Scientists Aim To Teleport An Entire Human, This New Quantum Tech Can Make It Possible

By: Michelle | Birds Advice

Teleportation has long been a staple of science fiction, capturing imaginations with the idea of instant travel from one place to another. But what if this concept is closer to reality than most people think? Quantum teleportation, a process that transfers information rather than physical matter, has already been successfully demonstrated with particles in labs, open air, and even space.

Now, with rapid advancements in quantum computing and ongoing experiments, some scientists believe that teleporting an entire human may no longer be a distant fantasy. The possibilities are exciting, but the challenges ahead are just as immense. From accurately replicating an individual’s quantum state to handling vast amounts of information, the road to human teleportation is filled with hurdles that push the boundaries of modern technology.

From Particles To Potential Human Applications

Quantum teleportation, first theorized in in 1993 by Charles H. Bennett and his team at IBM, introduced the concept that objects could be teleported using the principles of quantum mechanics. The idea, which relies on the phenomenon of quantum entanglement, was put to the test in 1997 when researchers led by Dik Bouwmeester successfully demonstrated the process in a controlled laboratory setting. This marked a significant step toward making quantum teleportation a reality.

In 2004, a major milestone was achieved when researchers from the University of Vienna and the Austrian Academy of Sciences successfully conducted a long-distance quantum teleportation experiment across the River Danube. The experiment utilized an 800-meter optical fibre, routed through a public sewer tunnel beneath the river, to establish a quantum channel between two distant labs. The team demonstrated the teleportation of photon polarization states with remarkable accuracy, overcoming environmental challenges such as temperature fluctuations and signal loss. According to the study published in Nature, the experiment achieved teleportation fidelities surpassing classical limits, confirming the feasibility of quantum teleportation in real-world conditions​.

Lastly, some studies and reports suggest that teleportation may not be confined to theoretical physics. Chinese scientists have reportedly documented instances of teleporting physical objects under controlled conditions, which challenge conventional scientific understanding. Declassified government documents have also hinted at experiments where objects were observed to disappear from one location and reappear in another. While these reports remain controversial and lack mainstream acceptance, they fuel curiosity about the true potential of teleportation​.

The Promise of Subatomic Teleportation

Is teleportation actually possible? In a way, yes—scientists have successfully teleported the state of a single particle.

Teleportation isn’t just a science fiction dream—scientists have already achieved it on a subatomic level. Through quantum entanglement, researchers have successfully teleported the state of single particles, such as photons, over significant distances. This phenomenon allows two entangled particles to instantly share information, no matter how far apart they are.

According to the National Science Foundation, this process works by using a third particle that transfers its state to two entangled particles, effectively linking them across space. While fascinating, it’s important to note that this does not involve the physical transfer of matter, but rather the transfer of quantum states.

Despite these advancements, human teleportation remains far beyond our reach. Unlike particles, replicating an entire human with perfect accuracy would require an unimaginable amount of data. Many scientists argue that such an endeavour may never be possible due to the complexity of human biology and the limitations of current technology.

For now, the focus remains on using quantum entanglement for advancements in fields like quantum computing and secure communication, where it’s potential to revolutionize data transfer is already showing promise.

The Role of Quantum Computing In Teleportation

A critical aspect of quantum teleportation is the development of robust quantum error correction (QEC) techniques. Without QEC, fragile quantum states would quickly degrade, making reliable teleportation impossible. QEC is essential for protecting quantum information from errors due to decoherence and other quantum noise. Recent advancements have demonstrated that as quantum processors scale, their error rates can decrease, marking a significant step toward practical quantum computing. For instance, Google’s recent work called quantum computers has shown that increasing the number of qubits in their system led to a reduction in logical qubit error rates, a promising development for the field.

Scalability remains a formidable challenge in quantum computing. Distributing quantum circuits across a network of quantum computers is one approach to facilitate large computations using current quantum technologies. Research has explored methods for distributing quantum circuits, aiming to minimize the resources required for communication between quantum processors. These efforts are crucial for building scalable quantum systems capable of supporting complex operations like quantum teleportation.

