Bulk-boundary correspondence from hyper-invariant tensor networks
Rafał Bistroń, Mykhailo Hontarenko, Karol Życzkowski
We introduce a tensor network designed to faithfully simulate the AdS/CFT correspondence, akin to the multi-scale entanglement renormalization ansatz (MERA), following hyper-invari…

Fidelity decay and error accumulation in random quantum circuits
Nadir Samos Sáenz de Buruaga, Rafał Bistroń, Marcin Rudziński +3
We present a comprehensive analysis of fidelity decay and error accumulation in faulty quantum circuit models. Our work devises an analytical bound for the average fidelity between…

Tristochastic operations and convolutions of quantum states
Rafał Bistroń, Wojciech Śmiałek, Karol Życzkowski
The notion of convolution of two probability vectors, corresponding to a coincidence experiment can be extended for a family of binary operations determined by (tri)stochastic tens…
