New techniques discovered to verify Quantum Chips are computing correctly

In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can’t. Quantum chips perform computations using quantum bits, called “qubits,” that can represent the two states corresponding to classic binary bits—a zero or one—or a “quantum superposition” of both states simultaneously. Quantum computers use the superposition state which solves problems that are practically impossible to classical Computers. Full-scale quantum computers require millions of qubits which is not yet feasible. Researchers has started developing “Noisy Intermediate Scale Quantum” (NISQ) chips, which contain around 50 to 100 qubits. This is not enough…
