Optical fibre-based (plug-and-play) single photon source using InAsP quantum dot nanowires and gradient-index lens collection
David B. Northeast, John F. Weber, Dan Dalacu +5
We present a compact, fibre-coupled single photon source using gradient-index (GRIN) lenses and an InAsP semiconductor quantum dot embedded within an InP photonic nanowire waveguid…
In-situ tuning of individual position-controlled nanowire quantum dots via laser-induced intermixing
Alexis Fiset-Cyr, Dan Dalacu, Sofiane Haffouz +4
We demonstrate an in-situ technique to tune the emission energy of semiconductor quantum dots. The technique is based on laser-induced atomic intermixing applied to nanowire quantu…
The visibility study of S-T Landau-Zener-Stückelberg oscillations without applied initialization
G. Granger, G. C. Aers, S. A. Studenikin +4
Probabilities deduced from quantum information studies are usually based on averaging many identical experiments separated by an initialization step. Such initialization steps beco…
Enhanced charge detection of spin qubit readout via an intermediate state
S. A. Studenikin, J. Thorgrimson, G. C. Aers +5
We employ an intermediate excited charge state of a lateral quantum dot device to increase the charge detection contrast during the qubit state readout procedure, allowing us to in…
A phonon scattering assisted injection and extraction based terahertz quantum cascade laser
E. Dupont, S. Fathololoumi, Z. R. Wasilewski +6
A novel lasing scheme for terahertz quantum cascade lasers, based on consecutive phonon-photon-phonon emissions per module, is proposed and experimentally demonstrated. The charge…
Quantum interference between three two-spin states in a double quantum dot
S. A. Studenikin, G. C. Aers, G. Granger +5
Qubits based on the singlet (S) and the triplet (T0, T+) states in double quantum dots have been demonstrated in separate experiments. It has been recently proposed theoretically t…
Coherent control of three-spin states in a triple quantum dot
L. Gaudreau, G. Granger, A. Kam +6
Spin qubits involving individual spins in single quantum dots or coupled spins in double quantum dots have emerged as potential building blocks for quantum information processing a…
Influence of electron-acoustic phonon scattering on off-resonant cavity feeding within a strongly coupled quantum-dot cavity system
S. Hughes, P. Yao, F. Milde +9
We present a medium-dependent quantum optics approach to describe the influence of electron-acoustic phonon coupling on the emission spectra of a strongly coupled quantum-dot cavit…
Gate Adjustable Coherent Three and Four Level Mixing in a Vertical Quantum Dot Molecule
C. Payette, S. Amaha, T. Hatano +6
We study level mixing in the single particle energy spectrum of one of the constituent quantum dots in a vertical double quantum dot by performing magneto-resonant-tunneling spectr…
