Dynamical resource theory of time-reversal symmetry breaking

Jisho Miyazaki, Kohdai Kuroiwa, Mio Murao

Time-reversal symmetry and its violation (T-violation) are fundamental across diverse physics domains, from particle physics to fluctuation theorems and reciprocity. While time-rev…

Probabilistic Storage and Retrieval of Quantum Superchannels for "Retrospective" Intervention

Wataru Yokojima, Jisho Miyazaki, Mio Murao

Storing an unknown quantum computation in a quantum state and retrieving it at a desired later time is a challenging task, hindered by the no-programming theorem of quantum computa…

Localization of joint quantum measurements on by entangled resources with Schmidt number at most

Seiseki Akibue, Jisho Miyazaki

Localizable measurements are joint quantum measurements that can be implemented using only non-adaptive local operations and shared entanglement. We provide a protocol-independent…

Quantum Advantage in Storage and Retrieval of Isometry Channels

Satoshi Yoshida, Jisho Miyazaki, Mio Murao

Storage and retrieval refer to the task of encoding an unknown quantum channel into a quantum state, known as the program state, such that the channel can later be retrieved. T…

Optimizing Entanglement Manipulation via Algebraic-Geometric Decompositions and Semidefinite Programming Hierarchies

Seiseki Akibue, Jisho Miyazaki, Hiroyuki Osaka

In the study of distributed quantum information processing, it is a fundamental problem to optimize local operations in the implementation of non-local quantum operations assisted…

Non-locality of conjugation symmetry: characterization and examples in quantum network sensing

Jisho Miyazaki, Seiseki Akibue

Some quantum information processing protocols necessitate quantum operations that are invariant under complex conjugation. In this study, we analyze the non-local resources necessa…

Imaginarity-free quantum multiparameter estimation

Jisho Miyazaki, Keiji Matsumoto

Multiparameter quantum estimation is made difficult by the following three obstacles. First, incompatibility among different physical quantities poses a limit on the attainable pre…

Strongly non-quantitative classical information in quantum carriers

Jisho Miyazaki

A simple method to enhance the quality of communication is to send a carrier with its copies. Classical information theory says that information behaves quantitatively under copyin…

Complex conjugation supermap of unitary quantum maps and its universal implementation protocol

Jisho Miyazaki, Akihito Soeda, Mio Murao

A complex conjugation of unitary quantum map is a second-order map (supermap) that maps a unitary operator to its complex conjugate . First, we present a deterministic qua…

Composite systems and state transformations in topos quantum theory

Jisho Miyazaki

Topos quantum theory provides representations of quantum states as direct generalizations of the probability distribution, namely probability valuation. In this article, we conside…

An analysis of the trade-off between spatial and temporal resources for measurement-based quantum computation

Jisho Miyazaki, Michal Hajdušek, Mio Murao

In measurement-based quantum computation (MBQC), elementary quantum operations can be more parallelized than the quantum circuit model by employing a larger Hilbert space of graph…
