Quantum superposition

비트가 표현할 수 있는 데이터만큼의 양을 동시에 표현하는 것이 가능

어떤 특정한 물질을 가리키는 말이 아니며, 오히려 추상적인 개념

2개의 양자 상태를 안정적으로 표현할 수 있는 양자 물질이면 어떤 것이든지 큐비트

양자 중첩과 같은 상태를 안정적으로 유지하는 것이 최우선의 과제

Silicon-based qubits take a big leap forward

Over the last few years, the big question in quantum computing has shifted from "can we get this to work?" to "can we get this to scale?" It's no longer news when an algorithm is run on a small quantum computer-we've done that with a number of different technologies.

Qubits Can Be as Safe as Bits, Researchers Show | Quanta Magazine

Over the centuries, we have learned to put information into increasingly durable and useful form, from stone tablets to paper to digital media. Beginning in the 1980s, researchers began theorizing about how to store the information inside a quantum computer, where it is subject to all sorts of atomic-scale errors.
