- What is quantum computing 3
- quantum computing 4 Quantum computing is the study of a non-classical model of computation. Whereas a classical computer encodes data into fundamental units called bits, where each bit represents either a one or a zero. A quantum computer encodes data into bits that can represent a one, a zero, or some combination. QUANTUM COMPUTING perform calculations based on the probability of an object's state before it is measured - instead of just 1s or 0s - which means they have the potential to process exponentially more data compared to classical computers.

- Working of quantum computing In quantum computing, operations instead use the quantum state of an object to produce what's known as a qubit. These states are the undefined properties of an object before they've been detected, such as the spin of an electron or the polarisation of a photon. Rather than having a clear position, unmeasured quantum states occur in a mixed 'superposition', not unlike a coin spinning through the air before it lands in your hand. These superpositions can be entangled with those of other objects, meaning their final outcomes will be mathematically related even if we don't know yet what they are. The complex mathematics behind these unsettled states of entangled 'spinning coins' can be plugged into special algorithms to make short work of problems that would take a classical computer a long time to work out... if they could ever calculate them at all. Such algorithms would be useful in solving complex mathematical problems, producing hard-to-break security codes, or predicting multiple particle interactions in chemical reactions 6

- Type of quantum computing One way quantum computing:-contains highly entangeled qubits. Adiabatic quantum computer:-execuit alogarithms to through transformation of hamiltons whose ground state contais one or more solution. Topological quantum computer:-break down problem in a 2d topological space of anyons to crave for solution. 8
- advantage Could process massive amount of complex data. Ability to solve scientific and commercial problem. Process data in much faster speed. Capability to convey more accurate answer. More can be computed in less time. 9
- disadvantage Hard to control quantum particles. Loats of heat. Expensive Difficult to build Not suitable for word processing and email. 10
- application Simullating Factorization Cryptography Improved error correction and error detection. Molicular simulation 11
- conclusion quantum computing is very promising. quantum mechanic is hard to impliment. quantum can’t be solved np-complete problems. quantu provide efficient environment for communication 12
