Preparing quantum many-body scar states on quantum computers
Erik J. Gustafson, Andy C. Y. Li, Abid Khan +6
Quantum many-body scar states are highly excited eigenstates of many-body systems that exhibit atypical entanglement and correlation properties relative to typical eigenstates at t…
Quantum Chaos and Circuit Parameter Optimization
Joonho Kim, Yaron Oz, Dario Rosa
We explore quantum chaos diagnostics of variational circuit states at random parameters and study their correlation with the circuit expressibility and the optimization of control…
Quantum Energy Landscape and VQA Optimization
Joonho Kim, Yaron Oz
We study the effects of entanglement and control parameters on the energy landscape and optimization performance of the variational quantum circuit. Through a systematic analysis o…
The Relativistic Spherical Top as a Massive Twistor
Joon-Hwi Kim, Jung-Wook Kim, Sangmin Lee
We prove the equivalence between two traditional approaches to the classical mechanics of a massive spinning particle in special relativity. One is the spherical top model of Hanso…
AdS black holes and finite N indices
Prarit Agarwal, Sunjin Choi, Joonho Kim +2
We study the index of 4d Yang-Mills theory with gauge group, focussing on the physics of the dual BPS black holes in . Certain aspects of th…
Instantons from Blow-up
Joonho Kim, Sung-Soo Kim, Ki-Hong Lee +2
We generalize Nakajima-Yoshioka blowup equations to arbitrary gauge group with hypermultiplets in arbitrary representations. Using our blowup equations, we compute the instanton pa…
