A Classically Impossible Task Done by Using Quantum Resources

Won-Young Hwang

We propose a task that cannot be done by using any classical mechanical means but can be done with quantum resources. The task is closely related to the violation of Bell's inequal…

-Epistemic Models and Bell Theorem

Won-Young Hwang

We consider a question in what condition a mixed state which can be decomposed in different ways cannot be described by a single set of hidden variables. The condition is closely r…

Reference-Frame-Independent Measurement-Device-Independent Quantum Key Distribution with Uncharacterized Qubits

Won-Young Hwang

We propose a reference-frame-independent measurement-device-independent quantum key distribution with uncharacterized quantum bits. We show the security of the protocol. The protoc…

Improved Measurement-Device-Independent Quantum Key Distribution with Uncharacterized Qubits

Won-Young Hwang, Hong-Yi Su, Joonwoo Bae

We propose an improved bound for the difference between phase and bit error rate in measurement-device-independent quantum key distribution with uncharacterized qubits. We show by…

General tradeoff relations of quantum nonlocality in the Clauser-Horne-Shimony-Holt scenario

Hong-Yi Su, Jing-Ling Chen, Won-Young Hwang

General tradeoff relations present in nonlocal correlations of bipartite systems are studied, regardless of any specific quantum states and measuring directions. Extensions to mult…

Optical Activity and Mirror-Symmetry

Won-Young Hwang

A misconception that non-chiral molecules have no optical activity at all is widespread. However, at molecular level even non-chiral molecules have optical activity. Optical activi…
