Conventions used
There are a number of text conventions used throughout this book.
Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In the second line, the coerce keyword forces the secret string to be a classical unsigned integer on four qubits."
A block of code is set as follows:
def scal[n:!ℕ](const x:uint[n], const y:uint[n])qfree:uint[n] {
count := 0:uint[n];
for k in [0..n) {
count += x[k] && y[k];
}
return count;
}
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
def scal[n:!ℕ](const x:uint[n], const y:uint[n])qfree:uint[n] {
count := 0:uint[n];
for k in [0..n) {
count += x[k] && y[k];
}
return count;
}
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In the world of quantum computing we use the term qubit or quantum bit to represent the bits."
