Resource Theory of Aquaternionicity: Every Pure State Is a Replicable Resource for Exact Simulation of Arbitrary Quantum Operations
Hayato Arai, Yasuaki Nakayama
An alchemical resource theory admits a nonfree state that can be exactly replicated by free operations and whose finitely many copies enable exact simulation of arbitrary quantum i…
Universal distillation of quantum entanglement
Ryuji Takagi, Kaito Watanabe, Takaya Matsuura +2
Distillable entanglement---the maximum rate of Bell states extractable from the given noisy entangled states via local operations and classical communication (LOCC)---has been a ce…
Inverse Problem of Alchemical Resource Theory: Replication and Universal Simulation Single Out Imaginarity and Parity Asymmetry
Yasuaki Nakayama, Hayato Arai
Quantum resource theories usually begin with a prescribed free structure and ask what tasks become possible when a resource is supplied. We study the inverse problem of alchemical…
Entanglement Generation Beyond Quantum Theory: From Product States to Popescu-Rohrlich Boxes
Shun Umekawa, Akihiro Hokkyo, Hayato Arai +1
Entanglement generation is a fundamental dynamical capability in quantum information science and underpins many quantum advantages. While quantum theory enables it through unitary…
Intersubjectivity as a principle determining physical observables and non-classicality
Shun Umekawa, Koki Ono, Hayato Arai
We identify an operational principle that singles out Projection-Valued Measures (PVMs) among general Positive Operator-Valued Measures (POVMs), bridging the modern quantum measure…
