    摘要: Arbitrary quantum information is input. The information of a quantum two-state system is acquired as a qubit by performing a computation in consideration of a physical system. The acquired qubit is encrypted. A quantum system having signature information for guaranteeing that the qubit is really transferred from a sender to a recipient is added to the encrypted qubit. The qubit to which the quantum system having the signature information is added is further encrypted. In this manner, an arbitrary quantum state can be encrypted and transmitted without letting the sender and recipient share an entangled pair of qubits in advance.

    摘要: An image display apparatus which is subjected to getter flashing during manufacturing, for the purpose of increasing the degree of vacuum in the air-tight container thereof, is provided with a getter scattering prevention member comprised of a plurality of getter scattering prevention walls. The getter scattering prevention walls prevent getter material from scattering to the image display portion of the image display apparatus, while allowing for smooth conductance of gas in the air-tight container during evacuation. Thus, evacuation by the getter can be further improved by increasing the area to which getter adheres to, deterioration of the image quality can be prevented by not allowing getter to adhere to the image display portion, the air-tight container can be evacuated in a shorter time, irregularities in brightness of the screen due to uneven pressure within the display portion can be done away with, and a higher degree of vacuum can be attained. Consequently, an image display apparatus with good image quality and a long life expectancy is provided

    摘要: An apparatus for generating a quantum state of a two-qubit system including two qubits, each qubit being represented by a particle which invariably travels through one of two paths, includes a quantum gate composed of an interferometer for implementing an-interaction-free measurement. The apparatus receives two particles having no correlation and generates a Bell state with asymptotic probability 1. A Bell measurement of a state of a two-qubit system is performed by observing a quantum gate composed of the interferometer after the quantum gate has processed the state and selecting the state from the Bell bases. An approximate fidelity of a quantum gate composed of the interferometer is calculated, if an absorption probability with which a first particle absorbs a second particle in the interferometer is less than 1, under the condition that the number of times the second particle hits beam splitters in the interferometer is sufficiently large.
