Alice & Bob's new count is about a quarter of its 2024 estimate. The authors assumed cat qubits that keep their value for about 100 years. Researchers have measured up to 22 seconds under full control.
Most of the 500 respondents said today's PKI will need to change to a great extent for post-quantum cryptography. Four percent said certificate management is fully automated, ahead of a 100-day cap on public TLS certificates issued from March 2027.
NIST dropped the draft's two-tier schedule and now deprecates RSA-3072, P-256, and Ed25519 after 2030, as it does RSA-2048. The agency also kept a path to FIPS 140 validation for hybrid key exchange.
The Sydney company said it cut its February estimate by about an order of magnitude in qubit-time with its Pinnacle 1.2 update. It has not published the circuits, the decoder, or the hardware behind its decoding speed.
Israel's quantum sector grew from about five companies in 2019 to more than 20 in 2025 and has raised more than $1 billion in private capital. A national committee recommended a dedicated governance body for the next phase.
Intel plans to pair Classiq's circuit-synthesis software with its own spin-qubit manufacturing. The company does not yet sell a quantum computer. Its best-known chip, released to research labs in 2023, has 12 qubits.
Chrome blocked the six compromised TLS intermediates within two hours of the researcher's report. Linux distributions, language runtimes, and devices that ship their own root lists were still being patched four days later.
Quantinuum's team cut logical errors about 12-fold with each step up in code distance on the 98-qubit trapped-ion machine, for one stored logical qubit. The preprint has not been peer reviewed.
An open-weight model running on IBM's GPUs found a 52-fold faster design for about $26 in inference. The speedups are synthesis-tool estimates for an FPGA decoder, from a single run of each configuration.
MITRE placed no category on its top rung, reserved for products that run post-quantum functions through a FIPS 140-3 validated module. In public vendor evidence gathered in July, it found no post-quantum hardware TPM on sale.
