- Quantum computers use qubits that can exist in superpositions and become entangled with one another, rather than classical bits.
- The most advanced quantum computers currently have hundreds of interconnected qubits and make an error roughly once in every thousand operations.
- Scientists hope for applications in molecular and materials simulations, complex optimization problems and analysis of encrypted data, but most remain years or decades away.
- The article says a quantum computer running Shor’s code-breaking algorithm might require millions of qubits operating error-free indefinitely, while today’s systems mainly serve research and testing purposes.
"It seems to me we're just on the threshold of quantum systems doing genuinely new simulations that we can't do classically," says Glancy. "It might inspire a revolution in physics. In my opinion that is a good reason to build a quantum computer."— Scott Glancy, a physicist at NIST, quoted in the NIST article Quantum Computing Explained
