What is Quantum Computing? Top 18 Quantum Computing Companies
The field of quantum computing was initiated in 1980’s and Quantum computing is the biggest breakthrough in computer technology since the invention of the microprocessor. A classical computer has a memory made up of bits.Each bit is either off or on, designated by either a zero or a one.
Digital computers require data to be encoded into binary digits called bits, and each of which is always in one of two definite states either zero or one. Quantum computers are different from digital electronic computers based on transistors. These are made out of quantum particles that can be designated by a zero, one, or some kind of state in between. Quantum computation uses quantum bits called qubits. This can be in superpositions of states and hence qbits can have both values at the same time.
Quantum computer maintains a sequence of qubits and quantum Turing machine is a theoretical model of such a computer, which is also known as the universal quantum computer. In simple terms this means that quantum computers have the potential to be much more faster and many times more powerful than today’s computers.
The development of actual quantum computers is still in its infancy, but experiments have been carried out in which quantum computational operations were executed on a very small number of quantum bits. Many national governments and military agencies are funding quantum computing research in an effort to develop quantum computers for civilian, business, trade, environmental and national security purposes, such as cryptanalysis.
Quantum Computing Models
Quantum computing models, are distinguished by the basic elements in which the computation is decomposed. The four main models of practical importance are Quantum gate array, One-way quantum computer, Adiabatic quantum computer and Topological quantum computer.
In Quantum gate array computation is decomposed into sequence of few qubit quantum gates. The computation is decomposed into sequence of one-qubit measurements applied to a highly entangled initial state or cluster state in One-way quantum computer.In Adiabatic quantum computer, the computation is based on Quantum annealing and in Topological quantum computer the computation is decomposed into the braiding of anyons in a 2D lattice.
Technical Challenges in Quantum Computing
Technical Challenges in Quantum Computing are in creating systems that can run lots of qubits, minimizing the number of qubits needed to do any algorithm or calculation, and in developing advanced error correction capabilities.
