Quantum Computing: Difference vs Normal Computers

[QUOTE="Abhishek Sethi, post: 5510750, member: 594138"] Hi, In any form of computation, there is a physical construct behind it. The fundamental difference between quantum computing and classical computing is due to the different structure used. For example, in classical computing, a bit can be represented by a transistor. Physical quantities(like electric field, current density etc) associated with the transistor determine the value of this bit. So, the value of the bit represents some physical property. The value of the bit can be changed by manipulating the system physically, maybe by applying an external magnetic field. So, the operator or "a logic gate" represents a physical manipulation. The limitations and the capabilities of the physical construct is what determines the limitations and capabilities of the computation. You would need to understand QM in order to understand the representation of a bit(qubit) and the operations that can be used(operators). This is what makes quantum computing different from classical computing. I can point some features of QM that makes QC what it is, 1) Principle of superposition of multiple wave functions 2) Correlation between multiple bits(qubits) or quantum entanglement Some popular advantages in QC over CC, 1) Grovers search algorithm(faster than binary search algorithm) 2) Shors Algorithm to find prime factors(works great under some constraints) Correct me if I am wrong somewhere. Hope it helps. [/QUOTE]
