Efficient reconstruction, benchmarking and validation of cross-talk models in readout noise in near-term quantum devices
Jan Tuziemski, Filip B. Maciejewski, Joanna Majsak +5
Readout errors contribute significantly to the overall noise affecting present-day quantum computers. However, the complete characterization of generic readout noise is infeasible…
The quantum network as an environment
Erik Aurell, Roberto Mulet, Jan Tuziemski
quantum system interacting with other quantum systems experiences these other systems asan effective environment. The environment is the result of integrating out all the other deg…
The Vernon transform and its use in quantum thermodynamics
Erik Aurell, Jan Tuziemski
The thermodynamics of a quantum system interacting with an environment that can be assimilated to a harmonic oscillator bath has been extensively investigated theoretically. In rec…
Decoherence and information encoding in quantum reference frames
Jan Tuziemski
Reference frames are of special importance in physics. They are usually considered to be idealized entities. However, in most situations, e.g. in laboratories, physical processes a…
Out-of-time-ordered correlation functions in open systems: A Feynman-Vernon influence functional approach
Jan Tuziemski
Recent theoretical and experimental studies have shown significance of quantum information scrambling (i.e. a spread of quantum information over a system degrees of freedom) for pr…
Decoherence of spin registers revisited
Jan Tuziemski, Aniello Lampo, Maciej Lewenstein +1
We revisit decoherence process of a qubit register interacting with a thermal bosonic bath. We generalize the previous studies by considering not only the register's behavior but a…
Redundant information encoding in QED during decoherence
Jan Tuziemski, Piotr Witas, Jarosław K. Korbicz
Decoherence processes in quantum electrodynamics due to neglecting either the radiation [L. Landau, Z. Phys. 45, 430 (1927)] or the charged matter [N. Bohr and L. Rosenfeld, K. dan…
Objectivity in non-Markovian spin-boson model
Aniello Lampo, Jan Tuziemski, Maciej Lewenstein +1
Objectivity constitutes one of the main features of the macroscopic classical world. An important aspect of the quantum-to-classical transition issue is to explain how such a prope…
Information transfer during the universal gravitational decoherence
J. K. Korbicz, J. Tuziemski
Recently Pikovski et al. have proposed in [ Pikovski I et al. 2015 Nature Phys. 11, 668] an intriguing universal decoherence mechanism, suggesting that gravitation may play a conce…
Analytical studies of Spectrum Broadcast Structures in Quantum Brownian Motion
J. Tuziemski, J. K. Korbicz
Spectrum Broadcast Structures are a new and fresh concept in the quantum-to-classical transition, introduced recently in the context of decoherence and the appearance of objective…
Objectivisation In Simplified Quantum Brownian Motion Models
J. Tuziemski, J. K. Korbicz
Birth of objective properties from subjective quantum world has been one of the key questions in the quantum-to-classical transition. Basing on recent results in the field, we stud…
No quantum realization of extremal no-signaling boxes
Ravishankar Ramanathan, Jan Tuziemski, Michał Horodecki +1
Pure states are very important in any theory since they represent states of maximal information about the system within the theory. Here, we show that no non-trivial (not local rea…
On the non-locality of tripartite non-signaling boxes emerging from wirings
Jan Tuziemski, Karol Horodecki
It has been recently shown, that some of the tripartite boxes admitting bilocal decomposition, lead to non-locality under wiring operation applied to two of the subsystems [R. Gall…
Can communication power of separable correlations exceed that of entanglement resource?
Paweł Horodecki, Jan Tuziemski, Paweł Mazurek +1
The scenario of remote state preparation with shared correlated quantum state and one bit of forward communication [B. Dakic et al. Nature Physics 8, 666-670 (2012)] is considered.…
Symmetry-based estimation of lower bound on secure key rate of noisy private states
Jan Tuziemski, Paweł Horodecki
Quantum private states are the states that represent some amount of perfect secure key. A simple symmetry of any generalised private quantum state (ie. the states that represent pe…
Analytical progress on symmetric geometric discord: Measurement-based upper bounds
Adam Miranowicz, Pawel Horodecki, Ravindra W. Chhajlany +2
Quantum correlations may be measured by means of the distance of the state to the subclass of states having well defined classical properties. In particular, a geometric measur…
