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…
