Google’s new chip, Willow, represents a significant step towards building a scalable quantum computer. It solves complex problems in minutes, outpacing classical supercomputers drastically.
Seth Lloyd illustrated the distinction between classical and quantum computers by comparing them to musical compositions, stating that classical processing is like a Gregorian chant—a single line of computation—while quantum processing is akin to a symphony.
The core difference in computing arises from bits: classical bits are binary states, while qubits can exist in multiple states simultaneously due to quantum superposition and entanglement, enabling more complex calculations.
One of quantum computing's primary challenges is the fragility of qubits, which are highly sensitive to their environments, complicating the stability and practicality of building robust quantum systems.
