Where are you from? manfaat metronidazole untuk ayam Lehnert explains that the subtlety comes into play because the state of a pulse is specified by two numbers – the real and imaginary components. These two numbers obey the uncertainty principle – either can be measured with arbitrary precision but if both are measured simultaneously, the measurement itself introduces noise that is at least as large as the vacuum fluctuations. But for a demonstration of entanglement, the team must measure the correlations both in the real part and in the imaginary parts and it did so by measuring both simultaneously. “As such we must carefully characterize the noise added by the measurement itself. Having done so, we can show that the second and third pulses are entangled,” says Lehnert. According to him, the team has a high degree of confidence that the oscillator and the microwave pulse are entangled each time the experiment is carried out.
