Here, \( i \) represents the imaginary unit, which satisfies \( i^2 = -1 \). This expression is a combination of a complex fraction and an imaginary number. It involves dividing 1 by the sum of 1 and the imaginary unit \( i \), and then adding \( i \) to the result.

![1. The probability of detecting a particle is equal to \( z^*z \), where \( z \) is called the probability amplitude and \( z^* \) is its complex conjugate.
2. To determine the probability amplitude for a process that can be viewed as taking place in a series of steps, such as propagation of a photon from a light source to a beam splitter, transmission at the beam splitter, and propagation to a photodetector, we multiply the probability amplitudes for each of these steps:
\[
z = z_a z_b \ldots
\]
3. When there are multiple paths that a particle can take between the source and the detector, the probability amplitude for detecting the particle is the sum of the individual probability amplitudes for the particle to take each path:
\[
z = z_1 + z_2 + \ldots
