Top 10 Everyday Things That You Would Want to Quantum Entangle

Every physicist would love to see quantum entanglement applied in everyday life. The idea is that two objects can have a direct link established between them, regardless of the distance separating them, such that a change in one instantly affects the other. This link could be affected by any change to the quantum coordinates of one object, so that the spin state of the first can dictate the spin state of the second, regardless of distance.

Quantum entanglement has already been used to transfer encrypted information without interception, enable subatomic teleportation, and entangle quantum bits (qubits) to power quantum computers. However, our ability to use quantum entanglement is limited by the universal state of quantum equilibrium, as well as the different frequencies of waves required to interact with particles across the universe to establish known spin states.

Moreover, non-quantum (classical) objects have such an extremely low probability of exhibiting quantum behavior that they would only interact in a quantum sense after about 10^35 years. But ignoring these limitations, let's imagine: what everyday objects would you want to quantum entangle?
The Top Ten
1 Computers

This is the one that we all salivate at the idea of. Classical computers process information for calculations with individual binary codes. With a qubit, a superposition of two or more quantum states allows two calculations to be carried out at once, and entanglement with more qubits allows this figure to increase exponentially.

We'd be fully able to carry out as many calculations as there are particles within the observable universe.

2 Minds

You would literally be able to read the mind of another. There is the problem of entangling it in the first place, and possibly the effects on your brain pulses as they are forced into a certain quantum state, but this would be doubling the information processed by one mind.

In theory.

3 Switches

This would be more than simply being able to turn on a light on the other side of the world. If the input charges and currents driving transistors could be entangled, then we'd theoretically be able to operate switches within electronic devices, as well as amplifiers, in vast quantities within a given time.

We may even have a quantum network of them.

4 Telescopes

Imagine how useful this would be for astronomers. One could set an entangled array of these babies across the world, possibly even in space and mounted on other bodies in space. They would be able to track astronomical objects and pass on information to each base in an instant.

5 Communication Devices

It simply reminds me of the Moon and Earth example. The Earth is the transmitter of the signal and the Moon is the receiver. The Moon receives the signal before the signal is even transmitted from Earth.

Interstellar contact would be much easier, assuming that the aliens have the same technology and are able to determine that the link exists. And of course, this would occur without interception.

6 Lights

People say, use a parallel circuit, that way, if one light breaks, the rest don't follow. But if you could entangle the particles within a filament or within a cathode tube, running a current through one could, in theory, cause the particles within an entangled filament to vibrate and produce the same amount of heat and light.

7 Load Platforms

This could serve as a way to transport, no, teleport loads. No need for big boats. It would require one transfer of information after the other, as the information lost due to the Uncertainty Principle cannot sufficiently transfer the necessary information directly, but it can be retained within the quantum system due to entanglement.

That's the beauty of this weird, wonderful physics. The only problem is that the energy input would be huge. Ah, well, just a quirk of life.

8 Clocks

This would be a great way to measure the effects of time dilation due to relativity. Observing one clock slowing as the other is thrown into a black hole could show how these dilation effects take place.

That I would surely like to see. But whether black holes can permit entanglement is a mystery. All physical laws break down there.

9 Coding

Just like quantum computers, when two qubits share an entangled state, this doubles the information that can be retained within the system. More entangled qubits can greatly increase the density of information and result in a greater capacity of coded information.

10 GPS

Imagine if your satnav was entangled with a satellite recording your terrain, and that satellite's computer was entangled with others nearby. This would create a much more accurate tracking system.

More importantly, we could use this to land on an extraterrestrial body, like an asteroid. Instantaneous transfer of information would be essential for the statistical analysis required for touchdown, and it would be much more difficult to achieve otherwise. We would probably be able to map a surface in the very process of landing.
