Others have turned to quantum computing ETFs to spread their bets across the sector. As of mid-2026, over the past year, a basket of 11 pure-play quantum stocks tracked in this analysis has trailed the Nasdaq-100. This next-generation computing technology has massive implications for national security, so the DoD needs to take a deep interest in it. These five are headquartered outside the United States, which makes them ineligible for most federal contracts and grant programs. Early tests included sending quantum data via visible light signals — a first step toward combining quantum computing with fiber-optic communications equipment.
