Abstract: 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 p...
Abstract: 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 fr...
Abstract: 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 the...
Abstract: We introduce Fermionic quantum cellular automata and describe the emergence of different geometries from their structure, under the assumptions of linearity, unitarity, locality, homogeneit...
Abstract: Quantum mechanics promises extraordinary capabilities for computation and cryptography. However, quantum information is not only fragile, but also impossible to verify directly for classica...
Abstract: In this theoretical study, we analyze quantum walks on complex networks, which model network-based processes ranging from quantum computing to biology and even sociology. Specifically, we a...
