All About New Quantum Object

Scientists have created the largest "quantum state" object so far.  The object is a quantum computer that breaks the conventional law of larger physics that one thing cannot occupy two different spaces at the same time.  The machine is being hailed as the first principle component for what could become the first feasible quantum computer.  While not a feasible computer in itself, the "quantum resonator," could replace ones and zeros with far faster computing capabilities that could result in a new generation of incredibly small, energy efficient computers with far more processing power than anything we currently have.

Previously quantum computers were considered too small to be feasible in the quantum realm, due to the fact that scientists naturally assumed it had to happen on the quantum level.  Thanks to a worldwide collaboration of scientists working for years, this new form of computing proves once again that the world





What they've shown here is a mechanical oscillator as a completely new quantum system," Markus Aspelmeyer from the University of Vienna told reporters, "and I personally think it's a really important one"  In addition to the quantum resonator being incredibly fast, it will be able to give a higher output of memory with less energy put into it.  And considerably less at that.

As the system is frozen to one thousandth of one degree above absolute zero, researchers shocked the system with one quantum of electrical energy (known as a quanta) and found that the device oscillated, turning the electrical energy into an equal amount of kinetic vibration energy.  As the device oscillated it contained both one and zero quanta of energy.  Originally, size was the biggest problem with quantum computers, since the quantum effects were never seen larger than a device composed of sixty atoms.  Thanks to this new system, scientists have been able to increase the size of a potential resonator up to around one trillion atoms.

The next technological revolution will come when the superpositions are able to be read using the same circuit that created them, and a sort of memory will be created for quantum based storage systems.  The previous largest device ever created was the "buckyball," but it wasn't pursued as a means of computing due to its incredibly small size and volatile state, and the inability for such a device to record memory.

The new field of computers based on quantum physics will be known as quantum information science.  Eventually, Professor Andrew Cleland said that different systems would be more effective if they used photons rather than vibrations.  While it's difficult to fathom now, a photon based system could in theory even be reversed to make incredibly sensitive detection methods that were previously thought impossible.  Imagine a world where a history of shadows is played out on a single wall based on the tiny photons left behind by residual light effects.  Essentially everything in the universe could be played back visually using such a detection method.
