The path to the current state of quantum computing has been marked by a series of pioneering milestones:

1998: Discovery of the Shor algorithm, demonstrating quantum computers' potential to shatter traditional encryption methods, leading to a quest for quantum-resistant cryptography.
2001: Development of the first quantum bit (qubit) by Yale University researchers, paving the way for the practical realization of quantum computing.
2012: Unveiling of the D-Wave One, the first commercially available quantum computer, albeit with limited capabilities, sparking widespread interest in this nascent technology.
2019: Google's groundbreaking announcement of quantum supremacy, demonstrating a quantum computer outperforming its classical counterparts in a specific computational task.

Contemporary Landscape of Quantum Computing

The contemporary landscape of quantum computing is characterized by a vibrant ecosystem of research and development, intense competition among industry leaders, and a burgeoning startup scene.
