Efficient direct quantum state tomography using fan-out couplings
Jaekwon Chang, Guedong Park, Hyunseok Jeong +2
Characterizing quantum states is essential for validating quantum devices, yet conventional quantum state tomography becomes prohibitively expensive as system size grows. Direct to…
Robust and bright polarization-entangled photon sources exploiting non-critical phase matching without periodic poling
Ilhwan Kim, Yosep Kim, Yong-Su Kim +2
Entangled photon sources are essential for quantum information applications, including quantum computation, quantum communication, and quantum metrology. Periodically poled (PP) cr…
Entanglement swapping via lossy channels using photon-number-encoded states
Wan Zo, Bohdan Bilash, Donghwa Lee +5
Entanglement shared between distant parties is a key resource in quantum networks. However, photon losses in quantum channels significantly reduce the success probability of entang…
Photonic variational quantum eigensolver using entanglement measurements
Jinil Lee, Wooyeong Song, Donghwa Lee +6
Variational quantum eigensolver (VQE), which combines quantum systems with classical computational power, has been arisen as a promising candidate for near-term quantum computing a…
Nondestructive discrimination of Bell states between distant parties
Bohdan Bilash, Youngrong Lim, Hyukjoon Kwon +4
Identifying Bell states without destroying it is frequently dealt with in nowadays quantum technologies such as quantum communication and quantum computing. In practice, quantum en…
Experimental linear optical computing of the matrix permanent
Yosep Kim, Kang-Hee Hong, Joonsuk Huh +1
Linear optical computing (LOC) with thermal light has recently gained attention because the problem is connected to the permanent of a Hermitian positive semidefinite matrix (HPSM)…
