A shift from charge-based paradigms to spin and light is essential for computing.

History

Historical Context

The development of quantum computing began in 1980 when Paul Benioff proposed the quantum Turing machine, building on Alan Turing's earlier work. Richard Feynman later emphasized the limitations of classical computers in simulating quantum systems. Today, advancements in materials like chalcogenides and ongoing challenges in quantum decoherence highlight the historical evolution and potential of quantum technologies in computation and photonics.
