Quantum Internet Proves Real-World Feasibility Across 38 Miles of Fiber

NIST researchers transmitted polarization-entangled photons across 62 kilometers (38.5 miles) of existing, above-ground fiber in real-world conditions, maintaining entanglement despite environmental noise by using a laser reference to calibrate corrections. The setup operated with 200–1,500 entangled photons per second, showing feasibility for practical quantum networks and potential uses in quantum-secure communications and distributed telescopes, though faster hardware and better software are needed for a full quantum internet.

NIST-SRI Launch Center to Accelerate Quantum Manufacturing

NIST and SRI International are creating the Quantum Manufacturing Engineering Center (QMEC) with an initial $20 million to accelerate the scalable manufacture of high‑performance quantum components and systems, address manufacturing barriers, and strengthen the U.S. quantum industry through public‑private collaboration and connections to the Quantum Economic Development Consortium (QED-C).

US Sets Firm Deadlines for Government’s Post-Quantum Crypto Shift

The White House is fast-tracking the U.S. shift to post‑quantum cryptography with a new executive order that requires agencies to appoint PQC leads within 30 days, move high‑value assets to quantum‑resistant keys by end‑2030 and adopt PQC digital signatures by end‑2031. NIST will launch a PQC migration pilot within 180 days, and OMB must issue new guidance within 90 days, while procurement reforms and centralized support are also mandated. While the move addresses long‑term security against quantum threats, experts warn funding gaps, data‑lifecycle concerns, and the scale of cloud, vendor, and contractor transitions present major challenges ahead.

US tightens path to quantum-proof crypto with 2030–2031 deadlines

The White House issued an executive order to speed up the adoption of quantum-resistant cryptography, requiring high-value assets to switch to PQC key establishment by December 31, 2030 and to PQC digital signatures by December 31, 2031. The move shortens timelines by about 4–5 years and establishes government-wide coordination, new procurement rules for contractors, and guidance on a cryptographic bill of materials, all in response to advancing quantum computing and the risk of future decryption of stored data. The plan relies on collaboration with NIST, DoD, DHS, and other agencies, and marks a shift from earlier 2035–2033 targets for many systems.

NIST: Surfside Collapse Fueled by Early Structural Failures and Code Gaps

The final NIST report says the 2021 Surfside Champlain Towers South collapse began weeks earlier, with failing garage connections and an inadequately designed pool deck, worsened by later alterations that stressed an already weak structure. Noncompliant design with code standards, plus corrosion and leaks, left margins too narrow and set the stage for the disaster that killed 98 and spurred condo-reserve reforms.

NIST Finds Surfside Collapse Traced to Weeks of Distress Before Fall

A final NIST report says the Surfside Champlain Towers South collapse began weeks before it fell, when two garage-to-pool-deck connections started failing around early June. The building’s design did not meet code, later alterations and long‑term corrosion further reduced margins against failure, contributing to a slow, deadly collapse that killed 98 people and spurred settlements and Florida maintenance-law changes for condo associations.

NIST pinpoints early column failures weeks before Surfside collapse

Federal investigators found that Champlain Towers South’s collapse was preceded by a three-week period of progressive failures: cracks grew as the pool-deck garage columns failed and weight was redistributed to weaker adjacent slabs, ultimately causing part of the 12‑story building to fall in June 2021, killing 98 people.

NIST flags weeks of warning signs before Florida condo collapse

A NIST investigation into the Surfside, Florida condo collapse found warning signs weeks earlier, including a long crack in a planter wall on the pool deck, water leaks in the parking garage, and corroded reinforcing steel, with the destruction unfolding as sections failed in sequence; lawmakers later enacted laws to bolster condo reserves and maintenance requirements.

US Commits to Quantum-Resistant Cryptography Across Federal Agencies

The White House issues an executive order mandating a federal shift to post-quantum cryptography to protect national security against quantum threats. It assigns PQC migration leads, requires HVAs and high-impact systems to migrate to PQC for key establishment by 2030 and for digital signatures by 2031, and launches a NIST pilot by 2027. The plan emphasizes cross‑agency coordination (OMB, National Cyber Director, CISA, NSA), updated procurement rules, a cryptographic bill of materials, and international engagement to accelerate PQC adoption across federal agencies and critical infrastructure.

NIST Expands Cannabis Spectral Library With 41 New Cannabinoid Signatures

The National Institute of Standards and Technology added 41 new cannabinoid spectra to its mass-spectral library (Standard Reference Database 1A), increasing cannabis-related entries to 121. The update emphasizes rare side-chain homologs and derivatives to improve identification of uncommon cannabis compounds for forensics, biomedical research, food science and environmental testing.

Envelope Trick Highlights Subtle Biases in Measuring Gravity’s Constant

An NIST redo of the 2007 BIPM measurement of the gravitational constant G, using a blinded-envelope approach to avoid bias, yields a result close to the French value but with a 0.0235% discrepancy after adjustments; Schlamminger also identifies a newly observed spurious torque driven by temperature gradients and residual gas in the vacuum, suggesting unaccounted biases in the uncertainty budget and underscoring the ongoing challenge of precisely measuring G and the importance of reproducibility.

NIST's decade-long hunt keeps Big G from settling on a single precise value

NIST researchers spent a decade replicating a Cavendish-style experiment to measure Big G, testing copper and sapphire masses with an electrostatic twist, and report G = 6.67387×10^-11 m^3/kg/s^2—about 0.0235% lower than the BIPM value. The result adds another data point but does not resolve the long-standing discrepancy, highlighting gravity’s weakness and Earth’s background noise as ongoing challenges — while advancing precision instrumentation and metrology.

Big G Remains Elusive as a Decade of Gravity Tests Clash with CODATA

After a decade of cross‑Atlantic replication led by NIST, the new measurement of the gravitational constant G disagrees with both the 2013 BIPM result and CODATA’s current value, highlighting that Big G is still the least precisely known fundamental constant and that the true value remains unresolved despite improved methods (including a blinded measurement to reduce bias).

A Decade-Long Hunt Keeps Gravity’s Constant Unsettled

A decade-long effort by NIST to measure the universal gravitational constant G, using a torsion-balance setup and multiple test masses, produced a value of 6.67387×10^-11 m^3/(kg·s^2) that is 0.0235% lower than the BIPM's result, sustaining a small but persistent discrepancy among precision measurements. An unusual blinding step— a colleague secretly altered some data to hide the true result until the envelope reveal—meant Schlamminger only learned the outcome at the end. Although the difference is too small to affect everyday life, it keeps G as an open question and underscores the need for further, careful measurements.

NIST narrows vulnerability scoring to high-risk issues as submissions surge

NIST will stop enriching and rating severities for low-priority vulnerabilities in the NVD due to a 263% rise in submissions; only CVEs meeting KEV criteria, affecting U.S. federal software, or involving critical software will receive added details, while all CVEs stay in the database and others are labeled Not Scheduled; enrichment requests remain possible via [email protected].
