Contextuality and Informational Redundancy
Ehtibar N. Dzhafarov, Janne V. Kujala
A noncontextual system of random variables may become contextual if one adds to it a set of new variables, even if each of them is obtained by the same context-wise function of the…
Retrievability of information in quantum and realistic hidden variable theories
Roope Uola, Erkka Haapasalo, Juha-Pekka Pellonpää +1
We propose a generalisation of the Leggett-Garg conditions for macrorealistic behaviour. Our proposal relies on relaxing the postulate of non-invasive measurability with that of re…
Non-Markovianity-based ultrasensitive parameter estimation
Olli Siltanen
Accurate parameter estimation is a central task in quantum metrology and sensing, where quantum resources can provide precision beyond classical limits. In realistic settings, howe…
Overcoming noise in quantum teleportation with multipartite hybrid entanglement
Zhao-Di Liu, Olli Siltanen, Tom Kuusela +5
Quantum entanglement and decoherence are the two counterforces of many quantum technologies and protocols. For example, while quantum teleportation is fueled by a pair of maximally…
Repeated measurements on non-replicable systems and their consequences for Unruh-DeWitt detectors
Nicola Pranzini, Guillermo García-Pérez, Esko Keski-Vakkuri +1
The Born rule describes the probability of obtaining an outcome when measuring an observable of a quantum system. As it can only be tested by measuring many copies of the system un…
Anticipative measurements in hybrid quantum-classical computation
Teiko Heinosaari, Daniel Reitzner, Alessandro Toigo
Before the availability of large scale fault-tolerant quantum devices, one has to find ways to make the most of current noisy intermediate-scale quantum devices. One possibility is…
Naimark dilations of qubit POVMs and joint measurements
Juha-Pekka Pellonpää, Sébastien Designolle, Roope Uola
Measurement incompatibility is one of the cornerstones of quantum theory. This phenomenon appears in many forms, of which the concept of non-joint measurability has received consid…
Link prediction with continuous-time classical and quantum walks
Mark Goldsmith, Guillermo García-Pérez, Joonas Malmi +3
Protein-protein interaction (PPI) networks consist of the physical and/or functional interactions between the proteins of an organism. Since the biophysical and high-throughput met…
Dispensing of quantum information beyond no-broadcasting theorem -- is it possible to broadcast anything genuinely quantum?
Teiko Heinosaari, Anna Jenčová, Martin Plávala
No-broadcasting theorem is one of the most fundamental results in quantum information theory; it guarantees that the simplest attacks on any quantum protocol, based on eavesdroppin…
An attempt to understand relational quantum mechanics
Pekka Lahti, Juha-Pekka Pellonpää
We search for a possible mathematical formulation of some of the key ideas of the relational interpretation of quantum mechanics and study their consequences. We also briefly overv…
Quantum transport efficiency in noisy random-removal and small-world networks
Arzu Kurt, Matteo A. C. Rossi, Jyrki Piilo
We report the results of an in-depth study of the role of graph topology on quantum transport efficiency in random removal and Watts-Strogatz networks. By using four different envi…
Spatial search by continuous-time quantum walks on renormalized Internet networks
Joonas Malmi, Matteo A. C. Rossi, Guillermo García-Pérez +1
We study spatial search with continuous-time quantum walks on real-world complex networks. We use smaller replicas of the Internet network obtained with a recent geometric renormal…
Non-Markovian Quantum State Diffusion for Spin Environments
Valentin Link, Kimmo Luoma, Walter T. Strunz
We introduce an exact open system method to describe the dynamics of quantum systems that are strongly coupled to specific types of environments comprising of spins, such as centra…
Partial ignorance communication tasks in quantum theory
Oskari Kerppo
We introduce a generalization of communication of partial ignorance where both parties of a prepare-and-measure setup receive inputs from a third party before a success metric is m…
Order preserving maps on quantum measurements
Teiko Heinosaari, Maria Anastasia Jivulescu, Ion Nechita
We study the partially ordered set of equivalence classes of quantum measurements endowed with the post-processing partial order. The post-processing order is fundamental as it ena…
Quantum simulation of dissipative collective effects on noisy quantum computers
Marco Cattaneo, Matteo A. C. Rossi, Guillermo García-Pérez +2
Dissipative collective effects are ubiquitous in quantum physics, and their relevance ranges from the study of entanglement in biological systems to noise mitigation in quantum com…
