Quantum Computation or quantum computer is a tool for the calculation, which uses direct calculation of quantum mechanical phenomena such as superposition and the computation and entanglement to perform operations on data. Quantum computers are different from traditional computers based on transistors. Differences with a quantum computer on a classical computer is a classical computer has a memory made up of bits, where each bit represents either one or zero. While a quantum computer qubits maintain order. A single qubit can represent a one, a zero, or, crucially. The basic principle of quantum computers is that the quantum properties of particles can be used to represent data and data structures, and that quantum mechanics can be used to perform operations with this data. In this case the system to develop a quantum computer needed a new logic in accordance with the principles of quantum.
Entanglement
“Entanglement is the essence of quantum computing because it is interwoven
quality associated with a lot more information in quantum bits than the bits of
classical computing”, said Andrew Berkley, one of the researchers. The latest
findings bring the path to quantum computers, and indicates that the Josephson
junction could eventually be used to build a super computer.
Operation
Data Qubit
Quantum information science begins with the fundamental resources generalize
classical bits of information into quantum bits, or qubits. As bits are ideal
objects are abstracted from the principles of classical physics, qubits are
quantum objects are abstracted ideal of the principles of quantum mechanics.
Can be represented by a bit – magnetic region on the disc, the voltage on the
circuit, or sign graphite pencil on paper made. Functioning of classical
physical statuses, as bits do not depend on the details of how they are
realized. Similarly, the attributes qubit is independent of specific physical
representation of the atomic nucleus as a centrifuge or say, the polarization
of a photon of light.
Illustrated
by the status bits, 0 or 1. Similarly, the qubit is described by its quantum
status. Two potential for qubit quantum state is equivalent to the classical
bits 0 and 1. But in quantum mechanics, any object that has two different
statuses certainly has a series of other potential state, called superposition,
which led up to the status of second -degree manifold. Qubit statuses are
allowed exactly is all the status that must be achieved, in principle, by the
classical bits are transplanted into the quantum world. Status – qubit state is
equivalent to the points on the surface of the ball, where 0 and 1 as the south
and north poles. Continuum between 0 and 1 status fostered many outstanding
attributes of quantum information.
Quantum
Gates
In
quantum computers and quantum circuit model of computation in particular, a
quantum logic gates or quantum gates are the basic operations of quantum
circuits on a small number of qubits. They are the building blocks of quantum
circuits, like classical logic gates to a conventional digital circuits.
Shor
Algorithm
Shor’s algorithm is a further example of the basic paradigm (how much
computational time required to find a factor of n-bit integers?), But this
algorithm seems isolated from most of the other findings of quantum information
science. At first glance, it is just as ingenious programming tricks with
little fundamental significance. Appearances are deceptive; researchers have
shown that Shor’s algorithm can be interpreted as an example of a procedure to
assign the energy levels of quantum systems, a process that is fundamental. As
time goes on and we charge more on the map, should be so easy to understand the
principles underlying Shor’s algorithm and other quantum algorithms and, we
hope, develop new algorithms.
