Exponential separation in quantum query complexity of the quantum switch with respect to simulations with standard quantum circuits
Hlér Kristjánsson, Tatsuki Odake, Satoshi Yoshida +4
Quantum theory is consistent with a computational model permitting black-box operations to be applied in an indefinite causal order, going beyond the standard circuit model of comp…
Simulating the quantum switch with quantum circuits is computationally hard
Jessica Bavaresco, Hlér Kristjánsson, Mio Murao +4
Higher-order transformations acting on input quantum channels in an indefinite causal order, such as the quantum switch, cannot be described by quantum circuits using the same numb…
Multicopy quantum state teleportation with application to storage and retrieval of quantum programs
Frédéric Grosshans, Michał Horodecki, Mio Murao +4
This work considers a teleportation task for Alice and Bob in a scenario where Bob cannot perform corrections. In particular, we analyse the task of \textit{multicopy state telepor…
One-to-One Correspondence between Deterministic Port-Based Teleportation and Unitary Estimation
Satoshi Yoshida, Yuki Koizumi, Michał Studziński +2
Port-based teleportation is a variant of quantum teleportation, where the receiver can choose one of the ports in his part of the entangled state shared with the sender, but cannot…
Analytical Lower Bound on Query Complexity for Transformations of Unknown Unitary Operations
Tatsuki Odake, Satoshi Yoshida, Mio Murao
Recent developments have revealed deterministic and exact protocols for performing complex conjugation, inversion, and transposition of a general -dimensional unknown unitary op…
Universal adjointation of isometry operations using conversion of quantum supermaps
Satoshi Yoshida, Akihito Soeda, Mio Murao
Identification of possible transformations of quantum objects including quantum states and quantum operations is indispensable in developing quantum algorithms. Universal transform…
