Quantum magnonics with engineered dissipative and coherent interactions
Debsuvra Mukhopadhyay, Jayakrishnan M. P. Nair, Girish S. Agarwal
Cavity magnonics is moving beyond the conventional paradigm of coherent spin--photon hybridization toward the controlled engineering of dissipative and coherent interactions, Floqu…
Emergent non-Markovianity in time-delayed waveguide QED
Debsuvra Mukhopadhyay, Stuart J. Masson
Quantum systems are invariably coupled to a surrounding environment. A common theoretical method to simplify the problem is to trace over the environment under a Markov approximati…
Practical Limits to Single-Mode Vacuum Squeezing with a SNAIL Parametric Amplifier
Theodore Shaw, Debsuvra Mukhopadhyay, Zhuoqun Hao +4
We characterize single-mode vacuum squeezing generated by a SNAIL Parametric Amplifier (SPA) operated under conditions representative of practical sensing and qubit-readout experim…
Quantum Multiphoton Rabi Oscillations in Waveguide QED
Debsuvra Mukhopadhyay, Jung-Tsung Shen
The future of quantum information processing hinges on chip-scale nanophotonics, specifically cavity QED and waveguide QED. One of the foremost processes underpinning quantum photo…
Quantum amplification of spin currents in cavity magnonics by a parametric drive induced long-lived mode
Debsuvra Mukhopadhyay, Jayakrishnan M. P. Nair, G. S. Agarwal
Cavity-mediated magnon-magnon coupling can lead to a transfer of spin-wave excitations between two spatially separated magnetic samples. We enunciate how the application of a two-p…
Cavity mediated level attraction and repulsion between magnons
Jayakrishnan M. P. Nair, Debsuvra Mukhopadhyay, Girish S. Agarwal
We characterize some of the distinctive hallmarks of magnon-magnon interaction mediated by the intracavity field of a microwave cavity, along with their testable ramifications. In…
Coupling Quantum Antennas to Fibers and Waveguides
Girish S. Agarwal, Debsuvra Mukhopadhyay
We present a brief overview of the transport of quantum light across a one-dimensional waveguide which is integrated with a periodic string of quantum-scale dipoles. We demonstrate…
Anti-PT-symmetry-enhanced interconversion between microwave and optical fields
Debsuvra Mukhopadhyay, Jayakrishnan M. P. Nair, Girish S. Agarwal
The intrinsic dissipation of systems into a shared reservoir introduces coherence between two systems, enabling anti-Parity-Time (anti-PT) symmetry. In this paper, we propose an an…
Quantum Fisher Information Perspective on Sensing in Anti-PT Symmetric Systems
J. Wang, D. Mukhopadhyay, G. S. Agarwal
The efficient sensing of weak environmental perturbations via special degeneracies called exceptional points in non-Hermitian systems has gained enormous traction in the last few d…
Ultralow threshold bistability and generation of long-lived mode in a dissipatively coupled nonlinear system: application to magnonics
Jayakrishnan M. P. Nair, Debsuvra Mukhopadhyay, Girish S. Agarwal
The prospect of a system possessing two or more stable states for a given excitation condition is of topical interest with applications in information processing networks. In this…
Roadmap on Integrated Quantum Photonics
Galan Moody, Volker J. Sorger, Daniel J. Blumenthal +52
Integrated photonics is at the heart of many classical technologies, from optical communications to biosensors, LIDAR, and data center fiber interconnects. There is strong evidence…
Enhanced sensing of weak anharmonicities through coherences in dissipatively coupled anti-PT symmetric systems
Jayakrishnan M. P. Nair, Debsuvra Mukhopadhyay, G. S. Agarwal
In the last few years, the great utility of PT-symmetric systems in sensing small perturbations has been recognized. Here, we propose an alternate method relevant to dissipative sy…
Transparency in a periodic chain of quantum emitters strongly coupled to a waveguide
Debsuvra Mukhopadhyay, Girish S. Agarwal
We demonstrate the emergence of transparent behavior in a chain of periodically spaced non-identical quantums emitters coupled to a waveguide, in the special case when the inter-at…
Multiple Fano interferences due to waveguide-mediated phase-coupling between atoms
Debsuvra Mukhopadhyay, Girish S. Agarwal
We examine quantum interference effects due to absorption and emission from multiple atoms coupled to a waveguide and highlight the modifications they entail in regards to single-p…
