  Common flux qubit readout schemes are qubit dominated, meaning they measure
in the energy eigenbasis of the qubit. For various applications meausrements in
a basis different from the energy eigenbasis are required. Here we present an
indirect measurement protocol, which is detector dominated instead of qubit
dominated, yielding a projective measurements in the persistent current basis
for arbitrary bias points. We show that with our setup it is possible to
perform a quantum nondemolition measurement (QND) in the persistent current
basis at all flux bias points with fidelities reaching almost 100%.
