Entanglement on a surface chip using scalable control technologies for trapped ion qubits

Daisy Smith (9231587)

A blueprint for a scalable quantum computer using microwave radiation and a lattice of microfabricated surface ion traps was first proposed by Lekitsch et al. [1] in 2017. These surface ion traps require an integrated current-carrying wire layer which produces a variable magnetic field gradient at the position of the ions. Such a surface trap was first presented by Siegele et al. [2] in 2022. This thesis outlines the first use-case of this trap, demonstrating single-qubit control and characterization using long-wavelength radiation, and discusses the use of an Arbitrary Waveform Generator as a more scalable method for this qubit control. The thesis then characterizes the current-carrying wires, using the hyperfine states of 171Yb+ to demonstrate a variable and controllable gradient. In a magnetic field gradient, the use of a dressed state can greatly increase the coherence time of qubits, as presented by [3], the dressed state is created on this surface trap for the first time. Finally maximal entanglement of spin and motion, as proposed by Mintert and Wunderlich in [4], is shown in a single ion using long-wavelength radiation and using the current-carrying wires to produce the gradient.

Experimental Methods for Trapping Ions Using Microfabricated Surface Ion Traps

Seokjun Hong, Minjae Lee, Yeong‐Dae Kwon +2 more

Ions trapped in a quadrupole Paul trap have been considered one of the strong physical candidates to implement quantum information processing. This is due to their long coherence time and their capability to manipulate and detect individual quantum bits (qubits). In more recent years, microfabricated surface ion traps have received more attention for large-scale integrated qubit platforms. This paper presents a microfabrication methodology for ion traps using micro-electro-mechanical system (MEMS) technology, including the fabrication method for a 14 µm-thick dielectric layer and metal overhang structures atop the dielectric layer. In addition, an experimental procedure for trapping ytterbium (Yb) ions of isotope 174 (174Yb+) using 369.5 nm, 399 nm, and 935 nm diode lasers is described. These methodologies and procedures involve many scientific and engineering disciplines, and this paper first presents the detailed experimental procedures. The methods discussed in this paper can easily be extended to the trapping of Yb ions of isotope 171 (171Yb+) and to the manipulation of qubits.
