摘要： Systems and methods are provided for performing a quantum gate operation. A first classical control parameter, configured to tune an associated frequency of a first qubit, is adjusted from a first value to a second value. The first value is selected such that the first qubit is tuned far from a characteristic frequency of an associated resonator, and the second value is selected such that the first qubit is tuned near to the characteristic frequency of the resonator. A second classical control parameter, configured to tune an associated frequency of a second qubit, is adjusted from a third value to a fourth value. The third value is selected such that the second qubit is tuned far from the characteristic frequency of the resonator. The first classical control parameter is returned to the first value. The second classical control parameter is returned to the third value.

摘要： Prior approaches have delivered O2 to a subject by inhalation, but the relationship between local signal changes and metabolism has been complicated by H217O created in non-cerebral tissues. During a brief pulse of 17O2 inhalation, this arterial input function for H217O is negligible due to convective transport delays. Additional delays in the arterial input function due to restricted diffusion of water makes pulsed inhalation of 17O2 even more effective. Accordingly, ventilator system are provided to deliver 17O2 as a brief pulse to a subject. Subsequent MR imaging demonstrates delayed appearance of H217O in the cerebral ventricles, suggesting that the arterial input function of H217O is delayed by restricted water diffusion in addition to convective transit delays. Delivery as a brief pulse therefore offers significant advantages in relating MR signal changes directly to metabolism.
摘要翻译：以前的方法通过吸入将O2传递给受试者，但是在非脑组织中产生的H217O，局部信号变化和代谢之间的关系已经复杂化。在17O2吸入的短暂脉冲期间，H217O的这种动脉输入功能由于对流运输延迟而可忽略不计。由于水分扩散引起的动脉输入功能的额外延迟使得17O2的脉冲吸入更有效。因此，提供呼吸机系统以将作为短暂脉冲的17O2输送到受试者。随后的MR成像显示H217O在脑室中的延迟出现，表明H217O的动脉输入功能除了对流转运延迟之外，受到限制性水扩散的延迟。因此，作为短暂脉冲的交付提供了将MR信号变化直接与新陈代谢相关联的显着优点。

摘要： A gas measurement probe for measuring gas tensions in liquid. The probe comprises a tubing having one end adapted for connection to a gas measurement device, such as a mass spectrometer, a gas chromatograph, an infrared spectrometer or a Raman spectrometer, among others. The second end of the probe is provided with a tip having at least one pore formed in it. The pore is filled with a membrane material which eliminates water from entering, but admits low molecular weight gases. These low molecular weight gases may then be identified by the measurement device.
