Google unveiled Willow, its latest quantum
chip, marking a milestone in the development of quantum computing.
About Quantum Chips
- While regular chips use ‘bits’ (0 or 1) to process information, quantum chips use ‘qubits’.
- A classical bit can only exist in either a 0 position or a 1 position. Qubits, however, can also occupy superposition, which represents O, 1, and all the positions in-between taken at once, for a total of three separate positions.
- While qubits can encode three separate positions, they are still used to convey information through a binary system.
- Also, two quantum bits can be correlated with each other so that the state of one quantum bit is dependent on the state of another quantum bit (Entanglement).
- Like a classical computer, a quantum computer is also a host of physical operations called quantum gates that change the states of qubits to perform calculations.
- In a classical computer the information flowing in and out of bits is controlled and manipulated by physical operations called gate operations. For example, an ‘AND’ gate accepts two inputs, each either 0 or 1, and outputs 1 if both inputs are 1 and 0 for any other combination of inputs.
