Local Gaussian bounds on the non-destructive discrimination of two-mode squeezed states
Mi-Jung So, James Moran, Youngrong Lim +2
Typical measurement setups in quantum systems are destructive, meaning that states are irretrievably altered after measurement. In this work, we analyse non-destructive discriminat…
Precursors to Topological Phase Transition in Topological Ladders
Seungju Han, Mahn-Soo Choi
We study the coupling of two topologcal subsystems in distinct topological states, and show that it leads to a precursor behavior of the topological phase transition in the overall…
Subgap modes in two-dimensional magnetic Josephson junctions
Yinan Fang, Seungju Han, Stefano Chesi +1
We consider two-dimensional superconductor/ferromagnet/superconductor junctions and investigate the subgap modes along the junction interface. The subgap modes exhibit characterist…
Single-Qubit Reaped Quantum State Tomography
Mahn-Soo Choi
Quantum state tomography is the experimental procedure of determining an unknown state. It is not only essential for the verification of resources and processors of quantum informa…
Probing Kondo spin fluctuations with scanning tunneling microscopy and electron spin resonance
Yinan Fang, Stefano Chesi, Mahn-Soo Choi
We theoretically analyze a state-of-the-art experimental method based on a combination of electron spin resonance and scanning tunneling microscopy (ESR-STM), to directly probe the…
Geometric Manipulation of a Decoherence-Free Subspace in Atomic Ensembles
Dongni Chen, Si Luo, Ying-Dan Wang +2
We consider an ensemble of atoms with -type level structure trapped in a single-mode cavity, and propose a geometric scheme of coherent manipulation of quantum states on the sub…
