Are the qubits physical or logical? Is there a paper, and who checked it? A reader can judge a quantum computing announcement with seven questions, each shown here with a 2026 case and the document that answers it.
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.
Certificate authorities, the DNS root's operator, and firmware signers generate keys under quorum, script, and witness. ML-DSA keys fit that pattern. LMS and XMSS keys cannot be backed up the classical way, since reusing a one-time key allows forgery.
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.
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.
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.
The non-binding poll asks only whether to start research. StarkWare argues that a layer 2 can be no more quantum-safe than Ethereum, which targets December 2029 for its own migration.
One of the largest bitcoin custodians asked for at least one scheme suited to multi-party signing. Its own security chief has said Coinbase needs two to three more years of research to build that capability.
