Domain walls from SPT-sewing
Yabo Li, Zijian Song, Aleksander Kubica +1
We introduce a systematic method for constructing gapped domain walls of topologically ordered systems by gauging a lower-dimensional symmetry-protected topological (SPT) order. Ba…
Learning State Preparation Circuits for Quantum Phases of Matter
Hyun-Soo Kim, Isaac H. Kim, Daniel Ranard
Many-body ground state preparation is an important subroutine used in the simulation of physical systems. In this paper, we introduce a flexible and efficient framework for obtaini…
Code switching revisited: Low-overhead magic state preparation using color codes
Lucas Daguerre, Isaac H. Kim
We propose a protocol to prepare a high-fidelity magic state on a two-dimensional (2D) color code using a three-dimensional (3D) color code. Our method modifies the known code swit…
On the energy barrier of hypergraph product codes
Guangqi Zhao, Andrew C. Doherty, Isaac H. Kim
A macroscopic energy barrier is a necessary condition for self-correcting quantum memory. In this paper, we prove tight bounds on the energy barrier applicable to any quantum code…
Geometric additivity of modular commutator for multipartite entanglement
Sung-Min Park, Isaac H. Kim, Eun-Gook Moon
A recent surge of research in many-body quantum entanglement has uncovered intriguing properties of quantum many-body systems. A prime example is the modular commutator, which can…
Non-unitary Coupled Cluster Enabled by Mid-circuit Measurements on Quantum Computers
Alexandre Fleury, James Brown, Erika Lloyd +2
Many quantum algorithms rely on a quality initial state for optimal performance. Preparing an initial state for specific applications can considerably reduce the cost of probabilis…
