Thinking upon it further i came up with this possible solution, reproduced from my notes:
A Potential Solution to the Teleportation Paradox
The classic teleportation paradox asks: If a machine perfectly replicates you particle-by-particle in a new location while destroying the original, is the person who arrives really you? Or has the original been murdered, and a new, identical copy created?
The State of Entangled Consciousness
The experiment begins with a crucial assumption: that it's possible to create a second, perfectly identical body in a new location. But this isn't a normal copy. For an instant, every single quantum particle in the original body is quantumly entangled with its corresponding particle in the new target body.
According to this hypothesis, this perfect entanglement creates a single, unified quantum state. Instead of two separate individuals, there is a moment where a single consciousness exists as a unified quantum state, shared between the two bodies. It is not located in one body or the other, but is a single, coherent entity.
The Problem of Decoherence
This state of perfect quantum harmony is fleeting. The universe is a noisy place, filled with countless interactions, stray photons, gravitational fluctuations, and so on. This environmental interaction causes what is called decoherence. For a complex, macroscopic system like a human body, decoherence would happen almost instantly, likely in less than a femtosecond.
The critical challenge is that there are two ways this decoherence can occur. The first is an uncontrolled decoherence, which happens naturally if the process is not managed. If the quantum state is allowed to decohere on its own, the single consciousness will split. The two bodies would each become a separate, distinct individual, leading to a duplication of consciousness. This is why the decoherence must be controlled in such a way that only the target body has the chance for the next moment of experience. For this to happen, the original body must be destroyed before either body has a chance to have its next moment of independent experience.
This distinction is crucial, as the moral and legal implications of destroying the original body depend entirely on the timing.
- If the original body is destroyed before the entangled state is created, it is simply murder.
- If the original body is destroyed after uncontrolled decoherence has occurred, it is also a form of murder, as it results in the death of one of two separate individuals.
- However, if the original body is destroyed during the moment of quantum coherence, when both bodies are part of a single, unified quantum state, the act of destruction may not be considered murder. In this scenario, the destruction is not the end of a separate life, but the final step in a transfer of a single consciousness from one state to another.
The Femtosecond Solution
To prevent this catastrophic split, the solution proposes a radical act: the immediate and complete destruction of the original body. This destruction must happen with extreme precision and speed, within the fleeting window of a femtosecond, before the next moment of conscious experience can occur and cause decoherence.
The act of destroying the original body is the act of decoherence. In the framework of quantum mechanics, this action serves as a final observation or measurement. This measurement forces the unified quantum state to collapse, but since the original body is destroyed, it only has one state left to collapse to: the target body. Because the original body is destroyed, the single shared consciousness is left with only one viable option: to continue its existence in the new, intact target body. From the perspective of the quantum system, the next moment of experience is only possible in the target body, ensuring that the consciousness was transferred, and not duplicated.
By controlling the collapse of the wave function with this precise and destructive act, the personal identity is not lost but is seamlessly transferred, ensuring the continuity of the single individual without bifurcation or multiplication.
