Simulating the Dicke Model on Qubit-Based and hybrid Qubit-Boson-Based Quantum Computers
Aravind P. Babu, Seongjin Ahn, Jing Sun +3
The Dicke model provides a fundamental description of collective light-matter interactions and has long served as a testbed for exploring a wide range of physical phenomena in quan…
Single-qubit quantum gate at an arbitrary speed
Seongjin Ahn, Kichan Park, Daehee Cho +3
Quantum information processing comprises physical processes, which obey the quantum speed limit (QSL): high speed requires strong driving. Single-qubit gates using Rabi oscillation…
Subcycle tomography of quantum light
Geehyun Yang, Matthias Kizmann, Alfred Leitenstorfer +1
Quantum light is considered to be one of the key resources of the coming second quantum revolution expected to give rise to groundbreaking technologies and applications. If the spa…
Qubit entanglement generated by classical light driving an optical cavity
Seongjin Ahn, Andrey S. Moskalenko, Vladimir Y. Chernyak +1
We study the generation of entanglement between two qubits which communicate through a single cavity mode of quantum light but have no direct interaction. We show that such entangl…
Back action in quantum electro-optic sampling of electromagnetic vacuum fluctuations
T. L. M. Guedes, I. Vakulchyk, D. V. Seletskiy +3
The influence of measurement back action on electro-optic sampling of electromagnetic quantum fluctuations is investigated. Based on a cascaded treatment of the nonlinear interacti…
Self-referenced subcycle metrology of quantum fields
Sinan Gündoğdu, Stéphane Virally, Marco Scaglia +2
We propose and analyze a new time-domain method for subcycle metrology of quantum electric fields using a combination of a 3rd order nonlinear optical process and homodyne detectio…
