Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet.
The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.
“The bigger you make the certificate, the slower the handshake and the more people you leave behind,” said Bas Westerbaan, principal research engineer at Cloudflare, which is partnering with Google on the transition. “Our problem is we don’t want to leave people behind in this transition.” Speaking to Ars, he said that people will likely disable the new encryption if it slows their browsing. He added that the massive size increase can also degrade “middle boxes,” which sit between browsers and the final site.

DENVER—The US Air Force's new Sentinel intercontinental ballistic missile is on track for its first test flight next year, military officials reaffirmed this week.
But no one is ready to say when hundreds of new missile silos, dug from the windswept Great Plains, will be finished, how much they cost, or, for that matter, how many nuclear warheads each Sentinel missile could actually carry.
The LGM-35A Sentinel will replace the Air Force's Minuteman III fleet, in service since 1970, with the first of the new missiles due to become operational in the early 2030s. But it will take longer than that to build and activate the full complement of Sentinel missiles and the 450 hardened underground silos to house them.

Netflix has dropped out of the bidding war for Warner Bros. Discovery (WBD), making Paramount Skydance the expected owner of WBD. A Paramount-WBD merger remains subject to regulatory approval, but it’s likely that we will see a Paramount-Skydance-Warner-Bros.-Discovery media giant.
Such a conglomerate would unite two legacy media companies that have struggled with profitability for years and have strongly invested in streaming and cable.
With Paramount inching closer to WBD ownership, let’s look at what the union implies for streaming and cable.

Despite the headline, this isn't really a story about superconductivity—at least not the superconductivity that people care about, the stuff that doesn't require exotic refrigeration to work. Instead, it's a story about how superconductivity can be used as a test of some of the weirder consequences of quantum mechanics, one that involves non-existent particles of light that still act as if they exist.
Researchers have found a way to get these virtual photons to influence the behavior of a superconductor, ultimately making it worse. That may, in the end, tell us something useful about superconductivity, but it'll probably take a little while.
The story starts with quantum field theory, which is incredibly complex, but the simplified version is that even empty space is filled with fields that could govern the interactions of any quantum objects in or near that space. You can think of different particles as energetic excitements of these fields—so a photon is simply an energetic state of the quantum field.

The US military mistakenly shot down a Customs and Border Protection (CBP) drone near the Mexican border in a strike that reportedly used a laser-based anti-drone system. The CBP uses drones to track people crossing the border.
"Congressional aides told Reuters the Pentagon used the high-energy laser system to shoot down a Customs and Border Protection drone near the Mexican border, in an area that often has incursions from Mexican drones used by drug cartels," Reuters reported last night.
The FAA closed some airspace along the border with Mexico in Fort Hancock, Texas, on Thursday with a notice announcing temporary flight restrictions for special security reasons. The restrictions are in place until June 24 but could be lifted earlier. There are conflicting reports on which day the strike happened, with The New York Times reporting that the strike occurred Thursday and Bloomberg writing that the Federal Aviation Administration (FAA) “was notified Wednesday after the event occurred.”

We haven't had a new film from Gore Verbinski for nine years. But the director who brought us the first three Pirates of the Caribbean movies, the nightmare-inducing horror of The Ring (2002), and the Oscar-winning hijinks of Rango (2011) is back in peak form with Good Luck, Have Fun, Don't Die. It's a darkly satirical, inventive, and hugely entertaining time-loop adventure that also serves as a cautionary tale about our widespread online technology addiction.
(Some spoilers below but no major reveals.)
Sam Rockwell stars as an otherwise unnamed man who shows up at a Norms diner in Los Angeles looking like a homeless person but claiming to be a time traveler from an apocalyptic future. He’s there to recruit the locals into his war against a rogue AI, although the diner patrons are understandably dubious about his sanity. (“I come from a nightmare apocalypse,” he assures the crowd about his grubby appearance. “This is the height of f*@ing fashion!”)
