Review of Fruit Tree Image Segmentation
Il-Seok Oh
Fruit tree image segmentation is an essential problem in automating a variety of agricultural tasks such as phenotyping, harvesting, spraying, and pruning. Many research papers hav…
Lorentz-Covariant Spin Operator for Spin 1/2 Massive Fields As a Physical Observable
Taeseung Choi, Yeong Deok Han
We derive a relativistic-covariant spin operator for massive case directly from space-time symmetry in Minkowski space-time and investigate the physical properties of a derived spi…
Classical understanding of the electron vortex beams in a uniform magnetic field
Yeong Deok Han, Taeseung Choi
Recently interesting observations on electron vortex beams, which have angular momentum about the center of the vortex beams, have been made. We have shown that the basic features…
Quantum Probability assignment limited by relativistic causality
Yeong Deok Han, Taeseung Choi
The quantum nonlocality is limited by relativistic causality, however, the reason is not fully understood yet. The relativistic causality condition on nonlocal correlations has bee…
Quantum State Discrimination with General Figures of Merit
Won-Young Hwang, Yeong-Deok Han
We solve the problem of quantum state discrimination with "general (symmetric) figures of merit" for an even number of symmetric quantum bits with use of the no-signaling principle…
No-signaling Principle Can Determine Optimal Quantum State Discrimination
Joonwoo Bae, Won-Young Hwang, Yeong-Deok Han
We provide a general framework of utilizing the no-signaling principle in derivation of the guessing probability in the minimum-error quantum state discrimination. We show that, re…
Optimal Quantum State Estimation with Use of the No-Signaling Principle
Yeong-Deok Han, Joonwoo Bae, Xiang-Bin Wang +1
A simple derivation of the optimal state estimation of a quantum bit was obtained by using the no-signaling principle. In particular, the no-signaling principle determines a unique…
Composite Operators and Topological Contributions in Gauge Theory
Jungjai Lee, Yeong Deok Han
In -dimensional gauge theory with a kinetic term based on the p-form tensor gauge field, we introduce a gauge invariant operator associated with the composite formed from a elec…
Entangled Quantum Clocks for Measuring Proper-Time Difference
W. Y. Hwang, D. Ahn, S. W. Hwang +1
We report that entangled pairs of quantum clocks (non-degenerate quantum bits) can be used as a specialized detector for precisely measuring difference of proper-times that each co…
Quantum Coin Tossing
Won Young Hwang, In Gyu Koh, Yeong Deok Han
We show that a secure quantum protocol for coin tossing exist. The existence of quantum coin tossing support the conjecture of D.Mayers [Phys.Rev.Lett. 78, 3414(1997)] that only as…
The quantum cryptography and the unambiguous measurement of quantum nonorthogonal states
Won Young Hwang, In Gyu Koh, Yeong Deok Han
We discuss the unambiguous measurement of quantum nonorthogonal states in connection with the quantum cryptography. We show that checking a ratio of null one to signal is essential…
Quantum Cryptography without Public Announcement of Bases
Won Young Hwang, In Gyu Koh, Yeong Deok Han
This paper provides a simple variation of the basic ideas of the BB84 quantum cryptographic scheme leading to a method of key expansion. A secure random sequence (the bases sequenc…
A note on the supplementary variables in spin-measuring equipments in the EPR-Bell experiment
Won Young Hwang, In Gyu Koh, Yeong Deok Han
We discuss supplementary (or hidden) variables in spin-measuring equipments in EPR-Bell experiment. This theme was considered in a Bell's later work. We generalize it. First, we sh…
