Fig. 6: Experimental realization of the JEP scheme.
From: Fast joint parity measurement via collective interactions induced by stimulated emission
a The experimental population results in the 2-qubit JEP scheme with initial states \(\left\vert {Q}_{2}{Q}_{0}{Q}_{4}\right\rangle\) prepared to be \(\left\vert 001\right\rangle\) (upper left), \(\left\vert 011\right\rangle\) (upper right), \(\left\vert 100\right\rangle\) (bottom left) and \(\left\vert 110\right\rangle\) (bottom right). At a specific gate time (86 ns), the distant Bell state is generated. b QST measurement of the distant Bell state of Q2 and Q4 at the gate time with Q0 initialized to be in the ground state.
