چکیده
This paper gives a glimpse of basic quantum computing concepts, which is an active area of research in today's world. The discussion starts with difference between a quantum computer and a classical one at the bit level, register level, logic gates level and at circuit level. Then, some of the important quantum phenomena such as quantum entanglement and quantum interference are discussed. After that, the basic principles of quantum computing are discussed, and the phenomenon of quantum parallelism is discussed, which explains why a quantum computer is exponentially faster than classical computers. Finally, some of the basic quantum algorithms vis-àvis Deutsch's algorithm and Deutsch-Jozsa algorithm are explained, and some of the potentials and hurdles in building a quantum computer are listed. Keywords— quantum circuit, quantum gate, quantum interference, quantum parallelism, qubit, Deutsch's algorithm, Deutsch-Jozsa algorithm

متن کاملOptimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits
There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....
