“ Quantum physics", a phrase people often associate with complexity. With this revolutionary discovery that contrasts with classical physics, the physics of macro objects which most students learn in school, in terms of scale and principles, it is no wonder that we find quantum physics such a mysterious topic. However, this complicated topic may just be the key to fulfilling your childhood dream, teleportation. In this blog, we will be exploring the basics of quantum physics and discovering how it may lead us to the dream of teleportation.
Quantum physics is the branch of physics that deals with micro objects, such as subatomic particles and atoms. It sets the foundation of explaining the behavior of matter and energy at this atomic level scale. Yet, it also challenges our classical understanding of how the world works.
Here's how it goes: in a sealed box, a cat, a radioactive atom, a Geiger counter, poison, and a hammer are placed. The atom has a 50% chance of decaying, triggering the poison if decay is detected. In classical physics, the cat is either alive or dead. In quantum mechanics, until observed, the cat exists in a superposition of both alive and dead states. This is due to the uncertain state of the atom, which simultaneously decays and doesn't decay until observed. Superposition describes this simultaneous existence of multiple states, challenging classical intuitions.

Another key concept is quantum entanglement, where if two particles are entangled, their properties become linked in such a way that the state of one particle instantly affects the other, regardless of the distance between them.
So how does the following concepts potentially lead to quantum teleportation?
Imagine a teleportation platform that can scan the quantum state of an object. While scanning, the object's state is represented as a combination of multiple possible states, each with its own probability of location. This superposition of states allows for all the relevant information about the object to be encoded into the teleportation particles. These encoded particles are then entangled with a corresponding set of particles at the destination, ensuring that once the object is disassembled to an atomic level, it can be reassembled back to its original state at the destination through the quantum information.
Though conceptually teleportation seems feasible, it still remains firmly within the realm of fiction for now due to a set of challenges.
The quantum complexity of human bodies with trillions of particles, each with its own quantum state is crazily complex. Not only is the scanning of the quantum state hard but the disassembling and reassembling of the human body at the quantum level would likely be astronomical, far beyond our current technological capabilities.
It truly is disappointing that teleportation is so near yet so far. As we continue to advance our knowledge of quantum physics, who knows what the future may hold for the boundaries of human exploration and discovery?
Maybe even you, the one who is reading this blog, will become the next Issac Newton.
