Experimental Issues in Coherent Quantum-State Manipulation of Trapped Atomic Ions( Book )

2 editions published in 1998 in English and held by 7 WorldCat member libraries worldwide

Methods for, and limitations to, the generation of entangled states of trapped atomic ions are examined. As much as possible, state manipulations are described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is central to the creation of entanglement. Keeping with current interest, some experimental issues in the proposal for trapped-ion quantum computation by J.I. Cirac and P. Zoller (University of Innsbruck) are discussed. Several possible decoherence mechanisms are examined and what may be the more important of these are identified. Some potential applications for entangled states of trapped-ions which lie outside the immediate realm of quantum computation are also discussed
Cooled Ion Frequency Standard( Book )

7 editions published between 1982 and 1991 in English and held by 7 WorldCat member libraries worldwide

The purpose of this work is to develop techniques to overcome the fundamental limits of present frequency standards--the second and residual first-order Doppler shifts. To this end we study suitable frequency reference transitions in ions which are stored on electromagnetic traps and cooled by radiation pressure to <1K. (Author)

Liquid and Solid Ion Plasmas( Book )

4 editions published between 1989 and 1992 in English and held by 4 WorldCat member libraries worldwide

Atomic ions which are stored in electromagnetic fields are an example of nonneutral plasmas. Laser techniques allow control of plasma angular momentum and provide plasma cooling to temperatures much less than 1K. Using imaging techniques, plasma spatial information is achieved. Laser spectroscopic techniques allow measurement of plasma velocity distribution functions. Liquid and solid behavior of ion plasmas is studied. Keywords: Liquid plasmas; Solid plasmas; Plasma distribution functions; Penning trap; Laser cooling

Transport of trapped-ion qubits within a scalable quantum processor by R. Bradford Blakestad( )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

Multidimensional arrays incorporating junctions would enable ions selected from arbitrary locations to be grouped together for multi-qubit gates. However, excitation of the harmonic motion of the ions during transport can negatively impact computational fidelity. Here I report a novel ion-trap design including an 'X' junction. Reliable transport of 9Be+ ions through this array has been demonstrated with motional excitation corresponding to less than one quantum in the local confining potential. The process of designing and building the trap, as well as producing the control potentials that shuttle the ions will be described. In addition, sources of motional excitation will be discussed

Quantum Measurement with Correlated Atoms( Book )

2 editions published in 1997 in English and held by 2 WorldCat member libraries worldwide

We investigate, theoretically and experimentally, ways to generate quantum mechanically correlated states between ensembles of atomic particles. The theoretical goals are: determine the best correlated states for particular applications and devise ways to generate these states and ways to measure them. The experimental goals are: demonstrate the increase in signal-to-noise ratio in spectroscopy using correlated particles, and apply stimulated Raman transitions for generation of the correlated states on transitions of general interest including microwave and optical transitions

Coherent Ion Transport in a Multi-electrode Trap Array by Ryan Bowler( )

1 edition published in 2015 in English and held by 2 WorldCat member libraries worldwide

Quantum information processors are predicted to enable a significant speedup in solving certain classes of problems compared to their classical counterparts. For one scheme of a processor implementation, required elements include qubits with long coherence times, laser-induced universal gates, information transport, and motional-state initialization using a second coolant ion species. Techniques described in this thesis include the use of a multiple electrode segmented trap, wherein information transport is achieved through the transport of qubit ions between spatially distinct locations. While experiment timescales had previously been dominated by ion transport and re-cooling of motional states, I have achieved transport and separation of qubit ions on timescales comparable to quantum logic gates. This work has been extended to achieve fast transport of qubit and coolant two-species ion chains. The developed techniques for ion transport result in low motional excitations, reducing the need for re-initialization of ion motional states. This can enable significant improvement in the operation time of an ion-based quantum information processor
Quantum entanglement generation in trapped ions using coherent and dissipative methods by Yiheng Lin( )

1 edition published in 2015 in English and held by 2 WorldCat member libraries worldwide

Entangled states are a key resource in fundamental quantum physics, quantum cryptography, and quantum computation. In this thesis, we focus on the demonstrations of two novel methods to generate entanglement. First, we implement dissipative production of a maximally entangled steady state on two trapped ions. Dissipative and coherent processes are combined and implemented in a continuous time-independent fashion, analogous to optical pumping of atomic states, continuously driving the system towards the steady entangled state. With this method, we obtain a Bell state fidelity up to 0.89(2). Second, we propose and demonstrate a novel coherent process to confine quantum evolution in a subspace between an initial separable state and the target entangled state. We demonstrate this scheme on two and three ions obtaining a Bell state fidelity up to 0.992(2). Both of these methods are robust against certain types of experimental noise and decoherence. Additionally, we demonstrate sympathetic cooling of ion chains to near the ground state of motion with an electromagnetically-induced-transparency (EIT) method. This results in roughly an order of magnitude faster cooling time while using significantly lower laser power compared to the conventional resolved sideband cooling method. These techniques may be helpful for scaled-up quantum computing

Quantum Measurement with Entangled Atoms( Book )

2 editions published in 2001 in English and held by 2 WorldCat member libraries worldwide

We investigate, theoretically and experimentally, methods to generate quantum mechanically entangled states of ensembles of atomic particles. The theoretical goals are: determine the best entangled states for particular applications and devise ways to generate these states and ways to measure them. The experimental goals are: demonstrate the increase in signal-to-noise ratio in spectroscopy using entangled particles, and find effective means to create the desired entangled states for particular measurements. We have created entangled states of two and four trapped (9)Be(+) ions in a single-step, deterministic way. These states are those desired for spectroscopy with higher signal-to-noise ratio than possible with unentangled atoms. The procedure can be scaled to large numbers of ions. We have identified causes of imperfect fidelity and are taking actions to eliminate these causes

High-Fidelity Entangling Gates with Trapped-Ions by Ting Rei Tan( )

1 edition published in 2016 in English and held by 2 WorldCat member libraries worldwide

Quantum entangling logic gates are key ingredients for the implementation of a quantum information processing device. In this thesis, we focus on experimental implementations of three types of entangling geometric-phase gates with trapped ions, which rely on the effective spin-spin interactions generated with state-dependent forces. First, a mixed-species entangling gate is demonstrated using a beryllium and a magnesium ion to create a Bell state with a fidelity of 0.979(1). Combined with single-qubit gates, we use this mixed-species gate to implement controlled-NOT and SWAP gates. Second, we implement a high-fidelity universal gate set with beryllium ions. Single-qubit gates with error per gate of 3.8(1)x10 -5 are achieved. By creating a Bell state with a deterministic two-qubit entangling gate, we deduce a gate error as low as 8(4)x10-4. Third, a novel two-qubit entangling gate with dynamical decoupling built-in is demonstrated with a fidelity of 0.974(4). This gate is robust against qubit dephasing errors and offers simplifications in experimental implementation compared to some other gates with trapped ions. Errors in the above implementations are evaluated and methods to further reduce imperfections are discussed. In a separate experiment, correlated measurements made on pairs of ions violate a "chained" Bell inequality obeyed by any local-realistic theory. The lowest chained Bell inequality parameter determined from our measurements is 0.296(12), this value is significantly lower than 0.586, the minimum value derived from a perfect Clauser-Horne-Shimony-Horne (CHSH) Bell inequality experiment. Furthermore, our CHSH Bell inequality results provide a device-independent certification of the deterministically created Bell states
