Coherence generation, symmetry algebras and Hilbert space fragmentation
Faidon Andreadakis, Paolo Zanardi
Hilbert space fragmentation is a novel type of ergodicity breaking in closed quantum systems. Recently, an algebraic approach was utilized to provide a definition of Hilbert space…
Operational Quantum Mereology and Minimal Scrambling
Paolo Zanardi, Emanuel Dallas, Faidon Andreadakis +1
In this paper we will attempt to answer the following question: what are the natural quantum subsystems which emerge out of a system's dynamical laws? To answer this question we fi…
No ((n, k, d < 127)) code can violate the quantum Hamming bound
Emanuel Dallas, Faidon Andreadakis, Daniel Lidar
It is well-known that pure quantum error correcting codes (QECCs) are constrained by a quantum version of the Hamming bound. Whether impure codes also obey such a bound, however, r…
Scrambling of Algebras in Open Quantum Systems
Faidon Andreadakis, Namit Anand, Paolo Zanardi
Many quantitative approaches to the dynamical scrambling of information in quantum systems involve the study of out-of-time-ordered correlators (OTOCs). In this paper, we introduce…
