Quantum
computing is system computation technology based on the principles of quantum
theory, which explains the nature and behavior of energy and matter on the
quantum (atomic and subatomic) level. This computation use qubit not bit.
quantu coomputation make to solve some
types of mathematical problems on few second. This super computer can try all
possible solutions at the same time, and choose the best.
Entanglement
Entanglement
is a term used in quantum theory to describe the way that particles of
energy/matter can become correlated to predictably interact with each other
regardless of how far apart they are. Particles, such as photons, electrons, or
qubits that have interacted with each other retain a type of connection and can
be entangled with each other in pairs, in the process known as correlation.
Data qubit operations
A
qubit is a quantum bit , the counterpart in quantum computing to the binary
digit or bit of classical computing. Just as a bit is the basic unit of
information in a classical computer, a qubit is the basic unit of information
in a quantum computer . In a quantum computer, a number of elemental particles
such as electrons or photons can be used (in practice, success has also been
achieved with ions), with either their charge or polarization acting as a
representation of 0 and/or 1. Each of these particles is known as a qubit; the
nature and behavior of these particles (as expressed in quantum theory ) form
the basis of quantum computing. The two most relevant aspects of quantum
physics are the principles of superposition and entanglement .
Quantum gates
quantum
gate (or quantum logic gate) is a basic quantum circuit operating on a small
number of qubits. They are the building blocks of quantum circuits, like
classical logic gates are for conventional digital circuits. Unlike many
classical logic gates, quantum logic gates are reversible. However, classical
computing can be performed using only reversible gates. For example, the
reversible Toffoli gate can implement all Boolean functions. This gate has a
direct quantum equivalent, showing that quantum circuits can perform all
operations performed by classical circuits.
Shors algorithm
Shors
algorithm named after the mathematician Peter Shor, is a quantum algorithm .
This algorithm runs on a quantum
computer and useful for integer factorization. Shors algorithm was formulated
in 1994. Essence of this algorithm is how to resolve the factorization of the number
interger or a large integers.
