Signatures of the Optical Stark Effect on Entangled Photon Pairs from Resonantly Pumped Quantum Dots
Basso Basset F, Rota M, Beccaceci M, Krieger T, Buchinger Q, Neuwirth J, et al.
Phys Rev Lett
. 2023 Nov;
131(16):166901.
PMID: 37925701
Two-photon resonant excitation of the biexciton-exciton cascade in a quantum dot generates highly polarization-entangled photon pairs in a near-deterministic way. However, the ultimate level of achievable entanglement is still debated....

Seidelmann T, Schimpf C, Bracht T, Cosacchi M, Vagov A, Rastelli A, et al.
Phys Rev Lett
. 2022 Nov;
129(19):193604.
PMID: 36399754
Entangled photon pairs are key to many novel applications in quantum technologies. Semiconductor quantum dots can be used as sources of on-demand, highly entangled photons. The fidelity to a fixed...

Basso Basset F, Rota M, Schimpf C, Tedeschi D, Zeuner K, Covre da Silva S, et al.
Phys Rev Lett
. 2019 Nov;
123(16):160501.
PMID: 31702339
Photonic entanglement swapping, the procedure of entangling photons without any direct interaction, is a fundamental test of quantum mechanics and an essential resource to the realization of quantum networks. Probabilistic...

Muller M, Vural H, Schneider C, Rastelli A, Schmidt O, Hofling S, et al.
Phys Rev Lett
. 2017 Jul;
118(25):257402.
PMID: 28696738
Multiphoton entangled states such as "N00N states" have attracted a lot of attention because of their possible application in high-precision, quantum enhanced phase determination. So far, N00N states have been...

Chen P, Katcho N, Feser J, Li W, Glaser M, Schmidt O, et al.
Phys Rev Lett
. 2013 Oct;
111(11):115901.
PMID: 24074107
It has been highly debated whether the thermal conductivity κ of a disordered SiGe alloy can be lowered by redistributing its constituent species so as to form an ordered superlattice....

Trotta R, Zallo E, Ortix C, Atkinson P, Plumhof J, van den Brink J, et al.
Phys Rev Lett
. 2012 Oct;
109(14):147401.
PMID: 23083282
The lack of structural symmetry which usually characterizes semiconductor quantum dots lifts the energetic degeneracy of the bright excitonic states and hampers severely their use as high-fidelity sources of entangled...

Phys Rev Lett
. 2012 Sep;
109(8):085502.
PMID: 23002758
Self-assembled Ge wires with a height of only 3 unit cells and a length of up to 2 micrometers were grown on Si(001) by means of a catalyst-free method based...

Adv Mater
. 2012 Apr;
24(20):2668-72.
PMID: 22499442
We integrate resonant-cavity light-emitting diodes containing quantum dots onto substrates with giant piezoelectric response. Via strain, the energy of the photons emitted by the diode can be precisely controlled during...

107(21):217402.
PMID: 22181923
We apply external uniaxial stress to tailor the optical properties of In(x)Ga(1-x)As/GaAs quantum dots. Unexpectedly, the emission energy of single quantum dots controllably shifts to both higher and lower energies...

PMID: 21230984
The shape of coherent SiGe islands epitaxially grown on pit-patterned Si(001) substrates displays very uniform collective oscillations with increasing Ge deposition, transforming cyclically between shallower "dome" and steeper "barn" morphologies....
