Quantum complexity phase transitions in monitored random circuits by Ryotaro Suzuki, Jonas Haferkamp, Jens Eisert, Philippe Faist

“…In our proof, we make use of percolation theory to find paths along which an exponentially long quantum computation can be run below the critical rate, and to identify events where the state complexity is reset to zero above the critical rate. …”

Computational Swarming: A Cultural Technique for Generative Architecture by Sebastian Vehlken

“…By taking advantage of the self-organisational capabilities of computational agent collectives whose global behaviour emerges from the local interaction of a large number of relatively simple individuals (as it does, for instance, in animal swarms), architects are able to understand buildings and urbanscapes in a novel way as complex spaces that are constituted by the movement of multiple material and informational elements. …”

A low-complexity detection algorithm for quadrature spatial modulation systems by Kai LUO, Junwei HUANG, Pengguang ZHOU, Hao XU, Can WU

“…To tackle the issues of the uncertainty number of the activated antennas and high computational complexity of maximum likelihood (ML) detection algorithm in quadrature spatial modulation (QSM),a low-complexity detec-tion algorithm was proposed.Firstly,the system model was reconstructed into a new model suitable for low-complexity detection algorithms in fixed active antennas systems based on compressed sensing (CS) signal re-construction theory.Then,based on the idea of orthogonal matching pursuit (OMP) algorithm and reconstructed model,a candidate set of activated antennas was obtained.Lastly,using ML algorithm to search the candidate,the index of activated antennas and the modulation symbol were selected.Simulation results show that the proposed de-tector is capable of achieving about 90% reduction in complexity with low performance loss compared with ML al-gorithm.…”
