Quantum Computing with Trapped Particles in Microscopic Potentials

Abstract

We review recent proposals for performing entanglement manipulation via controlled interactions between trapped atoms. State-dependent, time-varying microscopic potentials allow one to obtain with high fidelity a conditional phase shift realizing a universal quantum gate. We discuss possible physical implementations with existing experimental techniques, for example optical lattices and magnetic micro-traps.

Entangling neutral atoms for quantum information processing

Tommaso Calarco, Hans J. Briegel, Dieter Jaksch +2 more

We review recent proposals for performing entanglement manipulation via cold collisions between neutral atoms. State-dependent, time-varying trapping potentials allow one to control the interaction between atoms, so that conditional phase shifts realizing a universal quantum gate can be obtained with high fidelity. We discuss possible physical implementations with existing experimental techniques, for example optical lattices and magnetic micro-traps.

Quantum gates with neutral atoms: Controlling collisional interactions in time-dependent traps

Tommaso Calarco, Edward A. Hinds, Dieter Jaksch +3 more

We theoretically study specific schemes for performing a fundamental two-qubit quantum gate via controlled atomic collisions by switching microscopic potentials. In particular we calculate the fidelity of a gate operation for a configuration where a potential barrier between two atoms is instantaneously removed and restored after a certain time. Possible implementations could be based on microtraps created by magnetic and electric fields, or potentials induced by laser light.

Quantum control and information processing in optical lattices

Poul Jessen, D. L. Haycock, Gerd Klose +3 more

Neutral atoms offer a promising platform for single- and many-body quantum control, as required for quantum information processing. This includes excellent isolation from the decohering influence of the environment, and the existence of well developed techniques for atom trapping and coherent manipulation. We present a review of our work to implement quantum control and measurement for ultra-cold atoms in far-off-resonance optical lattice traps. In recent experiments we have demonstrated coherent behavior of mesoscopic atomic spinor wavepackets in optical double-well potentials, and carried out quantum state tomography to reconstruct the full density matrix for the atomic spin degrees of freedom. This model system shares a number of important features with proposals to implement quantum logic and quantum computing in optical lattices. We present a theoretical analysis of a protocol for universal quantum logic via single qubit operations and an entangling gate based on electric dipole-dipole interactions. Detailed calculations including the full atomic hyperfine structure suggests that high-fidelity quantum gates are possible under realistic experimental conditions.

Physical representation of universal quantum gates for a trapped ion

G. Drobný, Pavol Gustafik

We discuss possibilities of quantum manipulations of trapped ions from the perspective of quantum information processing. We show how from a restricted set of feasible microscopic interactions a physical implementation of an arbitrary unitary operator can be realized. An example is given for the discrete Fourier transform. The synthesis of operators enables to realize universal quantum gates to process unknown input qubits which can be encoded into vibrational levels of trapped ions. We discuss also problem of an arbitrary measurement which can be performed using quantum gates.

Entanglement of Atoms via Cold Controlled Collisions

We show that by using cold controlled collisions between two atoms one can achieve conditional dynamics in moving trap potentials. We discuss implementing two qubit quantum gates and efficient creation of highly entangled states of many atoms in optical lattices.

Towards controlling larger quantum systems: from laser cooling to quantum computing

Martin Weitz

Laser-cooling techniques offer novel opportunities in the generation and manipulation of entangled quantum states. Atoms trapped in infrared mesoscopic optical lattices are presented as attractive candidates for both the production of highly entangled states and quantum logic experiments. Recent experimental work on the realization of such a lattice, based on atoms trapped in the antinodes of an infrared standing wave near 10.6 /spl mu/m, is reviewed. This culminates in the individual lattice sites being resolved with an optical microscope. Finally, with the aim of achieving greater control over molecules, a matter-wave interferometer is proposed, in which the probability for absorption of photon momenta depends on the particle velocity, rather than on the absolute laser detuning from a particular optical transition. This scheme has prospects for the laser cooling of both atoms and molecules.
