Quantum States and Probabilities
To understand how quantum gates precisely calibrate the quantum states of qubits in programs, we need a systematic way to represent blended states. To model such states in code, let’s start with a qubit containing seven pentagon qubelets and three inverted triangle qubelets, shown here:
Looking at this qubit, we can deduce the following:
When measured, the pentagon qubelets have a greater chance of being selected than the triangle qubelets; in other words, the qubit is skewed toward collapsing to the idealized state than the idealized state.
Qubelets can be inverted, such as the triangle ones in the figure.
We express these observations for the quantum state of the qubit with the following equation:
The magnitudes of the coefficients and
