Telling emissions apart in a multiphoton resonance: visualizing a conditional evolution

Th. K. Mavrogordatos

We find that the phase-space representation of the electromagnetic field inside a driven cavity strongly coupled to a two-level atom can be employed to distinguish photon emissions…

Enhanced eigenvector sensitivity and algebraic classification of sublattice-symmetric exceptional points

Kang Yang, Ipsita Mandal

Exceptional points (EPs) are degeneracy of non-Hermitian Hamiltonians, at which the eigenvalues, along with their eigenvectors, coalesce. Their orders are given by the Jordan decom…

Role of parasitic interactions and microwave crosstalk in dispersive control of two superconducting artificial atoms

Alan C. Santos

In this work we study the role of parasitic interactions and microwave crosstalk in a system of two superconducting artificial atoms interacting via a single-mode coplanar waveguid…

On the Relative Distance of Entangled Systems in Emergent Spacetime Scenarios

Guilherme Franzmann, Sebastian M. D. Jovancic, Matthew Lawson

Spacetime emergence from entanglement proposes an alternative to quantizing gravity and typically derives a notion of distance based on the amount of mutual information shared acro…

Quantum Alchemy and Universal Orthogonality Catastrophe in One-Dimensional Anyons

Naim E. Mackel, Jing Yang, Adolfo del Campo

Many-particle quantum systems with intermediate anyonic exchange statistics are supported in one spatial dimension. In this context, the anyon-anyon mapping is recast as a continuo…

Gauge independent description of Aharonov-Bohm Effect

Xiang Li, Thors Hans Hansson, Wei Ku

The Aharonov-Bohm (AB) effect is a pure quantum effect that implies a measurable phase shift in the wave function for a charged particle that encircles a magnetic flux located in a…
