The intricate dance between quantum mechanics and the Heart Sūtra's philosophical insights illuminates the enigmatic nature of the universe. This paper ventures into the wave-particle duality inherent in quantum mechanics and its unexpected alignments with the ancient wisdom encapsulated in the Heart Sūtra, revealing a reality not as a steadfast entity but as a spectrum of potentialities that morphs in the wake of observation. A pivotal focus is on the duality's emphasis on emptiness and existence, pushing the boundaries of conventional thought. Quantum mechanics, intriguingly, reverberates with Buddhist ideologies, especially the intertwined nature of all phenomena. This alignment finds further resonance in the Trikāya doctrine, clarifying reality at the quantum level to the observable material reality. As the exploration into the universe's depths continues, the Heart Sūtra emerges as a crucial beacon, underscoring the all-encompassing nature of existence and the transformative potential of the Prajnaparamita. This paper marries the Heart Sūtra's teachings with quantum science's revelations, bridging the ancient spiritual realm and contemporary scientific frontiers. Through this confluence of ancient wisdom and modern science, the paper offers an enriched perspective for spiritual and scientific scholars, emphasizing the intertwined fabric of reality.

Complementarity is one of the central mysteries of quantum mechanics, dramatically illustrated by the wave-particle duality in Young's double-slit experiment, and famously regarded by Feynman as "impossible, absolutely impossible to describe classically, [and] which has in it the heart of quantum mechanics" (emphasis original).1 The overarching goal of this thesis is to demonstrate that complementarity is also at the heart of quantum information theory, that it allows us to make (some) sense of just what information "quantum information" refers to, and that it is useful in understanding and constructing quantum information processing protocols.
