# Influence of qubits' nonradiative decay into a common bath on the transport properties of microwave photons

## TL;DR

This paper investigates how nonradiative decay of qubits into a shared environment affects microwave photon transport in a 1D microstrip line, revealing significant differences from previous models.

## Contribution

It introduces a non-Hermitian Hamiltonian approach to explicitly account for indirect qubit interactions via nonradiative decay, advancing understanding of photon transport.

## Key findings

- Nonradiative decay alters transmission and reflection properties.
- Indirect qubit interactions significantly impact photon transport.
- Results differ markedly from previous models without nonradiative effects.

## Abstract

We consider the influence of nonradiative damping of qubits on the microwave transport of photons, propagating in an open one-dimensional microstrip line. Within the framework of the formalism of a non-Hermitian Hamiltonian we obtained the expressions for the transmission and reflection coefficients for two qubits which explicitly account for the indirect interaction between qubits due to nonradiative decay into common bath. It is shown that this interaction leads to the results that are significantly different from those already known
