A method for monitoring the state of a qubit device comprising a chiral nanocrystal includes measuring a voltage, a current, or a magnetic field of the nanocrystal; assigning the nanocrystal a superposition state if the measured voltage, current, or magnetic field is less than a superposition threshold; and assigning a base state value of the nanocrystal if the measured voltage is greater than a base state threshold. The measured voltage, current, or magnetic field corresponds to a clockwise or counter clockwise flow of electrons around the nanocrystal.
