Explanatory Answer
'None of the following statements can be inferred except...' implies only one of the given statements can be inferred. According to the passage, 'Keeping time accurately comes with a price. The maximum accuracy of a clock is directly related to how much disorder, or entropy, it creates every time it ticks.' Since quantum computers are, according to the passage, 'devices where both accuracy and temperature are crucial', it can be inferred that quantum computers are likely to produce more heat and, hence, more entropy, because of the emphasis on accuracy. So, option B is the correct answer choice.
The passage only states that the 'arrow of time' may be related to increase in entropy in time keeping. Whether or not the arrow of time has been tested for atomic clocks cannot be inferred based on the information given in the passage.
According to the passage, higher accuracy in timekeeping leads to more heat and more entropy. The converse, however, is not necessarily true. So, option C, too, cannot be inferred.
In the experiment, the clock with a 50-nanometre-thick membrane of silicon nitride has been made to vibrate, using (not producing) electric currents. So, option D is incorrect.
