What is Quantum Computing and How it works?
Quantum computers are much more powerful than supercomputers. Large tech companies like IBM, Google, and Rigetti use them. Quantum computer ‘Sycamore’ was achieved by Google in 2019 with its Quantum Supremacy. Sycamore claims to perform calculations in 200 seconds which is usually done by supercomputers in 10,000 years. It is a 54-qubit computer. Special conditions with temperature as low as zero are required to keep such computers. Quantum Physics Quantum computing falls under Quantum Physics. Superposition and Qubits (Quantum Bits) are the two components where Quantum computing’s heart and soul resides. What are these? Take an example of a coin and spin it in the air. The outcome of the coin on reaching the ground can either be head or tail. This cannot be exactly said until it touches the ground. However, when the coin is in the air it is head and tail both at the same time (Qubit). This condition can be called Superposition. How it works Bits are combinations of 0’s and 1’s (ne
