The Coming Market for Quantum Repeaters: A Ten-Year Market Forecast

Report IQT-MQR2022-1222
Published November 9, 2022

Publish Date: December 2022

Several years ago, IQT Research was the first research firm ever to forecast the market for quantum repeaters. We have always believed that the quantum repeater is the enabling technology that will propel the Quantum Internet from a disconnected collection of testbeds to an integrated network capable of carrying qubits. In this new report, IQT Research provides the analysis on what the value of the quantum repeater market will be and who the main contenders are in supplying quantum repeaters at a commercial level.

The introduction of optical amplifiers into the fiber optic networks in the 1980s and 1990s transformed optical networking into a global platform for high-speed data communications and we believe something similar will happen as quantum repeaters are installed in the network. In analyzing who will be the winners and losers in the quantum repeater stakes, we take into consideration vendors’ technology and marketing strengths as well their connections to the marketplace. This report also describes at a granular level the various approaches to building quantum repeaters and tier one companies and research centers developing them.

Repeaters provide the ability to build distributed quantum networks connecting quantum devices such as quantum sensors and quantum computers and therefore potentially quantum repeaters create huge amounts of value for carriers, equipment vendors and component makers. But many challenges remain as do big differences of opinion on how quantum repeaters can be built most profitably. This report will provide a “guide for the perplexed” on where the money will be made and where it will be lost in the quantum repeater market to come.
