Closed Quantum Boltzmann Bridges: Coherent Revivals, Hidden Microstates, and the Emergence of Classical Two-Time Entropy Conditioning
Sina Kazemian, Ghazal Farhani, Younes Javanmard
The classical Boltzmann Bridge describes entropy histories conditioned on both an initial low-entropy macrostate and a later macrostate. Unlike the usual past-only formulation of t…
Coefficient-Decoupled Matrix Product Operators as an Interface to Linear-Combination-of-Unitaries Circuits
Younes Javanmard
We introduce a coefficient-decoupled matrix product operator (MPO) representation for Pauli-sum operators that separates reusable symbolic operator support from a tunable coefficie…
Quantum Markov chain Monte Carlo method with programmable quantum simulators
Mauro D'Arcangelo, Younes Javanmard, Natalie Pearson
In this work, we present a quantum Markov chain algorithm for many-body systems that utilizes a special phase of matter known as the Many-Body Localized (MBL) phase. We show how th…
Duality between string and computational order in symmetry-enriched topological phases
Paul Herringer, Vir B. Bulchandani, Younes Javanmard +2
We present the first examples of topological phases of matter with uniform power for measurement-based quantum computation. This is possible thanks to a new framework for analyzing…
