Why is my awareness here, while yours is over there? Why is the universe split in two for each of us, into a subject and an infinity of objects? How is each of us our own center of experience, receiving information about the rest of the world out there? Why are some things conscious and others apparently not? Is a rat conscious? A gnat?

Quantum consciousness is a speculative concept that attempts to explain consciousness and related phenomena through the lens of quantum mechanics, a branch of physics that deals with the behavior of particles at the smallest scales. While the idea is intriguing and has garnered interest among some scientists and philosophers, it remains highly controversial and lacks empirical evidence to support it conclusively.

The basic premise of quantum consciousness posits that consciousness arises from quantum processes occurring within the brain, potentially involving phenomena such as quantum superposition, quantum entanglement, and quantum coherence. Proponents of this idea suggest that quantum effects at the molecular or subcellular level may play a role in cognitive processes and subjective experiences, leading to the emergence of consciousness.

However, several challenges and criticisms confront the concept of quantum consciousness:
