Observation of Young's Double-Slit Interference with the Three-Photon N00N State
Yong-Su Kim, Osung Kwon, Sang Min Lee +4
Spatial interference of quantum mechanical particles exhibits a fundamental feature of quantum mechanics. A two-mode entangled state of N particles known as N00N state can give ris…
Four-Photon (In)Distinguishability Transition
Malte C. Tichy, Hyang-Tag Lim, Young-Sik Ra +3
We demonstrate the conspiration of many-particle interferences of different degree to determine the transmission of four photons of tunable indistinguishability through a four-port…
Experimental Implementation of the Universal Transpose Operation
Hyang-Tag Lim, Young-Sik Ra, Yong-Su Kim +2
The universal transpose of quantum states is an anti-unitary transformation that is not allowed in quantum theory. In this work, we investigate approximating the universal transpos…
Atomic vapor quantum memory for a photonic polarization qubit
Young-Wook Cho, Yoon-Ho Kim
We report an experimental realization of an atomic vapor quantum memory for the photonic po- larization qubit. The performance of the quantum memory for the polarization qubit, rea…
Effects of depolarizing quantum channels on BB84 and SARG04 quantum cryptography protocols
Youn-Chang Jeong, Yong-Su Kim, Yoon-Ho Kim
We report experimental studies on the effect of the depolarizing quantum channel on weak-pulse BB84 and SARG04 quantum cryptography. The experimental results show that, in real wor…
Experimental verification of the commutation relation for Pauli spin operators using single-photon quantum interference
Yong-Su Kim, Hyang-Tag Lim, Young-Sik Ra +1
We report experimental verification of the commutation relation for Pauli spin operators using quantum interference of the single-photon polarization state. By superposing the quan…
