Phase-Sensitive Crystal-Edge Effects in Linear Optical Parametric Oscillators: Why Nominally Identical Squeezers Behave Differently
Jonas Junker, Donghwa Lee, Reda Louahaj +5
Efficient and reproducible squeezed-light sources are essential for quantum information processing and precision metrology. Compact linear standing-wave optical parametric oscillat…
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…
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…
Reference-Frame-Independent, Measurement-Device-Independent quantum key distribution using fewer quantum states
Donghwa Lee, Seong-Jin Hong, Young-Wook Cho +6
Reference-Frame-Independent Quantum Key Distribution (RFI-QKD) provides a practical way to generate secret keys between two remote parties without sharing common reference frames.…
