For decades, a few researchers have speculated that quantum-mechanical phenomena, such as wave interference and superposition, may play an important role in consciousness, but concrete evidence remains elusive. Moreover, two arguments were often raised against the quantum brain hypothesis (Jedlicka, 2017):
Specifically, Koch and Hepp (2006) wrote:
Although the brain is unlikely to be a quantum system, the mind could be. According to mind-body dualism, the mind is an entity distinct from the brain. Conscious perception of a scene is imprinted in the mind, not the brain. Thus, the information about perceived scenes is stored in the "mind" whose physical nature remains to be elucidated. In Part I, it has been proposed that the mind is a quantum-mechanical system composed of gravitational (GR) and electromagnetic (EM) waves emitted from ions in ion channels.
Remarkably, a growing number of researchers believed that the photon-based qubits (Slussarenko and Pryde, 2019) could be a more promising approach to quantum computing. Psi Quantum, a startup company that has raised over $200M since 2016, claims: "A useful quantum computer requires at least a million qubits.....Photonics is the only way to deliver 1,000,000 qubits."
The "bit" is a basic unit of information in computing and digital communications. A "qubit" refers to the quantum bit in quantum information processing. Like the classical bit, a "qubit" also has two basis states, usually denoted as "0" and "1". However, qubits can exhibit quantum phenomena such as superposition between basis states and entanglement among qubits.
Further details are discussed in the following sections.
