Scalable quantum networks and devices using erbium ions integrated with silicon nanophotonics
Abstract
Devices capable of storing and processing quantum states of information will createfundamentally new technological capabilities for computing, communication and sensing. In thiswork, we explore a new physical platform for quantum information processing. In this implementation, the quantum bits are individual erbium atom impurities in a solid crystal ofyttrium orthosilicate. The individual atoms are manipulated and measured using light propagatingin photonic integrated circuits. This system is advantageous compared to prior work with otheratomic impurities because the properties of the erbium ion (namely, its optical transitionwavelength of 1.5 microns) are compatible with mature silicon-based photonic circuits, whichhave extremely low loss and can be mass-produced.In this work, we will carry out the initial characterization of the properties of single erbiumions, which have not previously been observed. In particular, we will study the ions’ optical andspin properties, and how they interact with each other, to understand how they can best be used tostore and process quantum states. With this knowledge, we will construct prototype devices forquantum communications networks and quantum computers.
