Quantum phenomena are typically observable at length and time scales smaller than those
of our everyday experience, often involving individual particles or excitations. The past few …

There is rapidly expanding interest in exploiting the spin of valence-band holes rather than
conduction-band electrons for spin qubit semiconductor circuits composed of coupled …

Gate-defined quantum dots (QDs) are such a highly-tunable quantum system in which single
spins can be electrically coupled, manipulated, and measured. However, the spins in gate …

We present a detailed investigation of different excitonic states weakly confined in single
GaAs/AlGaAs quantum dots obtained by the Al droplet-etching method. For our analysis we …

We present an experimental study of the coherence properties of a single heavy-hole spin
qubit formed in one quantum dot of a gated GaAs/AlGaAs double quantum dot device. We …

Electrical tunability of the g-factor of a confined spin is a long-time goal of the spin qubit field.
Here we utilize the electric dipole spin resonance (EDSR) to demonstrate it in a gated GaAs …

Difference in g factors in multidot structures can form the basis of dot-selective spin
manipulation under global microwave irradiation. Employing electric dipole spin resonance …

Persistent photoconductivity of GaAs/AlGaAs heterostructures has hampered the
measurement of charge-and spin-related quantum effects in gate-defined quantum devices …

Dopant-free lateral p–n junctions in the GaAs/AlGaAs material system have attracted interest
due to their potential use in quantum optoelectronics (eg, optical quantum computers or …

Electron spins in gate-defined lateral quantum dots (QDs) are a suitable platform for qubits
and have the capacity for coherent coupling to free-space photons. Superposition state …
