Nishimori Threshold Estimation for Bayesian Inference and Surface Code Decoding
Rohit Mukherjee, Simon Trebst
In quantum error correction, the error threshold provides essential quantitative guidance for the ability to bring about fault-tolerance through decoding the effects of incoherent…
Frozonium: Freezing Anharmonicity in Floquet Superconducting Circuits
Keiran Lewellen, Rohit Mukherjee, Haoyu Guo +3
Floquet engineering is a powerful method that can be used to modify the properties of interacting many-body Hamiltonians via the application of periodic time-dependent drives. Here…
Floquet-Thermalization via Instantons near Dynamical Freezing
Rohit Mukherjee, Haoyu Guo, Debanjan Chowdhury
Periodically driven Floquet quantum many-body systems have revealed new insights into the rich interplay of thermalization, and growth of entanglement. The phenomenology of dynamic…
RKKY interaction in Weyl semimetal nanowires
Rohit Mukherjee, Asutosh Dubey
We investigate the effective couplings induced between localized impurities on the surface of a Weyl semimetal (WSM) nanowire within the framework of Ruderman--Kittel--Kasuya--Yosi…
Dynamical Freezing in Exactly Solvable Models of Driven Chaotic Quantum Dots
Haoyu Guo, Rohit Mukherjee, Debanjan Chowdhury
The late-time equilibrium behavior of generic interacting models is determined by the coupled hydrodynamic equations associated with the globally conserved quantities. In the prese…
Arresting Quantum Chaos Dynamically in Transmon Arrays
Rohit Mukherjee, Haoyu Guo, Keiran Lewellen +1
Ergodic quantum many-body systems evolving under unitary time dynamics typically lose memory of their initial state via information scrambling. Here we consider a paradigmatic tran…
