Derivation of the quantum-optical master equation based on coarse-graining of time
Kevin Fischer
This is a derivation of the quantum-optical master equation using coarse-graining of time, which brings new insights into a decades old technique. My derivation is quite similar to…
Scattering into one-dimensional waveguides from a coherently-driven quantum-optical system
Kevin A. Fischer, Rahul Trivedi, Vinay Ramasesh +2
We develop a new computational tool and framework for characterizing the scattering of photons by energy-nonconserving Hamiltonians into unidirectional (chiral) waveguides, for exa…
Signatures of two-photon pulses from a quantum two-level system
Kevin A. Fischer, Lukas Hanschke, Jakob Wierzbowski +5
The theoretical community has found interest in the ability of a two-level atom to generate a strong many-body interaction with light under pulsed excitation. Single-photon generat…
Strongly Cavity-Enhanced Spontaneous Emission from Silicon-Vacancy Centers in Diamond
Jingyuan Linda Zhang, Shuo Sun, Michael J. Burek +11
Quantum emitters are an integral component for a broad range of quantum technologies including quantum communication, quantum repeaters, and linear optical quantum computation. Sol…
Pulsed Rabi oscillations in quantum two-level systems: beyond the Area Theorem
Kevin A. Fischer, Lukas Hanschke, Malte Kremser +3
The Area Theorem states that when a short optical pulse drives a quantum two-level system, it undergoes Rabi oscillations in the probability of scattering a single photon. In this…
Ultrafast Coherent Manipulation of Trions in Site-Controlled Nanowire Quantum Dots
K. G. Lagoudakis, P. L. McMahon, C. Dory +9
Physical implementations of large-scale quantum processors based on solid-state platforms benefit from realizations of quantum bits positioned in regular arrays. Self-assembled qua…
Observation of Mollow Triplets with Tunable Interactions in Double Lambda Systems of Individual Hole Spins
K. G. Lagoudakis, K. A. Fischer, T. Sarmiento +7
Although individual spins in quantum dots have been studied extensively as qubits, their investigation under strong resonant driving in the scope of accessing Mollow physics is sti…
Complete Coherent Control of Silicon-Vacancies in Diamond Nanopillars Containing Single Defect Centers
Jingyuan Linda Zhang, Konstantinos G. Lagoudakis, Yan-Kai Tzeng +8
Arrays of identical and individually addressable qubits lay the foundation for the creation of scalable quantum hardware such as quantum processors and repeaters. Silicon vacancy c…
Nonclassical Light Generation from III-V and Group-IV Solid-State Cavity Quantum Systems
Marina Radulaski, Kevin Fischer, Jelena Vuckovic
In this chapter, we present the state-of-the-art in the generation of nonclassical states of light using semiconductor cavity quantum electrodynamics (QED) platforms. Our focus is…
