Quantum Computing with Nuclear Spins in Semiconductors
The successful implementation of a scalable, fault-tolerant quantum computer would introduce a type of information processing more powerful than any available today. Reciprocally, the discovery of a fundamental obstacle to such a system would be an important advance in the foundations of quantum theory. No such fundamental obstacles are currently known, but neither has any architecture been sho...
متن کاملQuantum computing with spins in solids
The ability to perform high-precision oneand two-qubit operations is sufficient for universal quantum computation. For the Loss-DiVincenzo proposal to use single electron spins confined to quantum dots as qubits, it is therefore sufficient to analyze only singleand coupled double-dot structures, since the strong Heisenberg exchange coupling between spins in this proposal falls off exponentially...
متن کاملQuantum Computing with Electron Spins in Quantum Dots
We present a set of concrete and realistic ideas for the implementation of a small-scale quantum computer using electron spins in lateral GaAs/AlGaAs quantum dots. Initialization is based on leads in the quantum Hall regime with tunable spin-polarization. Read-out hinges on spin-to-charge conversion via spin-selective tunneling to or from the leads, followed by measurement of the number of elec...
متن کاملQuantum computing classical physics.
In the past decade, quantum algorithms have been found which outperform the best classical solutions known for certain classical problems as well as the best classical methods known for simulation of certain quantum systems. This suggests that they may also speed up the simulation of some classical systems. I describe one class of discrete quantum algorithms which do so--quantum lattice-gas aut...
متن کاملProspects for measurement-based quantum computing with solid state spins
This article aims to review the developments, both theoretical and experimental, that have in the past decade laid the ground for a new approach to solid state quantum computing. Measurement-based quantum computing (MBQC) requires neither direct interaction between qubits nor even what would be considered controlled generation of entanglement. Rather it can be achieved using entanglement that i...
