the virtual desktop service are locally dispersed, the virtual machines may be allocated to a virtualization server with a shortest network delay based on network distances from the virtualization servers to the user. In addition, after a server power usage amount is predicted in accordance with a virtual machine usage type of the user, a virtualization server may be selected in accordance with the prediction result.

Abstract: A method of moving a magic qubit in logical qubit arrangement architecture based on a checkerboard may include generating a plurality of distilled magic qubits necessary for a predetermined logic operation through a magic state distiller, storing the plurality of distilled magic qubits in a magic qubit repository, primarily moving the stored magic qubit to an area adjacent to a logical qubit block corresponding to a destination through an external bus and an internal bus, and secondarily moving the magic qubit from the area adjacent to the logical qubit block to the destination within the logical qubit block through a temporary bus.
