Quick answer This tracker lists dated quantum computing milestones and the main companies, newest first, with a primary source for every row. Roadmap rows are plans, not delivered machines. It contains no prices and no predictions.
Milestones Date What happened Who Type Source 2025-06-10 IBM publishes a roadmap targeting IBM Quantum Starling by 2029: a fault tolerant machine running 100 million gates on 200 logical qubits. IBM Roadmap (a plan, not delivered) IBM Quantum blog 2025-05 Google researchers estimate 2048 bit RSA could be broken by under 1 million noisy qubits in about a week, a 20 fold drop from their 2019 estimate. Google Quantum AI Resource estimate Google Security Blog 2024-12-09 Google announces the 105 qubit Willow chip and error correction where errors fall as the code grows ('below threshold'). Google Quantum AI Hardware and error correction result Google blog 2024-08-13 NIST finalises the first three post-quantum cryptography standards: FIPS 203, 204 and 205. NIST Standard NIST 2019-10-23 Google reports a random circuit sampling experiment on its 53 qubit Sycamore chip and claims quantum supremacy. The claim was later disputed by classical computing researchers. Google Experiment (disputed) Nature 1996 Lov Grover publishes a quantum search algorithm with a quadratic speedup over classical search. Lov Grover Algorithm arXiv:quant-ph/9605043 1994 Peter Shor shows a quantum computer could factor integers and compute discrete logarithms efficiently, the basis of the threat to RSA and elliptic curve cryptography. Peter Shor Algorithm arXiv:quant-ph/9508027
