Gate Fidelities, Quantum Broadcasting, and Assessing Experimental Realization
Hyang-Tag Lim, Young-Sik Ra, Yong-Su Kim +2
We relate gate fidelities of experimentally realized quantum operations to the broadcasting property of their ideal operations, and show that the more parties a given quantum opera…
Ultra-low noise single-photon detector based on Si avalanche photodiode
Yong-Su Kim, Youn-Chang Jeong, Sebastien Sauge +2
We report operation and characterization of a lab-assembled single-photon detector based on commercial silicon avalanche photodiodes (PerkinElmer C30902SH, C30921SH). Dark count ra…
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…
