Entanglement area law in interacting bosons from the Bose-Hubbard model to 4 theory and beyond
Donghoon Kim, Tomotaka Kuwahara
The entanglement area law is a universal principle that characterizes quantum many-body phases and underpins tensor network algorithms. Traditionally, its validity has been limited…
Quantum complexity and generalized area law in fully connected models
Donghoon Kim, Tomotaka Kuwahara
The area law for entanglement entropy captures a fundamental constraint on the complexity of quantum many-body ground states and enables their efficient description. While the area…
Provably Efficient Simulation of 1D Long-Range Interacting Systems at Any Temperature
Rakesh Achutha, Donghoon Kim, Yusuke Kimura +1
We introduce a method that ensures efficient computation of one-dimensional quantum systems with long-range interactions across all temperatures. Our algorithm operates within a qu…
Thermal Area Law in Long-Range Interacting Systems
Donghoon Kim, Tomotaka Kuwahara, Keiji Saito
The area law of the bipartite information measure characterizes one of the most fundamental aspects of quantum many-body physics. In thermal equilibrium, the area law for the mutua…
