Reachability analysis of quantum Markov chains and quantum Markov decision proce
内容： We introduce the notion of quantum Markov decision process (qMDP) as a semantic model of nondeterministic and concurrent quantum programs. It is shown by examples that qMDPs can be used in anal...

Probabilistic simulations of quantum communication backward in time
内容： Like classical mechanics, quantum mechanics is a causal theory [1,2]--a theory that forbids sending messages from the future to the past. Still, one can simulate backward communication by posts...

Free quantum field theory from general principles, without using Lorentz invaria
内容： I will present an overview of the derivation of free quantum field theory (QFT) from general principles, without assuming mechanical notions and Lorentz symmetry. The framework resulting from t...

On zero-error communication via quantum channels in the presence of noiseless fe
内容： We initiate the study of zero-error communication via quantum channels assisted by noiseless feedback link of unlimited quantum capacity, generalizing Shannon's zero-error communication theory ...

Fermionic cellular automata and Quantum Fields
内容： We introduce Fermionic quantum cellular automata and describe the emergence of different geometries from their structure, under the assumptions of linearity, unitarity, locality, homogeneity an...
