Beginning of Quantum Computing, Computers

Quantum physics has been trying to find a faster solution to current generation computers designed using transistors. Quantum computing would perform similar computing of data, but based on mechanical phenomena, giving computers an exponential boost in speeds.

The basic principle behind quantum computation is simple. Instead of silicon transistors, quantum properties are used to represent data and perform operations on these data. Bits  from current generation computers are replaced with two-state Qubits.

April 18th, 2011 would be considered the first remarkable achievement in the history of quantum computers. For years to come, this day would be recalled for making it possible to transfer a complex set of quantum data in light form. Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.The breakthrough is the first-ever transfer, or teleportation, of a particular complex set of quantum information from one point to another, opening the way for high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via quantum communications networks.

Before this day, the data transmitted was slow and faced data losses.

Teleportation is the phenomena of transferring Quantum information from one location to another using traditional communication media like lasers over Optical fibers using the machine which is called “the teleporter“.

The research is a work of the Australian Defence Force Academy (ADFA), and University of Tokyo researchers.

“One of the limitations of high-speed quantum communication at present is that some detail is lost during the teleportation process. It’s the Star Trek equivalent of beaming the crew down to a planet and having their organs disappear or materialize in the wrong place.

This research is invaluable as for the first time, it enables us to quickly and reliably move quantum information around.

This process means we will be able to move blocks of quantum information around within a computer or across a network, just as we do now with existing computer technologies. The speeds hence achieved would be hundreds of times faster than current generation computers that rely on slow silicon transistors, consuming only the fractions of power.
