Quantum Journal Club：Quasiparticle engineering and entanglement propagation in a
Abstract: The key to explaining and controlling a range of quantum phenomena is to study how information propagates around many-body systems. Quantum dynamics can be described by particle-like carrie...

Quantum Journal Club： Effects of Reduced Measurement Independence on Bell-Based
Abstract: With the advent of quantum information, the violation of a Bell inequality is used to witness the absence of an eavesdropper in cryptographic scenarios such as key distribution and randomne...

Reachability analysis of quantum Markov chains and quantum Markov decision proce
Abstract: 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 ...

Probabilistic simulations of quantum communication backward in time
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...

Free quantum field theory from general principles, without using Lorentz invaria
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...
