Ultimate quantum limit for amplification: a single atom in front of a mirror
Emely Wiegand, Ping-Yi Wen, Per Delsing +2
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional semi-infinite waveguide. We consider two setups where a…
Classification and reconstruction of optical quantum states with deep neural networks
Shahnawaz Ahmed, Carlos Sánchez Muñoz, Franco Nori +1
We apply deep-neural-network-based techniques to quantum state classification and reconstruction. We demonstrate high classification accuracies and reconstruction fidelities, even…
Synthesizing electromagnetically induced transparency without a control field in waveguide QED using small and giant atoms
Andreas Ask, Yao-Lung L. Fang, Anton Frisk Kockum
The absorption of photons in a three-level atom can be controlled and manipulated by applying a coherent drive at one of the atomic transitions. The situation where the absorption…
Tunable Chiral Bound States with Giant Atoms
Xin Wang, Tao Liu, Anton Frisk Kockum +2
We propose tunable chiral bound states in a system composed of superconducting giant atoms and a Josephson photonic-crystal waveguide (PCW), with no analog in other quantum setups.…
Quantum State Tomography with Conditional Generative Adversarial Networks
Shahnawaz Ahmed, Carlos Sánchez Muñoz, Franco Nori +1
Quantum state tomography (QST) is a challenging task in intermediate-scale quantum devices. Here, we apply conditional generative adversarial networks (CGANs) to QST. In the CGAN f…
Engineering the Level Structure of a Giant Artificial Atom in Waveguide Quantum Electrodynamics
A. M. Vadiraj, Andreas Ask, T. G. McConkey +4
Engineering light-matter interactions at the quantum level has been central to the pursuit of quantum optics for decades. Traditionally, this has been done by coupling emitters, ty…
