A plain-English reference for quantum computing, updated as the field moves.
QubitBasics is a reference site for people who need to understand quantum computing without first learning the underlying physics. The site launched in 2026 with a single overview page and has since grown into a multi-chapter guide covering the hardware, the key algorithms, the cryptography implications, and the practical applications.
Most quantum computing coverage either skips the practical details or buries them under equations. The goal here is the opposite: practical details first, with enough physics to make them make sense.
Each chapter is fact-checked against current academic and industry sources. Hardware claims reference the chip maker's own announcements or peer-reviewed publications. Cryptography claims reference NIST documentation. Algorithm claims reference the original papers or standard textbook treatments.
Claims about future timelines are flagged as estimates rather than facts. The field changes quickly enough that any specific date should be treated as a rough guide.
