Experimental Learning of Pure Quantum States using Sequential Single-Shot Measurement Outcomes
Sang Min Lee, Hee Su Park, Jinhyoung Lee +2
We experimentally implement a machine-learning method for accurately identifying unknown pure quantum states. The method, called single-shot measurement learning, achieves the theo…
Efficient High-dimensional Quantum Key Distribution with Hybrid Encoding
Yonggi Jo, Hee Su Park, Seung-Woo Lee +1
We propose a schematic setup of quantum key distribution (QKD) with an improved secret key rate based on high-dimensional quantum states. Two degrees-of-freedom of a single photon,…
Quantum teleportation of shared quantum secret
Sang Min Lee, Seung-Woo Lee, Hyunseok Jeong +1
Quantum teleportation allows to transfer unknown quantum states between distant parties. It is not only a primitive of quantum communications but also an essential task in realizat…
Experimental demonstration of high-dimensional photonic spatial entanglement between multi-core optical fibers
Hee Jung Lee, Sang-Kyung Choi, Hee Su Park
Fiber transport of multi-dimensional photonic qudits promises high information capacity per photon without space restriction. This work experimentally demonstrates transmission of…
A Time-Multiplexed Heralded Single-Photon Source
Fumihiro Kaneda, Bradley G. Christensen, Jia Jun Wong +3
Photons have proven to be excellent carriers of quantum information, and play essential roles in numerous quantum information processing (QIP) applications. In particular, heralded…
Linear optical scheme for producing polarization-entangled NOON states
Su-Yong Lee, Tomasz Paterek, Hee Su Park +1
We propose a linear optical scheme that can conditionally generate high NOON states using polarization modes. This scheme provides advantages over the previous proposals on path-en…
Experimental Realization of a Four-Photon Seven-Qubit Graph State for One-Way Quantum Computation
Sang Min Lee, Hee Su Park, Jaeyoon Cho +5
We propose and demonstrate the scaling up of photonic graph state through path qubit fusion. Two path qubits from separate two-photon four-qubit states are fused to generate a two-…
Observation of Young's Double-Slit Interference with the Three-Photon N00N State
Yong-Su Kim, Osung Kwon, Sang Min Lee +4
Spatial interference of quantum mechanical particles exhibits a fundamental feature of quantum mechanics. A two-mode entangled state of N particles known as N00N state can give ris…
Heralded Generation of High-Visibility Three-Photon NOON States
Heonoh Kim, Hee Su Park, Sang-Kyung Choi
We describe an experimental demonstration of a novel three-photon NOON state generator using a single source of photons based on spontaneous parametric down-conversion (SPDC). The…
Quantum Lithography Based on Multiple Light Exposures for Arbitrary Sub-Diffraction-Limit Pattern Generation
Hee Su Park, Sun Kyung Lee
We propose a super-resolution quantum lithography scheme based on coherent population trapping in lambda-type atoms coupled to temporally-cascaded standing-wave driving fields. By…
