Quantum teleportation with coherent error in Bell-state measurement
Jeonghyeon Shin, Jaehak Lee, Soojoon Lee +1
Quantum teleportation is a fundamental protocol in quantum information science, whose performance is conventionally evaluated under the assumption of ideal Bell-state measurements.…

Entanglement recovery by reversing the effect of noise in quantum repeater
Sewon Jeong, Shrobona Bagchi, Jaehak Lee +4
We propose a method to directly recover the degree of entanglement distributed by entanglement swapping in the presence of noise. Our approach introduces a reversing operation that…

Photonic Hybrid Quantum Computing
Jaehak Lee, Srikrishna Omkar, Yong Siah Teo +4
Photons are a ubiquitous carrier of quantum information: they are fast, suffer minimal decoherence, and do not require huge cryogenic facilities. Nevertheless, their intrinsically…
