Abstract

We present a scheme to generate arbitrary superpositions of Dicke states of excitons in optically driven quantum dots. The proposal is based on a sequence of laser pulses to control transitions between the nearest-neighbor Dicke states appropriately. It is shown that only N laser pulses are needed to generate arbitrary superpositions of Dicke states of N quantum dots.

GEOMETRIC PHASE OF DICKE STATE OF EXCITONS IN N COUPLED QUANTUM DOTS

D. M. Tong, L. C. Kwek, Christophe Couteau +1 more

We investigate the nature of geometric phases generated by the evolution of the superposition of Dicke states of excitons in N coupled quantum dots. Based on a sequence of laser pulses, arbitrary superposition of the Dicke states of excitons can be generated. By properly choosing the superposition and using the controllable laser pulses, geometric phase with any expected value can be realized. The main advantage of using coupled quantum dots is that one uses a collective behavior, rather than addressing individually qubits, for instance, like with trapped ions configuration, which require a heavy setup in order to perform a gate.

Generation of arbitrary quantum state in a high-Q cavity

Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis

We present a scheme to generate arbitrary superposition of the Fock states in a high-Q cavity. This proposal is based on a sequence of laser pulses, which are tuned appropriately to control transitions on Fock state. It is shown that N laser pulses are needed to generate a pure state with a phonon number limit $N$.

Quantum entanglement and information processing via excitons in optically driven quantum dots

John Henry Reina, Luis Quiroga, Neil F. Johnson

We show how optically driven coupled quantum dots can be used to prepare maximally entangled Bell and Greenberger-Horne-Zeilinger states. Manipulation of the strength and duration of the selective light pulses needed for producing these highly entangled states provides us with crucial elements for the processing of solid-state-based quantum information. Theoretical predictions suggest that several hundred single quantum bit rotations and controlled-NOT gates could be performed before decoherence of the excitonic states takes place.

Decoherence Effects on the Generation of Exciton Entangled States in Coupled Quantum Dots

Ferney J. Rodríguez, Luis Quiroga, Neil F. Johnson

We report on exciton-acoustic-phonon coupling effects on the generation of exciton maximally entangled states in N = 2 and 3 quantum dot systems. In particular, we address the question of the combined effect of laser pulses, appropriate for generating Bell and Greenberger-Horne-Zeilinger entangled states, together with decoherence mechanisms as provided by a phonon reservoir. By solving numerically the master equation for the optically driven exciton–phonon kinetics, we show that the generation of maximally entangled exciton states is preserved over a reasonable parameter window.

Creating excitonic entanglement in quantum dots through the optical Stark effect

Ahsan Nazir, Brendon W. Lovett, G. Andrew D. Briggs

We show that two initially nonresonant quantum dots may be brought into resonance by the application of a single detuned laser. This allows for control of the interdot interactions and the generation of highly entangled excitonic states on the picosecond time scale. Along with arbitrary single-qubit manipulations, this system would be sufficient for the demonstration of a prototype excitonic quantum computer.

Tunneling-assisted coherent population transfer and creation of coherent superposition states in triple quantum dots

Si-Cong Tian, Ren-Gang Wan, Lijie Wang +3 more

Abstract A scheme is proposed for coherent population transfer and creation of coherent superposition states assisted by one time-dependent tunneling pulse and one time-independent tunneling pulse in triple quantum dots. Time-dependent tunneling, which is similar to the Stokes laser pulse used in traditional stimulated Raman adiabatic passage, can lead to complete population transfer from the ground state to the indirect exciton states. Time-independent tunneling can also create double dark states, resulting in the distribution of the population and arbitrary coherent superposition states. Such a scheme can also be extended to multiple quantum dots assisted by one time-dependent tunneling pulse and more time-independent tunneling pulses.
