Optimal measurements to access classical correlations of two-qubit states
Optimal measurements classical correlations two-qubit states
2010/10/19
We analyze the optimal measurements accessing classical correlations in arbitrary two-qubit states.Two-qubit states can be transformed into the canonical forms via local unitary operations. For the ca...
We present measurements of the charmonium state $h_c(^1P_1)$ made with 106M $\psi'$ events collected by BESIII at BEPCII. Clear signals are observed for $\psi'\to\pi^0 h_c$ with and without the subseq...
