Quantum computing (as of 2020)

began in 1980s
operates on principles of quantum physics rather than the limitations of circuits and electricity
it could one day achieve things that classical computing can’t
it has the potential to unravel [rozmotať] decades of work put into crypto algorithms and standards we use today
everything that’s encrypted with today’s PK crypto can be decrypted with tomorrow’s quantum computers
it might take 10 to 15 years

Bottom line: we need to work on post-quantum security.
