Researchers at TU Delft in the Netherlands have managed to bring two electrons, three meters from each other, into a quantum- entangled state. This result marks a major step towards realizing a quantum network that can be used to connect future quantum computers and to send information in a completely secure way by means of “teleportation”. The results have been published online on April 24 in Nature .
Entanglement is arguably the most intriguing consequence of the laws of quantum mechanics. When two particles become entangled, their identities merge: their collective state is precisely determined but the individual identity of each of the particles has disappeared. The entangled particles behave as one, even when separated by a large distance. Einstein doubted this prediction, which he called “spooky action at a distance”, but experiments have proven its existance.
Entangled states are interesting for computers as they allow a huge number of calculations to be carried out simultaneously. A quantum computer with 400 basic units (“quantum bits”) could, for example, already process more bits of information simultaneously than there are atoms in the universe. In recent years, scientists have succeeded in entangling quantum bits within a single chip. Now, for the first time, this has been successfully achieved with quantum bits on different chips.
What could we do with a 400 qbit quantum computer?
At 100 qubits a single quantum computer processor would, theoretically, be more powerful than all the supercomputers on the planet combined. We may be closer to that milestone than you think and the world isn’t ready.
Quantum computers are spooky devices that don’t follow the normal rules of physics. Instead of bits, like classical computers, they use qubits.
One of the biggest barriers to advancing quantum computer hardware is dealing with all the noise generated by those qubits, they’re hyperactive compared to regular bits, so it’s hard to figure out what’s going on with them.
But a series of advancements in error-correction and noise-supression have recently paved the way forward. And, if history is any indicator, we can expect a usable 100 qubit processor as early as this year.
… As far as doom and gloom goes, the people screaming about killer robots might have it wrong. The Washington Post reports “quantum computers may be more of an imminent threat than AI.”
Quantum brute-force would, theoretically, make classical encryption obsolete.

My odd suspicion is that a working 400 q-bit computer could read minds and that such an advanced system does exist. It sounds like science fiction, and I have no inside information on this, but given enough data on someone, I think a very advanced computer could accurately predict, by modeling a person’s “self” through use of the person’s published thoughts and past behaviors, what that “self” would think and do given new experiences in his/her environment. It would seem like magic alien or god-like technology, but could be accomplished with code and simple data collection (AI “groking” of massive amounts of data).
There could also be positive benefits to the use of this technology, like helping someone self-actualize, to have a more fulfilling life, and to reach their higher life goals by adjusting some behaviors. Once a quantum AI can predict thoughts, it can obviously also start to influence thoughts. At this point, you are at the mercy of the people or AIs running the programs. Be cool to them and they may help you.
Even if this is not yet true, you might try, in your life, believing that it is, that you are being positively adjusted by a beneficial AI. Let the intelligence guide your life and see where that leads. Watch for clues, such as opportunities you are given to help others, do the right thing and see where the program take you. It’s one way to live an interesting life.
