Revisiting QCD-induced little inflation with chiral density wave state and its implications on pulsar timing array gravitational-wave signals
Tae Hyun Jung, Seyong Kim, Jong-Wan Lee +2
We revisit QCD-induced little inflation in which the Universe begins with a large baryon chemical potential and undergoes a strong first-order QCD phase transition, generating an o…

The random coupled-plaquette gauge model and the surface code under circuit-level noise
Manuel Rispler, Davide Vodola, Markus Müller +1
We map the decoding problem of the surface code under depolarizing and syndrome noise to a disordered spin model, which we call the random coupled-plaquette gauge model (RCPGM). By…

Fundamental thresholds for computational and erasure errors via the coherent information
Luis Colmenarez, Seyong Kim, Markus Müller
Quantum error correcting (QEC) codes protect quantum information against environmental noise. Computational errors caused by the environment change the quantum state within the qub…
