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 images/_pragprog/svg-17.png qubelets and three inverted triangle images/_pragprog/svg-18.png qubelets, shown here:

Looking at this qubit, we can deduce the following:

  • When measured, the pentagon qubelets have a greater chance of being selected ...
