Multipolar hierarchy of efficient quantum polarization measures
P. de la Hoz, A. B. Klimov. G. Bjork, Y. -H. Kim +4
We advocate a simple multipole expansion of the polarisation density matrix. The resulting multipoles appear as successive moments of the Stokes variables and can be obtained from…
Realizing Physical Approximation of the Partial Transpose
Hyang-Tag Lim, Yong-Su Kim, Young-Sik Ra +2
The partial transpose by which a subsystem's quantum state is solely transposed is of unique importance in quantum information processing from both fundamental and practical point…
Experimental demonstration of decoherence suppression via quantum measurement reversal
Jong-Chan Lee, Youn-Chang Jeong, Yong-Su Kim +1
Taming decoherence is essential in realizing quantum computation and quantum communication. Here we experimentally demonstrate that decoherence due to amplitude damping can be supp…
Reversing the Weak Quantum Measurement for a Photonic Qubit
Yong-Su Kim, Young-Wook Cho, Young-Sik Ra +1
We demonstrate the conditional reversal of a weak (partial-collapse) quantum measurement on a photonic qubit. The weak quantum measurement causes a nonunitary transformation of a q…
