SUPER and femtosecond spin-conserving coherent excitation of a tin-vacancy color center in diamond
Cem Güney Torun, Mustafa Gökçe, Thomas K. Bracht +11
The coherent excitation of an optically active spin system is one of the key elements in the engineering of a spin-photon interface. Using the novel SUPER scheme, we coherently con…
Unveiling the interplay of Mollow physics and perturbed free induction decay by nonlinear optical signals of a dynamically driven two-level system
Jan M. Kaspari, Thomas K. Bracht, Katarina Boos +4
Nonlinear optical signals in optically driven quantum systems can reveal coherences and thereby open up the possibility for manipulation of quantum states. While the limiting cases…
Temperature-independent almost perfect photon entanglement from quantum dots via the SUPER scheme
Thomas K. Bracht, Moritz Cygorek, Tim Seidelmann +2
Entangled photon pairs are essential for quantum communication technology. They can be generated on-demand by semiconductor quantum dots, but several mechanisms are known to reduce…
Compact Chirped Fiber Bragg Gratings for Single-Photon Generation from Quantum Dots
Vikas Remesh, Ria G. Krämer, René Schwarz +10
A scalable source of single photons is a key constituent of an efficient quantum photonic architecture. To realize this, it is beneficial to have an ensemble of quantum emitters th…
Controlling the Photon Number Coherence of Solid-state Quantum Light Sources for Quantum Cryptography
Yusuf Karli, Daniel A. Vajner, Florian Kappe +14
Quantum communication networks rely on quantum cryptographic protocols including quantum key distribution (QKD) using single photons. A critical element regarding the security of Q…
Signatures of dynamically dressed states
Katarina Boos, Sang Kyu Kim, Thomas Bracht +10
The interaction of a resonant light field with a quantum two-level system is of key interest both for fundamental quantum optics and quantum technological applications employing re…
Two-photon excitation with finite pulses unlocks pure dephasing-induced degradation of entangled photons emitted by quantum dots
Tim Seidelmann, Thomas K. Bracht, Barbara Ursula Lehner +7
Semiconductor quantum dots have emerged as an especially promising platform for the generation of polarization-entangled photon pairs. However, it was demonstrated recently that th…
