Measuring statistics-induced entanglement entropy with a Hong-Ou-Mandel interferometer
Gu Zhang, Changki Hong, Tomer Alkalay +4
Despite its ubiquity in quantum computation and quantum information, a universally applicable definition of quantum entanglement remains elusive. The challenge is further accentuat…
Partitioning of Diluted Anyons Reveals their Braiding Statistics
June-Young M. Lee, Changki Hong, Tomer Alkalay +5
Correlations of partitioned particles carry essential information about their quantumness. Partitioning full beams of charged particles leads to current fluctuations, with their au…
Fast raster scan multiplexed charge stability measurements toward high-throughput quantum dot array calibration
Wonjin Jang, Min-Kyun Cho, Myungwon Lee +6
We report raster scan multiplexed charge-stability diagram measurements for tuning multiple gate-defined quantum dots in GaAs/AlGaAs heterostructures. We evaluate the charge sensit…
Attractive Coulomb interactions in a triple quantum dot
Changki Hong, Gwangsu Yoo, Jinhong Park +7
Electron pairing due to a repulsive Coulomb interaction in a triple quantum dot (TQD) is experimentally studied. It is found that electron pairing in two dots of a TQD is mediated…
Nontrivial transition of transmission in a highly open quantum point contact in the quantum Hall regime
Changki Hong, Jinhong Park, Yunchul Chung +2
Transmission through a quantum point contact (QPC) in the quantum Hall regime usually exhibits multiple resonances as a function of gate voltage and high nonlinearity in bias. Such…
Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
M. Seo, C. Hong, S. -Y. Lee +5
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The pri…
