Coherent interaction-free detection of noise
John J. McCord, Shruti Dogra, Gheorghe Sorin Paraoanu
The measurement and characterization of noise is a flourishing area of research in mesoscopic physics. In this work, we propose interaction-free measurements as a noise-detection t…
High-fidelity robust qubit control by phase-modulated pulses
Marko Kuzmanović, Isak Björkman, John J. McCord +2
We present a set of robust and high-fidelity pulses that realize paradigmatic operations such as the transfer of the ground state population into the excited state and arbitrary $X…
Theory of coherent interaction-free detection of pulses
John J. McCord, Shruti Dogra, Gheorghe Sorin Paraoanu
Quantum physics allows an object to be detected even in the absence of photon absorption by the use of so-called interaction-free measurements. We provide a formulation of this pro…
Integrated conversion and photodetection of virtual photons in an ultrastrongly coupled superconducting quantum circuit
Luigi Giannelli, Giorgio Anfuso, Miroslav Grajcar +3
The ground-state of an artificial atom ultrastrongly coupled to quantized modes is entangled and contains an arbitrary number of virtual photons. The problem of their detection has…
Detecting virtual photons in ultrastrongly coupled superconducting quantum circuits
Luigi Giannelli, Elisabetta Paladino, Miroslav Grajcar +2
Light-matter interaction and understanding the fundamental physics behind is essential for emerging quantum technologies. Solid-state devices may explore new regimes where coupling…
