Abstract—Quantum technologies attracted much attention
for their disruptive potential in last two decades. The article
analyzes the worldwide patent landscape for quantum
technologies based on data extracted from Derwent Innovation
and Web of Science. The quantum technologies were grouped
into three distinct technology areas of quantum computing,
quantum communication and quantum sensing, to demonstrate
detailed development and trends respectively. It shows that
quantum technology is a highly competitive research field, and
United States, China and Japan are the most prominent
countries, in particular China made a great progress in recent
years. United States has a significant advantage in the field of
quantum computing, which is the most promising field,
meanwhile China has a significant advantage in the field of
quantum communication and succeeds in launching a quantum
Index Terms—Patent analysis, quantum communication, quantum computing, quantum sensing.
