Catalysis in quantum information theory

P Lipka-Bartosik, H Wilming, NHY Ng - Reviews of Modern Physics, 2024 - APS
Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

Benchmarking one-shot distillation in general quantum resource theories

B Regula, K Bu, R Takagi, ZW Liu - Physical Review A, 2020 - APS

quantitative description of the maximal fidelity achievable in this task, and revealing …

Correlation in catalysts enables arbitrary manipulation of quantum coherence

R Takagi, N Shiraishi - Physical Review Letters, 2022 - APS
Quantum resource manipulation may include an ancillary state called a catalyst, which aids
the transformation while restoring its original form at the end, and characterizing the …

Application of the resource theory of channels to communication scenarios

R Takagi, K Wang, M Hayashi - Physical Review Letters, 2020 - APS
We introduce a resource theory of channels relevant to communication via quantum

Wigner-Araki-Yanase theorem for continuous and unbounded conserved observables

Y Kuramochi, H Tajima - Physical review letters, 2023 - APS
The Wigner-Araki-Yanase (WAY) theorem states that additive conservation laws imply the
commutativity of exactly implementable projective measurements and the conserved …

Universal fault-tolerant quantum computing with stabilizer codes

P Webster, M Vasmer, TR Scruby, SD Bartlett - Physical Review Research, 2022 - APS
The quantum logic gates used in the design of a quantum computer should be both
universal, meaning arbitrary quantum computations can be performed, and fault-tolerant …

Universal limitation of quantum information recovery: symmetry versus coherence

H Tajima, K Saito - arxiv preprint arxiv:2103.01876, 2021 - arxiv.org
Quantum information is scrambled via chaotic time evolution in many-body systems. The
recovery of initial information embedded locally in the system from the scrambled quantum …
