INTRODUCTION :- One of the major areas of research and development to get most hype in recent time is QUANTUM COMPUTING. The holy grail of the computing revolution that is supposed to be the next big advancement. It is fundamentally different than classical computing and help the technology to solve many problems that are intractable with current technology. WORKING :- Quantum computing uses quantum mechanical phenomenon such as superposition and entanglement to perform computation. Normal computer uses binary digits (bits) i,e. 1 & 0 whereas Quantum computer uses quantum bits or qubits. Quantum computing takes advantage of the strange ability of sub - atomic particle to exist in more than one state at any time . This superposition of state allow quantum computer to be faster and more efficient. FUTURE USE :- Weather & climate: More accurate long term climate assessment to predict the effect of climate change. Pe...
