Development of Methods for Continuous-Variable Quantum Computing with Trapped-Ion
Abstract
Trapped ions are one of the most promising modalities for quantum computing (QC). The most widely-developed and successful implementation of trapped-ion QC consists of coherently manipulating two-level quantum systems (qubits), with each qubit in the processor encoded in the internal electronic spin states of a single ion. However, two main limitations to this approach have been the speed of quantum operations and the number of available qubits (or Hilbert space size) that can be precisely controlled. We here propose a one-year seedling to explore an alternative gate-based approach to QC that utilizes the motional bosonic states of ions for quantum information storage and processing. This approach, known as continuous-variable QC (CVQC), potentially offers a path towards substantially more efficient use of trapped ions to realize and control a Hilbert space of a given size, as well as faster quantum computing speed. In this seedling, we propose to investigate the potential of CVQC through theoretical study, while simultaneously designing and building apparatuses and ion traps capable of experimentally implementing CVQC operations.
