Abstract: A pressure transducer includes a cavity, a first dipolar molecule disposed within the cavity, and a second dipolar molecule disposed within the cavity. The first dipolar molecule exhibits a quantum rotational state transition at a fixed frequency with respect to cavity pressure. The second dipolar molecule exhibits a quantum rotation state transition at a frequency that varies with cavity pressure.
