Quantum-Information Processing in Semiconductor Quantum Dots
Filippo Troiani, Ulrich Hohenester, Elisa Molinari · physica status solidi (b) · 2001
We propose an all-optical implementation of quantum-information processing in semiconductor quantum dots, where electron–hole excitations (excitons) serve as the computational degrees of freedom (qubits). The strong dot confinement leads to a strong renormalization of excitonic states, which, in analogy to NMR-based implementations of quantum-information processing, can be exploited for performing conditional and unconditional qubit operations.
