Key players include Google leaders Kent Walker (President of Global Affairs), Heather Adkins (VP of Security Engineering), and Sophie Schmieg (Senior Cryptography Engineer), alongside NIST, which finalized PQC standards in 2024 and mandates quantum-resistant algorithms for U.S. National Security Systems by 2027, full transition by 2030[2][3][5]. Involved entities encompass Alphabet/Google (migrating Android, Chrome, cloud), security firms like Booz Allen Hamilton, and crypto networks like Bitcoin; adversaries (state actors, cybercriminals) are actively conducting harvest attacks[1][4][6][10].
This builds on decades of warnings since quantum threats were flagged around 2018, accelerated by recent advances in qubits, error correction, and factoring estimates reducing CRQC needs from millions to ~100,000 qubits[5][7][11]. Timeline: NIST PQC standards (2024), Google warning (Feb 7, 2026), new paper (week of Apr 1, 2026), with experts urging immediate preparation amid 3-30 year ranges[1][2][3].
Newsworthy now due to Google's specific 2029 deadline—earlier than prior "decade away" estimates—and confirmation of ongoing harvest attacks, prompting calls for industry-wide PQC adoption amid Bitcoin vulnerability hype on April 1, 2026[1][2][9][11]. A Sheppard Mullin article on April 1 amplified the alarm, tying it to "harvest now" risks and NIST timelines[5].
