Efficient Graph State Generation in Linear Optics
Seungbeom Chin, William John Munro
Graph states are central resources for quantum information processing, supporting applications in computation, communication, and error correction. In photonic systems, they are ty…
Shortcut to Multipartite Entanglement Generation: A Graph Approach to Boson Subtractions
Seungbeom Chin, Yong-Su Kim, Marcin Karczewski
We propose a graph method for systematically searching for schemes that can generate multipartite entanglement in linear bosonic systems with heralding. While heralded entanglement…
Quantum circuit simulation of linear optics using fermion to qubit encoding
Seungbeom Chin, Jaehee Kim, Joonsuk Huh
This work proposes a digital quantum simulation protocol for the linear scattering process of bosons, which provides a simple extension to partially distinguishable boson cases. Ou…
Entangling three identical particles via spatial overlap
Donghwa Lee, Tanumoy Pramanik, Young-Wook Cho +3
Quantum correlations between identical particles are at the heart of quantum technologies. Several studies with two identical particles have shown that the spatial overlap and indi…
Graph Picture of Linear Quantum Networks and Entanglement
Seungbeom Chin, Yong-Su Kim, Sangmin Lee
The indistinguishability of quantum particles is widely used as a resource for the generation of entanglement. Linear quantum networks (LQNs), in which identical particles linearly…
Taming identical particles for discerning the genuine non-locality
Seungbeom Chin, Jung-Hoon Chun
This work provides a comprehensive approach to analyze the entanglement between subsystems generated by identical particles, based on the symmetric/exterior algebra (SEA) and micro…
Entangling Bosons through Particle Indistinguishability and Spatial Overlap
Mariana R. Barros, Seungbeom Chin, Tanumoy Pramanik +4
Particle identity and entanglement are two fundamental quantum properties that work as major resources for various quantum information tasks. However, it is still a challenging pro…
Reduced density matrix of nonlocal identical particles
Seungbeom Chin, Joonsuk Huh
We probe the theoretical connection among three different approaches to analyze the entanglement of identical particles, i.e., the first quantization language (1QL), elementary-sym…
Entanglement of Identical Particles and Coherence in the First Quantization Language
Seungbeom Chin, Joonsuk Huh
We suggest a formalism to illustrate the entanglement of identical particles in the first quantization language (1QL). Our 1QL formalism enables one to exploit all the well-establi…
Partial Distinguishability as a Coherence Resource in Boson Sampling
Seungbeom Chin, Joonsuk Huh
Quantum coherence is a useful resource that is consumed to accomplish several tasks that classical devices are hard to fulfill. Especially, it is considered to be the origin of qua…
Quantum Computing for Molecular Vibronic Spectra and Gaussian Boson Sampling
Seungbeom Chin, Joonsuk Huh
Boson sampling (BS) is a multimode linear optical problem that is expected to be intractable on classical computers. It was recently suggested that molecular vibronic spectroscopy…
Majorization and the time complexity of linear optical networks
Seungbeom Chin, Joonsuk Huh
This work shows that the majorization of photon distributions is related to the runtime of classically simulating multimode passive linear optics, which explains one aspect of the…
Generalized Coherence Concurrence and Path distinguishability
Seungbeom Chin
We propose a new family of coherence monotones, named the \emph{generalized coherence concurrence} (or coherence -concurrence), which is an analogous concept to the generalized…
Coherence number as a discrete quantum resource
Seungbeom Chin
We introduce a new discrete coherence monotone named the \emph{coherence number}, which is a generalization of the coherence rank to mixed states. After defining the coherence numb…
Generalized concurrence in boson sampling
Seungbeom Chin, Joonsuk Huh
A fundamental question in linear optical quantum computing is to understand the origin of the quantum supremacy in the physical system. It is found that the multimode linear optica…
Momentum bispinor, two-qubit entanglement and twistor space
Seungbeom Chin, Sangmin Lee
We re-examine the symmetry structure of massive momentum bispinors in four dimensional Minkowski spacetime and apply the result to the geometry of a two-qubit entanglement system.…
