Topological Quantum Gate Construction by Iterative Pseudogroup Hashing

Michele Burrello, Giuseppe Mussardo, Xin Wan

We describe the hashing technique to obtain a fast approximation of a target quantum gate in the unitary group SU(2) represented by a product of the elements of a universal basis.…

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…

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…
