Procedure for Direct Measurement of General Quantum States Using Weak Measurement
Procedure for Direct Measurement of General Quantum States Using Weak Measurement
Recent work [J.S. Lundeen et al. Nature, 474, 188 (2011)] directly measured the wavefunction by weakly measuring a variable followed by a normal (i.e. `strong') measurement of the complementary variable. We generalize this method to mixed states by considering the weak measurement of various products of these observables, thereby providing …
