What is quantum supremacy?

Quantum supremacy, or “quantum advantage”, is the potential ability of quantum computing devices to solve problems that classical computers cannot. According to experts, we are nearing “quantum supremacy”— a nebulous frontier where quantum computers begin to do things beyond the ability of classical machines. Researchers from Google are now testing a quantum computer with 72 quantum bits, or qubits — a big step up from the company’s previous nine-qubit chip. In January 2018, Intel passed a milestone to build quantum-computing systems. The technology giant has also unveiled a superconducting quantum test chip with 49 qubits, or enough qubits to possibly enable quantum computing.
