# Top Ten Everyday Things That You Would Want to Quantum Entangle

Every physicist wants this in everyday life. The idea that any two objects can have a direct link imposed between them, irrespective of distance between them, such that one retains the information of the other instantly when one is subject to a change. This may be affected by any change to the quantum co-ordinates of one, such that the spin state of the first can dictate that of the second, from any separations from tiny to huge. Quantum entanglement has already been responsible for transfer of encrypted information without interception, subatomic teleportation, and entanglement of quantum bits (qubits) to make quantum computers. The limit to our use of quantum entanglement is the universal state of quantum equilibrium, as well as the various sets of frequencies of waves which we'd have to apply to particles throughout the universe to achieve known spin states. And there's also the fact that non-quantum objects have such a remote probability function associated with quantum behaviour that they will not interact in a quantum sense for 10^35 years. But ignoring that, what would you want quantum entangled?### The Top Ten

*1*

**Computers**

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, this allows two calculations to be carried out at once, and entanglement with more qubits allows this figure to increase exponentially. So we'd be fully able to carry out as many calculations as there are particles within the observable universe.

Ah, great ideas and great list.

*2*

**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.

*3*

**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.

... For reasons of my own that have very little or nothing to do with science.

*4*

**Telescopes**

Imagine how useful this would be for astronomers. One could set an entangled array of these babies across the world, and possibly others in space and mounted on other bodies in space, and 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 of the signal. The moon receives the signal before the signal is even being transmitted from the earth in the first place.

Interstellar contact made much easier, assuming that the aliens have the same technology and are able to determine that the link exists. And of course, 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*

**Clocks**

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

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

*8*

**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. Only problem is that the energy input would be huge. Ah, well, just a quirk of life.

*9*

**Coding**

Just like quantum computers, when two qubits share an entangled state, this doubles the information that can be retained within the system. The more entangled qubits can greatly increase the density of information, and can 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 entangled with others nearby. A much more accurate tracking system. But something more important would be using this to land on an extraterrestrial body, say, an asteroid. Instantaneous transfer of information would be essential for statistical analysis required for touchdown, and would be much more difficult to put into practice otherwise. We would probably be able to map a surface in the very process of landing.
