No More Silicon? Company Develops Glass CPU for Quantum Computing
AQT, Honeywell, and Oxford Ionics are three other companies focusing on the trapped ion philosophy to enable quantum computing scaling.

IonQ, a Maryland-based company with ties to the University of Duke and its Duke Quantum Center, has recently announced the development of a new, glass-based trapped-ion computing chip which replaces their previous works with silicon-based designs.
This glass trap technology is based on etching micrometer-level-precision in fused silica glass, which will then contain the company's new computing units - reconfigurable chains of ion-based qubits. Possibility of scaling? At least triple-digits, in the current state of the technology. The company previously offered 32-qubit machines to customers, having delivered systems to major cloud services providers, including Microsoft Azure, Amazon Web Services, and Google Cloud. The company is calling their new architecture "reconfigurable multicore quantum architecture" - RMQA, for short.
