英文摘要	We present a scheme for a projective measurement of the parity operator P-z =Pi(i=1)(N) sigma(z)((i)) of N qubits. Our protocol uses a single ancillary qubit, or a probe qubit, and involves manipulations of the total spin of the N qubits without requiring individual addressing. We illustrate our protocol in terms of an experimental implementation with atomic ions in a two-zone linear Paul trap, and further discuss its extensions to several more general cases.
