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…
