Quantum Information Theory

Quantum Information Theory is the expansion of combining classical physics with digital information theory based on modern mathematics. It shows a new paradigm which includes calculation, communication, and statistical physics.

Quantum Algorithms

Computation theory based on the Turing machine and classification of computational complexity are faced with a completely new extension because of the possibility of a quantum computer.

A quantum computer contains many useful algorithms by utilizing quantum parallelism using Quantum Fourier Transformation. These algorithms include searching quantum databases, and solving quantum many-body problems.

Quantum Entanglement

It consists of the study of fundamental secrets of quantum physics such as non-locality, efficiency of many quantum algorithms and a variety of quantum communication applications. Experiments using quantum optics implement the theory of quantum entanglement are studied in great detail..

Quantum Computer

There are many research results based on the realization, physical conditions, and quantum decoherence aspects of making a quantum computer. In the majority of approaches we see such research as based on linear and nonlinear quantum optics and atom-molecule experiments.

Quantum Cryptography

Even though in the light of recent advances in quantum information applied to quantum computing, current digital cryptography cannot guarantee perfect security, we find that quantum information provides us with a new type of security method.

After the BB84 and B92 protocols, there are many outcomes in quantum cryptography using quantum entanglement, quantum repeaters to send unlimited transportation of quantum states by quantum teleportation and quantum optics. Additionally we have seen that there have been improvements in the principles of quantum cryptography and security proof.

Quantum Teleportation

It is a way of transportation of information utilizing the non-locality of quantum physics without any continuous equation of motion like in classical mechanics.

Quantum Error Correction

There is a way to correct crucial errors from quantum information processing in a similar way that digital error correction makes sure of the success of digital information processing. These are the studies of optimizing quantum error correction.

Quantum Imaging

There are the studies of quantum imaging such as quantum holography and quantum ellipsometries which use the non-locality of quantum entanglement.
