Which Countries Have the Most Quantum Computers?

Most high-income nations have begun investing in quantum computing research, independently or in public-private partnerships and many middle-income countries have initiated pilot quantum computing programs.

However, countries encounter challenges in obtaining the resources and expertise needed for a quantum research initiative whatever their gross domestic product (GDP).

More than 20 governments worldwide have launched national quantum initiatives since 2009, investing more than $30 billion. These significant investments have the potential to drive the development of spinoffs that can make significant contributions to quantum technology while fostering innovation.

Biden Signs Executive Order Limiting US Quantum Investment in China

President Joe Biden has signed an executive order that limits U.S. citizens from investing in companies based in China, Hong Kong or Macau that work in quantum information technologies, semiconductors, microelectronics or artificial intelligence (AI). 

The executive order says that these “countries of concern” are engaged in developing these technologies, which are critical to their military, intelligence, surveillance or cyber-enabled capabilities.
