Abstract:
I will introduce, discuss and demonstrate coherent optical initialization, full control and readout of spin qubits in semiconductor quantum dots: Two spin
qubits, the bright and the dark exciton (single
electronic excitation in which the excited electron is
correlated with the "hole" that it leaves in the
ground state), will be explained and demonstrated.
Both qubits, the short lived bright and the long lived
dark excitons are initiated and fully controlled
deterministically and on demand in a pure state by one optical pulse.
Our demonstrations do not require externally
applied magnetic field and they establish that these
integer spin two level systems form excellent solid
state matter qubits with some advantages over
the half integer spin qubit:
the electron and the hole, separately.
Since semiconductor nanostructures dovetail with
contemporary technologies of electronic and
photonic components these spin qubits may have
implications on implementations of quantum
technologies.
