Recycling qubits in near-term quantum computers
Galit Anikeeva, Isaac H. Kim, Patrick Hayden
Quantum computers are capable of efficiently contracting unitary tensor networks, a task that is likely to remain difficult for classical computers. For instance, networks based on…
Fault-tolerant qubit from a constant number of components
Kianna Wan, Soonwon Choi, Isaac H. Kim +2
With gate error rates in multiple technologies now below the threshold required for fault-tolerant quantum computation, the major remaining obstacle to useful quantum computation i…
An exactly solvable ansatz for statistical mechanics models
Isaac H. Kim
We propose a family of "exactly solvable" probability distributions to approximate partition functions of two-dimensional statistical mechanics models. While these distributions li…
Entropy scaling law and the quantum marginal problem
Isaac H. Kim
Quantum many-body states that frequently appear in physics often obey an entropy scaling law, meaning that an entanglement entropy of a subsystem can be expressed as a sum of terms…
Domain wall topological entanglement entropy
Bowen Shi, Isaac H. Kim
We study the ground-state entanglement of gapped domain walls between topologically ordered systems in two spatial dimensions. We derive a universal correction to the ground-state…
Entanglement bootstrap approach for gapped domain walls
Bowen Shi, Isaac H. Kim
We develop a theory of gapped domain wall between topologically ordered systems in two spatial dimensions. We find a new type of superselection sector -- referred to as the parton…
