Abstract: A quantum device includes a quantum chip and a holder. The holder includes a pedestal, a recess portion formed in a main surface of the pedestal so as to be opposed to the quantum chip, and a suction tube provided such that in the recess portion, a suction opening is positioned in a bottom surface of the quantum chip.

Abstract: Receivable channels in a program guide G used for selecting a program are arranged using the longitudinal axis of the program guide G itself as a time base and using the horizontal axis as a channel axis. A channel being currently viewed is disposed at the left end. From the right side of the channel, the other channels are arranged in decreasing order of the viewing frequency from left to right, and programs of the other channels are disposed along the time base.

Abstract: A program information acquisition apparatus includes a program information acquisition unit, a program information accumulation unit, and a program information acquisition determining unit. In this configuration, a start of an acquisition operation by the program information acquisition unit is determined based on an information accumulation status of the program information accumulation unit. Thus, program information distributed from a desired reception target can be accumulated as the latest information as much as possible. Since unneeded program information is not acquired, program information acquisition with high energy saving effects is made possible.
