If Humans Had Souls, Would They Be Quantum?

Quantum computing is challenging everything we thought we knew about technology, time, and even human consciousness. Some scientists theorize that some of the ways quantum computers process information may resemble how the human brain works. Others take it even further, wondering whether quantum properties of these machines could help explain consciousness—or what humans might think of as the soul. At the heart of this mystery is time. Quantum mechanics bends and stretches our understanding of time, which could hold the key to quantum computing, the nature of thought, and what it means to be alive.

To appreciate this, it helps to understand what makes quantum different from regular computers. Everyday computers process information in a straightforward, linear way—using bits that are either 1s or 0s. This is similar to how we experience time, one moment after another. Quantum computers, however, use qubits, which can exist in a state of quantum superposition, meaning they can be two things at the same time. In this case, they can be both 1 and 0 at the same time. This allows quantum computers to potentially take multiple paths forward at the same time—perhaps much like human neurons firing in complex patterns—when doing a calculation, rather than just one path forward like a traditional computer does. This makes quantum computers more powerful than traditional computers because they leverage this quantum ability to coordinate computations more efficiently and steer toward optimal solutions faster. This allows them to solve certain problems exponentially faster than traditional computers.

Then there’s entanglement, another quantum phenomenon. When two qubits become entangled, they somehow remain connected, no matter how far apart they are. If one changes, the other changes instantly, flying in the face of our normal understanding of space and time. In quantum computing, this allows for incredibly fast, complex problem-solving. And it raises huge questions—if time doesn’t behave the way we think, could the same be true for human consciousness?

Some researchers believe quantum effects like superposition and entanglement might also be happening inside our brains. Unlike computers, which process data in a step-by-step fashion, human thought isn’t always logical or linear. We jump between ideas, experience déjà vu, or recall vivid memories out of nowhere. A theory called orchestrated objective reduction (Orch-OR), developed by renowned physicist Roger Penrose and anesthesiologist Stuart Hameroff, suggests that quantum interactions inside microtubules—tiny structures in brain cells—may be responsible for consciousness. If they’re right, then the brain isn’t just a powerful supercomputer—it’s a quantum computer and one that processes experiences in ways far beyond traditional computers.

Not everyone agrees. Many argue that the brain is too warm and chaotic for quantum effects to function. Quantum mechanics as we know it today requires carefully controlled, ultra-cold environments—nothing like the warm, constantly firing neurons going off in a human brain. While microtubules exist in brain cells, there’s no proof they act as quantum processors. Until scientists find solid evidence of quantum activity in the brain, most researchers believe consciousness is better explained by well-known biological and neural processes.

That said, if quantum activity in the brain is verified, and quantum mechanics is related to human consciousness, it raises some remarkable questions. For example, in physics, information is never destroyed—it only changes form. Some scientists suggest that if the mind operates like a quantum system, then consciousness might continue to exist beyond death, just as quantum information persists beyond the machine that computes it—similar to how theologians throughout history describe the soul, which is not bound to the body.

If true, this would challenge everything we think we know about life and time. Some physicists already believe time is just an illusion, created by the way our brains process reality. If consciousness is quantum, maybe time isn’t something we pass through in a straight line. Maybe past, present, and future are connected in ways we don’t fully understand. Think about your last experience of déjà vu, which may have felt stronger than reality itself. Maybe quantum physics offers a sort-of-scientific bridge between mind and matter, or even consciousness.

If the brain does operate on quantum principles, it could redefine our understanding of intelligence, consciousness, and time. Maybe time isn’t just a road moving forward. Maybe it’s something we navigate in ways far more complex than we ever imagined. For now, quantum physics still leaves us with more questions than answers.
