Modular commutator in gapped quantum many-body systems
Isaac H. Kim, Bowen Shi, Kohtaro Kato +1
In arXiv:2110.06932, we argued that the chiral central charge -- a topologically protected quantity characterizing the edge theory of a gapped (2+1)-dimensional system -- can be ex…
Chiral central charge from a single bulk wave function
Isaac H. Kim, Bowen Shi, Kohtaro Kato +1
A -dimensional gapped quantum many-body system can have a topologically protected energy current at its edge. The magnitude of this current is determined entirely by the tem…
Entropy scaling law and the quantum marginal problem: simplification and generalization
Isaac H. Kim
Recently, we introduced a solution to the quantum marginal problem relevant to two-dimensional quantum many-body systems [I. H. Kim, Phys. Rev. X, 11, 021039]. One of the condition…
Low-overhead fault-tolerant quantum computing using long-range connectivity
Lawrence Z. Cohen, Isaac H. Kim, Stephen D. Bartlett +1
Vast numbers of qubits will be needed for large-scale quantum computing due to the overheads associated with error correction. We present a scheme for low-overhead fault-tolerant q…
Fault-tolerant resource estimate for quantum chemical simulations: Case study on Li-ion battery electrolyte molecules
Isaac H. Kim, Eunseok Lee, Ye-Hua Liu +3
We estimate the resources required in the fusion-based quantum computing scheme to simulate electrolyte molecules in Li-ion batteries on a fault-tolerant, photonic quantum computer…
Interleaving: Modular architectures for fault-tolerant photonic quantum computing
Hector Bombin, Isaac H. Kim, Daniel Litinski +5
Useful fault-tolerant quantum computers require very large numbers of physical qubits. Quantum computers are often designed as arrays of static qubits executing gates and measureme…
