The most discriminable quantum states in the multicopy regime
Maria Kvashchuk, Polina Chernyshova, Lucas E. A. Porto +3
This work investigates which sets of quantum states give rise to the highest achievable success probability in minimum-error state discrimination if multiple copies of the unknown…
Higher-Order Quantum Operations
Philip Taranto, Simon Milz, Mio Murao +2
An operational description of quantum phenomena concerns developing models that describe experimentally observed behaviour. $\textit{Higher-order quantum operations}\unicode{x2014}…
Experimental quantum randomness enhanced by a quantum network
Emanuele Polino, Luis Villegas-Aguilar, Davide Poderini +10
The certification of randomness is essential for both fundamental science and information technologies. Unlike traditional random number generators, randomness obtained from nonloc…
Characterising memory in quantum channel discrimination via constrained separability problems
Ties-A. Ohst, Shijun Zhang, Hai Chau Nguyen +2
Quantum memories are a crucial precondition in many protocols for processing quantum information. A fundamental problem that illustrates this statement is given by the task of chan…
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…
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…
Certifying measurement incompatibility in prepare-and-measure and Bell scenarios
Sophie Egelhaaf, Jef Pauwels, Marco Túlio Quintino +1
We consider the problem of certifying measurement incompatibility in a prepare-and-measure (PM) scenario. We present different families of sets of qubit measurements which are inco…
All incompatible measurements on qubits lead to multiparticle Bell nonlocality
Martin Plávala, Otfried Gühne, Marco Túlio Quintino
Bell nonlocality is a fundamental phenomenon of quantum physics as well as an essential resource for various tasks in quantum information processing. It is known that for the obser…
The quantum switch is uniquely defined by its action on unitary operations
Qingxiuxiong Dong, Marco Túlio Quintino, Akihito Soeda +1
The quantum switch is a quantum process that creates a coherent control between different unitary operations, which is often described as a quantum process which transforms a pair…
