  We propose a method for entangling two non-interacting qubits by measuring
their parity indirectly through an intermediate mesoscopic system. The protocol
is designed to require only global control and course-grained collective
measurement of the mesoscopic system along with local interactions between the
target qubits and mesoscopic system. A generalization of the method measures
the hamming weight of the qubits' state and probabilistically produces an
entangled state by post-selecting on hamming weight one. Our technique provides
a new design element that can be integrated into quantum processor
architectures and quantum measurement devices.
