摘要： The invention concerns a method and device for checking tightness of containers, housings and similar test objects (15). The test object (15) is subjected to a pressurized test gas. If a leak (28) is present, test gas escapes from the text object (15) and is exposed in a test chamber (18) to an intensity-modulated electromagnetic wave field emitted by a laser (1). The wave field contains frequency components which are absorbed by the test gas to produce a photo-acoustic signal indicative of the presence of a leak. To facilitate a quantitative tightness examination even using a longitudinal multimode laser with several laser modes which can be absorbed by the test gas, it is proposed according to the present invention that the temperature of the laser (1) should be set to a reference value and the excitation power of the laser should be kept at a constant mean level, so that the photo-acoustic signal can be measured and evaluated as a measure of the test gas concentration in the test chamber and/or of the size of the leak from the test object. To improve measuring accuracy, a reference chamber (5) with a predetermined test gas concentration is in addition exposed to the intensity-modulated wave field emitted by the laser (1); the photo-acoustic signal (6) produced in the reference chamber (5) is then used either for standardization purposes for when the test gas concentration in the test chamber (18) is determined, or for adjusting the reference temperature value (T.sub.ref) of the laser (1) to a predetermined working point.

摘要： A method for interaction-free entanglement of quantum bits in quantum computers, in which the quantum bits to be entangled are available in the state ψ44 with arbitrarily real phases φ and θ as an elementary quantum system. The two quantum bits (1) and (2) are localized in spatial regions (6) and (6′) and surrounded by switchable sheaths (7) and (7′) preferably a superconductor with the jump temperature TSU. The switchable sheaths, in the activated state, completely displace a global, homogeneous magnetic field Bz from the spatial regions (6) and (6′). In the inactivated state, the switchable sheaths do not shield the spatial regions (6) and (6′). If the switchable sheaths are switched from the activated state into the inactivated state while observing the boundary condition (R3), as a result of this, the two quantum bits (1) and (2) are transferred into the entangled state ψ.
