Frequency multiplexed entanglement for continuous-variable quantum key distribution
Olena Kovalenko, Young-Sik Ra, Yin Cai +4
Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room temperature. Together with…
Robust squeezed light against mode mismatch using a self imaging optical parametric oscillator
Chan Roh, Geunhee Gwak, Young-Sik Ra
We present squeezed light that is robust against spatial mode mismatch (beam displacement, tilt, and beam-size difference), which is generated from a self-imaging optical parametri…
Mode-Dependent Loss Model for Multimode Photon-Subtracted States
Mattia Walschaers, Young-Sik Ra, Nicolas Treps
Multimode photon-subtraction provides an experimentally feasible option to construct large non-Gaussian quantum states in continuous-variable quantum optics. The non-Gaussian featu…
Non-Gaussian quantum states of a multimode light field
Young-Sik Ra, Adrien Dufour, Mattia Walschaers +4
Even though Gaussian quantum states of multimode light are promising quantum resources due to their scalability, non-Gaussianity is indispensable for quantum technologies, in parti…
Gate Fidelities, Quantum Broadcasting, and Assessing Experimental Realization
Hyang-Tag Lim, Young-Sik Ra, Yong-Su Kim +2
We relate gate fidelities of experimentally realized quantum operations to the broadcasting property of their ideal operations, and show that the more parties a given quantum opera…
