First Commercial Quantum Computing System from IBM

IBM debuts the Q System One, an integrated quantum computing system made for commercial and research use, the first of its kind in the world.

The system can be used to predict events that are almost impossible for classical computing, but which quantum computing is uniquely adept at solving. For example, predict financial events, optimize logistic problems.

Quantum mechanics describe our world as entangled waves in time and space (or a set of vectors where time and space dimensions are just mathematical presentations), instead of collection of small particles moving in space. This means that, because of this property of measurement in quantum mechanics, our universe is inherently a non-local, and everything seems connected. In another word, any quantum mechanics interaction has the whole universe considered, that's why it is simpler to predict financial events for quantum mechanics -- complexity and considering the influence of outside world is not a problem at all in quantum mechanics!

Here is an example program I ran on a 3 qubits IBM Q quantum computer. It demonstrate the quantum entanglement.

Entanglement is the weirdest of all quantum phenomena. Two or more quantum objects are entangled when, despite being too far apart to influence one another, they behave in ways that are 1) individually random, but also 2) too strongly correlated to be explained by supposing that each object is independent from the other. As the basic phenomena of physics, entanglement is everywhere. Some particles or waves in your body and my body might be in entangled states now, they go hand in hand. It is mind blow -- when your brain managed to flip one wave in your body, it flipped the other half in mine too, even though I never know you. Yes, no matter who we are, our thought litterally changed the world.

See the demo result? We only got 11 and 00 states, there is no 10 and 01 states. The 2 particles always agree with each other. In theory, the two qubits always agree, even you move one of them zillions of miles away.
