Error-mitigated photonic variational quantum eigensolver using a single-photon ququart
Donghwa Lee, Jinil Lee, Seongjin Hong +6
We report the experimental resource-efficient implementation of the variational quantum eigensolver (VQE) using four-dimensional photonic quantum states of single-photons. The four…
Implementation of a 3 x 3 directionally-unbiased linear optical multiport
Ilhwan Kim, Donghwa Lee, Seongjin Hong +4
Linear optical multiports are widely used in photonic quantum information processing. Naturally, these devices are directionally-biased since photons always propagate from the inpu…
Efficient linear optical generation of a multipartite W state
Pawel Blasiak, Ewa Borsuk, Marcin Markiewicz +1
A novel scheme is presented for generation of a multipartite W state for arbitrary number of qubits. Based on a recent proposal of entanglement without touching, it serves to demon…
Characterizing Bell state analyzer using weak coherent pulses
Donghwa Lee, Young-Wook Cho, Hyang-Tag Lim Sang-Wook Han +3
Bell state analyzer (BSA) is one of the most crucial apparatus in photonic quantum information processing. While linear optics provide a practical way to implement BSA, it provides…
Equitable multiparty quantum communication without a trusted third party
Tanumoy Pramanik, Dong-Hwa Lee, Young-Wook Cho +6
Multiparty quantum communication provides delightful applications including quantum cryptographic communication and quantum secret sharing. Measurement-Device-Independent (MDI) qua…
Experimental implementation of arbitrary entangled operations
Seongjin Hong, Chang Hoon Park, Yeon-Ho Choi +4
Quantum entanglement lies at the heart of quantum mechanics in both fundamental and practical aspects. The entanglement of quantum states has been studied widely, however, the enta…
