Cryptographically relevant quantum computers (CRQCs) capable of breaking current encryption standards will likely emerge between 2030 and 2040, though most experts place the realistic timeline closer to 2035.
This window represents when machines with sufficient qubits and error correction will achieve practical capabilities against RSA and elliptic curve cryptography.
Silicon Quantum Computing was named to Fast Company's 2026 Next Big Things in Tech List, reflecting accelerating progress in the field. The U.S. has emerged as the primary innovation hub with 5 tracked signals of quantum advancement, while China maintains active research programs with 2 tracked signals, creating competitive pressure on timelines.
Governments and enterprises must transition to post quantum cryptography standards immediately. The National Institute of Standards and Technology has already approved replacement algorithms, and migration windows of 5 to 10 years are necessary to protect sensitive data created today against future decryption threats.
