Scalability and performance metrics for boson sampling devices
Dong-Gil Im, Chung-Hyun Lee, Joonsuk Huh +1
Linear-optical platforms provide a promising route to demonstrate quantum computational advantage, particularly through the boson sampling problem. While a boson sampling system sh…
Two-Photon Induced Coherence without Induced Emission
Dong-Gil Im, Seung-Yeun Yoo, Chung-Hyun Lee +2
At the heart of recent breakthroughs in quantum imaging and spectroscopy utilizing undetected photons lies the quantum optical effect known as induced coherence without induced emi…
Quantum teleportation is a reversal of quantum measurement
Seung-Woo Lee, Dong-Gil Im, Yoon-Ho Kim +2
We introduce a generalized concept of quantum teleportation in the framework of quantum measurement and reversing operation. Our framework makes it possible to find an optimal prot…
Dispersion cancellation in a quantum interferometer with independent single photons
Dong-Gil Im, Yosep Kim, Yoon-Ho Kim
A key technique to perform a proper quantum information processing is to get a high visibility quantum interference between independent single photons. One of the crucial elements…
Universal compressive characterization of quantum dynamics
Yosep Kim, Yong Siah Teo, Daekun Ahn +6
Recent quantum technologies utilize complex multidimensional processes that govern the dynamics of quantum systems. We develop an adaptive diagonal-element-probing compression tech…
Observing the "quantum Cheshire cat" effect with noninvasive weak measurement
Yosep Kim, Dong-Gil Im, Yong-Su Kim +4
One of the common conceptions of nature, typically derived from the experiences with classical systems, is that attributes of the matter coexist with the substance. In the quantum…
Stark Tuning of Single-Photon Emitters in Hexagonal Boron Nitride
Gichang Noh, Daebok Choi, Jin-Hun Kim +4
Single-photon emitters play an essential role in quantum technologies, including quantum computing and quantum communications. Atomic defects in hexagonal boron nitride (h-BN) have…
