The phrase "giant leap" or "quantum leap" has been used by the World Economic Forum (WEF) in several contexts, generally to describe a significant advancement or transformative change in a particular field. 

Key contexts in which the term appears

• Fourth Industrial Revolution (4IR): The seamless integration of the virtual and physical worlds in "cyber-physical systems" was described by the WEF as "the giant leap we see today" in industry, eclipsing previous industrial revolutions in scale.
• Technology and Innovation: The term "quantum leap" is frequently used in discussions about the transformative potential of quantum computing and the need for businesses and nations (especially in Africa) to become "quantum-ready" for the future era of technology and cybersecurity.
• Climate Action: The WEF has highlighted reports and initiatives that describe significant steps towards sustainability. For example, the organization shared a report on social media noting that "China is taking a giant leap towards decarbonization with green hydrogen".
• Global Development Scenarios: The independent "Earth for All" initiative, which involves various global experts, uses a "Giant Leap" scenario in its models as a positive pathway for humanity to live within safe and just planetary boundaries, in contrast to a "Too Little, Too Late" scenario.
• Specific Projects: "Project Leap" is a Bank for International Settlements (BIS) initiative advancing research on quantum-safe cryptography for financial systems, an effort noted in a WEF article. Additionally, "Quantum Leap Africa" is an organization listed as a partner on the WEF website. 

In summary, the term is not a single, specific, named WEF initiative itself, but rather a descriptor used in numerous articles and discussions hosted or published by the WEF to emphasize major progress or the potential for future, large-scale transformations.
