Fast universal parametric spin control in an acoustically modulated quantum dot
Mateusz Kuniej, Michał Gawełczyk
Quantum communication, distributed computing, and hybrid architectures rely on nodes enabling coherent control of qubits and coupling to propagating quantum modes. While semiconduc…
Higher-harmonic acoustic control of laser-dressed quantum-dot states at sub-Rabi frequencies
Mateusz Kuniej, Paweł Machnikowski, Michał Gawełczyk
Acoustic control and coupling of quantum systems via phonons can enable miniaturized on-chip quantum devices. Optically active quantum dots (QDs) are essential for such platforms,…
Direct access to the initial polarization of nuclei by measuring coherence evolution of an nitrogen-vacancy center spin qubit
Mateusz Kuniej, Katarzyna Roszak
We introduce a method for the measurement of the lower bound on the initial polarization of spinful nuclei in a diamond by following the coherence evolution of an NV center spin qu…
Hybrid acousto-optical spin control in quantum dots
Mateusz Kuniej, Paweł Machnikowski, Michał Gawełczyk
Mechanical degrees of freedom very weakly couple to spins in semiconductors. The inefficient coupling between phonons and single electron spins in semiconductor quantum dots (QDs)…
Hybrid acousto-optical swing-up state control in a quantum dot
Mateusz Kuniej, Paweł Machnikowski, Michał Gawełczyk
State transfer between different quantum systems is key for successful quantum technologies. Over long distances, photons are irreplaceable, but on short ranges in miniaturized com…
Estimation of nuclear polarization via discrete measurement of NV center spin evolution
Mateusz Kuniej, Katarzyna Roszak
We propose a method for the estimation of the initial polarization of spinful nuclei of the 13 C isotope in diamond via a measurement of the evolution of the coherence of an NV cen…
InP-based single-photon sources operating at telecom C-band with increased extraction efficiency
A. Musiał, M. Mikulicz, P. Mrowiński +7
In this work we demonstrate a triggered single-photon source operating at the telecom C-band with photon extraction efficiency exceeding any reported values in this range. The non-…