The Reality of Human Teleportation

Teleporting particles is one thing, but scaling that technology to transport an entire human? That’s an entirely different challenge. Despite these promising developments, teleporting a human remains an extraordinary challenge. Achieving this feat would require capturing and replicating the precise quantum state of an astronomical number of atoms, a task far beyond the reach of current technology. Nonetheless, the advancements continue to push the boundaries of what is possible in quantum physics. As scientists refine their methods and technologies, quantum teleportation holds immense potential for secure communication, quantum computing, and possibly, one day, revolutionizing transportation as we know it. Let’s break down some of the biggest hurdles standing in the way.

Complexity of Replicating A Human

The human body isn’t just a collection of atoms—it’s a highly intricate system composed of around 10^27 atoms, each made up of smaller particles like quarks and muons, all with their own unique quantum states. Before quantum mechanics, it was assumed that teleportation would involve physically disintegrating matter and reassembling it elsewhere. However, quantum entanglement suggests that it’s not the matter itself being transported, but rather the information that defines it.

The Heisenberg uncertainty principle makes it even trickier. This fundamental principle of quantum mechanics states that certain pairs of properties—such as position and momentum—cannot be precisely measured at the same time. That means there’s no way to gather the exact data needed to perfectly reconstruct a person elsewhere, as the original values can never be fully known or replicated.

Moreover, the no-cloning theorem in quantum mechanics, first articulated by Wootters and Zurek in 1982, states that it is impossible to create an exact copy of an arbitrary unknown quantum state. This fundamental principle imposes significant limitations on the possibility of human teleportation.

Keeping Quantum States Intact

Another major issue is quantum decoherence, which happens when quantum states interact with their environment and lose their delicate state. Even minor disturbances, such as temperature fluctuations or electromagnetic interference, can corrupt quantum data. Scientists are working on error correction methods to tackle this problem, but right now, it’s a long way from being reliable enough for something as complex as a human body.

The Massive Computational Load

Even if scientists figure out how to capture and protect all that quantum data, they’d still need an enormous amount of computing power to process it. Since atoms in the human body are fundamentally no different from those in a rock or a rubber ball, the challenge lies in arranging them correctly based on quantum information. Teleporting a person would require handling an astronomical amount of information—far beyond what today’s quantum computers can manage. Current systems, like those from Google and IBM, are making strides, but they’re still in their early stages and can only handle small-scale computations with relatively high error rates.

The Bigger Questions

Beyond the technical side, teleportation brings up some big philosophical and ethical questions. If a person is broken down into their quantum components and reassembled elsewhere, are they still the same individual, or just a copy? What happens to consciousness? And who takes responsibility if something goes wrong? These concerns raise moral and legal implications that must be addressed before teleportation could ever move beyond theoretical research.

Public Opinions On Human Teleportation

The concept of human teleportation, while captivating, raises profound ethical and philosophical questions. Discussions on Reddit reveal diverse perspectives, ranging from scientific curiosity to philosophical debates. A central concern is whether teleportation equates to a form of self-destruction. If the process involves disassembling an individual’s atoms at point A and reassembling them at point B, does the original person cease to exist, leaving only a replica behind? This dilemma challenges our understanding of identity and continuity of consciousness. As one Reddit user pondered, ” If teleportation turn you essentially into atoms and reasambles you someplace else does that mean your original body that was at point A is dead and what forms at point B is essentially a clone?”

Another layer to this ethical quandary involves the concept of the soul. In scenarios where a soul is considered integral to human existence, questions arise about its transferability during teleportation. As discussed in a Reddit thread, “If there is a soul, will that not return to the newly formed version of yourself?” Some believe that without a soul, teleportation might be ethically questionable, while others argue that as long as consciousness is preserved, the process could be considered valid. As one Redditor put it, “The Star Trek method is essentially murder,” reflecting ongoing scepticism about whether teleportation can truly maintain the essence of a person.

The Future of Teleportation—Science or Fiction?

While human teleportation remains an extraordinary challenge, the progress made in quantum teleportation cannot be overlooked. Scientists have successfully transferred the state of particles across vast distances, opening doors to ground-breaking applications in communication and computing. However, the sheer complexity of human biology presents significant barriers that current technology cannot yet overcome.

Still, the pursuit of teleportation continues to fuel scientific curiosity and innovation. Whether or not humans will ever experience instantaneous travel, the exploration of quantum mechanics is reshaping our understanding of the universe—one particle at a time.
