Extending the Bloch sphere model to an N-qubit system

Francisco Piñero, Cristian Franco, Hernán I. de la Cruz +5

The Bloch sphere is an elegant tool for representing single-qubit states. However, a widely accepted generalization for multi-qubit systems with entanglement remains absent. We pro…

From Superradiance to Superabsorption: An Exact Treatment of Non-Markovian Cooperative Radiation

Ignacio González, Ángel Rivas

We investigate the emergence of cooperative radiation phenomena in ensembles of two-level atoms coupled to a lossy resonant cavity beyond the Markovian and mean-field approximation…

Benchmarking quantum phase-space methods for near-resonant light propagation

Mojdeh S. Najafabadi, Joel F. Corney, Luis Sanchez Soto +1

We study the dynamics of light interacting with a near-resonant atomic medium using the truncated Wigner and positive P phase-space representations. The atomic degrees of freedom a…

Phenomenological Noise Models and Optimal Thresholds of the 3D Toric Code

Ji-Ze Xu, Yin Zhong, Miguel A. Martin-Delgado +2

Three-dimensional (3D) topological codes offer the advantage of supporting fault-tolerant implementations of non-Clifford gates, yet their performance against realistic noise remai…

Efficient and simple Gibbs state preparation of the 2D toric code via duality to classical Ising chains

Pablo Páez-Velasco, Niclas Schilling, Samuel O. Scalet +2

We introduce the notion of polynomial-depth duality transformations, which relates two sets of operator algebras through a conjugation by a poly-depth quantum circuit, and make use…

Experimental characterization of the hierarchy of quantum correlations in top quark pairs

Yoav Afik, Regina Demina, Alan Herrera +3

Recent results from the Large Hadron Collider have demonstrated quantum entanglement of top quark-antiquark pairs using the spin degrees of freedom. Based on the doubly differentia…
