During the last few decades, different techniques have been developed for building the main component of quantum computers, i.e. quantum bits (qubits), including superconducting loops, spin-based quantum dots, coupled quantum wire and diamond vacancies to name a few.
Trapped Ions (TI) devices are leading candidates for building qubits for quantum computing. Existing methods of creating TI require designing/manufacture complex micro/nano fabricated devices and extensive use of laser sources to cool down ions and entrap them. These methods are typically very expensive and are not easily scalable for harnessing a large quantity of trapped ions.
A scalable method/device for creating TI could enable utilization of multiple qubits to perform necessary computational tasks, propelling the pursuit of practical quantum computation.
Description of the invention
Inspired by the transport of water molecules in naturally occurring proteins, researchers at the University of Waterloo have invented a novel, simple, and low-cost method to trap ions inside artificial water channels. This new method circumvents the need of using bulky lasers and expensive micro-nano fabrication techniques, thereby creating an unparallel potential of a scalable multi-qubit system.
- Improved gate fidelity and long coherence for stable qubits
