As usual, it is useful to think about how a bilinear form looks like in terms of vectors and matrices.
Unlike a linear form, which was a vector, because it has two inputs, the bilinear form is represented by a matrix which encodes the value for each possible pair of basis vectors.
In terms of that matrix, the form is then given by:
It's great right? You can't link to your other answer alone: Stack Overflow link-only answer policy, but you can't copy the other answer either.
And because not all duplicate close votes succeed, see e.g. stackoverflow.com/questions/59649238/how-to-use-the-m5ops-in-gem5-such-m5-exit-and-m5-dump-stats-in-se-mode/63955139#63955139 the result is that someone else will come and answer the same thing in a different wording.
And some answers answer two questions that are not duplicates, e.g. superset/subset questions.
So just do a slight variation wording yourself and get all the reputation.

Is Jobs evil? Is he interesting? Undoubtedly.

Unlike abugida, these actually make you guess vowels, which are mostly or all not written down in any way. Terrible.
E.g.: the main Arabic script.
Controlled quantum gates are gates that have two types of input qubits:
These gates can be understood as doing a certain unitary operation only if the control qubits are enabled or disabled.
The first example to look at is the CNOT gate.
Figure 1. . Source.
The black dot means "control qubit", and "U" means an arbitrary Unitary operation.
When the operand has a conventional symbol, e.g. the Figure "Quantum NOT gate symbol" for the quantum NOT gate to form the CNOT gate, that symbol is used in the operand instead.
