Stepanov chose the name; that much we know. Some ruminations, accuracy
unknown. I can't find
any material on it in the newer TC++PL edition I have:

QVector is certainly closer to std::vector than QList is to std::list.
Vector isn't a really good name either,
for people recently taught in elementary school math, or for java
programmers coming in.
For C++ programmers, it gives a much better suggestion of what it is
than calling it QList does.
