The electronic spin degrees of freedom in semiconductors typically have decoherence times that are several orders of magnitude longer than other relevant time scales. A solid-state quantum computer based on localized electron spins as qubits is therefore of potential interest. Here, a scheme that realizes controlled interactions between two distant quantum dot spins is proposed. The effective long-range interaction is mediated by the vacuum field of a high finesse microcavity. By using…

Spin-based all-optical quantum computation with quantum dots: Understanding and suppressing decoherence
We present an all-optical implementation of quantum computation using semiconductor quantum dots. Quantum memory is represented by the spin of an excess electron stored in each dot. Two-qubit gates…

Quantum interface between light and nuclear spins in quantum dots
The coherent coupling of flying photonic qubits to stationary matter-based qubits is an essential building block for quantum communication networks. We show how such a quantum interface can be…
Distributed quantum information processing via quantum dot spins
We propose a scheme to engineer a non-local two-qubit phase gate between two remote quantum-dot spins. Along with one-qubit local operations, one can in principal perform various types of distributed…
Spin-Based Quantum Information Processing in Magnetic Quantum Dots
TLDR
The system of a QD in a DMS is described in a way which allows an analysis of the decoherence due to spin waves in the DMS subsystem and methods of qubit rotation as well as two-qubit operations are suggested.
Global optical control of a quantum spin chain
Quantum processors that combine the long decoherence times of spin qubits together with fast optical manipulation of excitons have recently been the subject of several proposals. Here, I show that…
