CBP Wants AI-Powered ‘Quantum Sensors’ for Finding Fentanyl in Cars


United States Customs and Border Protection is paying General Dynamics to create a prototype of “quantum sensors” alongside a “database with artificial intelligence” designed “to detect illicit objects and substances (such as fentanyl) in vehicles, containers, and other devices,” according to a contract justification published in a federal register last week.

“This database and sensor project will integrate advanced quantum and classical sensing technologies with Artificial Intelligence and ultimately deploy proven concepts and end products anywhere in the CBP environment,” the justification document reads. “Under this requirement, CBP will take additional steps to enhance its ability to detect, and thus, significantly reduce the harms of illicit contraband entering the United States of America, thus bolstering national security.”

The document redacts the name of the company developing the prototype; however, contract details included in the federal register entry reveal that the justification is for a $2.4 million General Dynamics contract that has been public since December 2025.

CBP and General Dynamics did not respond to WIRED’s requests for comment.

CBP’s request for a prototype of “quantum sensors” with an AI database—which comes amid a widespread push within the Department of Homeland Security (DHS) “to support the adoption and scaling of AI technologies,” according to a strategy memorandum published last year—involves a real and growing area of scientific and technological research.

Last week’s justification does not get into detail about which methods its “quantum sensors” would use or what information the AI database would store and analyze. However, it does provide hints about detection methods the agency has considered.

The document claims that CBP conducted market research from April through October of 2025. In July, CBP published an information request seeking a vendor for exactly 35 handheld “Gemini” analyzers, sold by Thermo Fisher Scientific, which are designed to identify unknown chemicals and narcotics.

DHS has also tested the Gemini in previous years, according to reports published in 2021 and 2023. The July request—which notes that the devices would be used to identify substances like fentanyl, ketamine, cocaine, methamphetamine, diazepam, and MDMA—makes no mention of artificial intelligence or a database.

“The detection equipment will be used by CBP Officers in non-intrusive testing to detect a wide range of narcotics, controlled substances, unknown substances, and general organic materials,” the request reads, noting that the agency “continues to seize an increasing number of opioids at the nation’s borders.”

The July request for information claims that the Gemini analyzers use “Fourier Transform Infrared Spectroscopy (FTIR),” which measures how much infrared light a sample absorbs, and “Raman spectroscopy,” which measures how light scatters off the surface of a sample when a laser is directed at it.

Last week’s contract justification says that the agency found an American company that creates a “handheld analyzer” for identifying dangerous chemicals but claimed it “cannot detect fentanyl.” It’s unclear whether this was referring to Gemini or one of the more than 10 other devices DHS tested in 2021 and 2023. But when reached for comment, Thermo Fisher Scientific said that its Gemini analyzers “are designed to detect fentanyl.”

It’s also unclear whether the General Dynamics prototype may use FTIR or Raman spectroscopy. But a 2024 working paper about a laboratory-based fentanyl-detection method (unrelated to CBP, General Dynamics, or Thermo Fisher Scientific) notes that “portable Raman spectrometers” and other handheld devices—though convenient, fast, and inexpensive—can “struggle with detection of fentanyl” and may be prone to “false-positive and false-negative results.”

While it remains ambiguous what exactly last week’s justification was referring to with its mention of “quantum” sensors, there are fentanyl detection methods based in quantum chemistry. The 2024 paper, for instance, explains how “quantum dots” and fluorescent dye can be used to detect fentanyl and 58 of its analogues.

Onnit’s Instant Melatonin Spray Is the Easiest Part of My Nightly Routine

Onnit’s Instant Melatonin Spray Is the Easiest Part of My Nightly Routine


I’ve always approached taking melatonin supplements with skepticism. They seem to help every once in a while, but your brain is already making melatonin. Beyond that, I am not a fan of the sickly-sweet tablets, gummies, and other forms of melatonin I’ve come across. No one wants a bad taste in their mouth when they’re supposed to be drifting off to sleep.

This is where Onnit’s Instant Melatonin Spray comes in. Fellow WIRED reviewer Molly Higgins first gave it a go, and reported back favorably. This spray comes in two flavors, lavender and mint, and is sweetened with stevia. While I wouldn’t consider it a gourmet taste, I appreciate that it leans more into herbal components known for sleep and relaxation.

Instant Melatonin Mist

Keep in mind that melatonin is meant to be a sleep aid, not a cure-all. That being said, one serving of this spray has 3 milligrams of melatonin, which takes about six pumps to dispense. While 3 milligrams may not seem like a lot to really kickstart your circadian rhythm, it’s actually the ideal dosage to get your brain’s wind-down process kicked off. Some people can do more (but don’t go over 10 milligrams!), some less, but based on what experts have relayed to me, this is the preferable amount.

A couple of reminders for any supplement: consult your doctor if and when you want to incorporate anything, melatonin included, into your nighttime regimen. Your healthcare provider can help confirm that you’re not on any medications where adding a sleep aid or supplement wouldn’t feel as effective. Onnit’s Instant Melatonin Spray is International Genetically Modified Organism Evaluation and Notification certified (IGEN) to verify that it uses truly non-GMO ingredients.

Apart from that, there may be some trial and error on the ideal amount for you, and how much time it takes to kick in. Some may feel the melatonin sooner than others. For my colleague Molly, it took about an hour. Melatonin can’t do all the heavy lifting, so make sure you’re ready to go to bed when you take it, and that your sleep space is set up for sleep success, down to your mattress, sheets, and pillows.

I Tested Bosch’s New Vacuum Against Shark and Dyson. It Didn’t Beat Them

I Tested Bosch’s New Vacuum Against Shark and Dyson. It Didn’t Beat Them


There’s a lever on the back for this compression mechanism that you manually press down and a separate button to open the dustbin at the bottom. You can use the compression lever when it’s both closed and open. It did help compress the hair and dust while I was vacuuming, helping me see if I had really filled the bin, though at a certain point it doesn’t compress much more. It was helpful to push debris out if needed too, versus the times I’ve had to stick my hand in both the Dyson and Shark to get the stuck hair and dust out. Dyson has this same feature on the Piston Animal V16, which is due out this year, so I’ll be curious to see which mechanism is better engineered.

Bendable Winner: Shark

If you’re looking for a vacuum that can bend to reach under furniture, I prefer the Shark to the Bosch. Both have a similar mechanism and feel, but the Bosch tended to push debris around when I was using it with an active bend, while the Shark managed to vacuum up debris I couldn’t get with the Bosch without lifting it and placing it on top of that particular debris (in this case, rogue cat kibble).

Accessory Winner: Dyson

Dyson pulls ahead because the Dyson Gen5 Detect comes with three attachments and two heads. You’ll get a Motorbar head, a Fluffy Optic head, a hair tool, a combination tool, and a dusting and crevice tool that’s actually built into the stick tube. I love that it’s built into the vacuum so that it’s one less separate attachment to carry around, and it makes me more likely to use it.

But Bosch does well in this area, too. You’ll get an upholstery nozzle, a furniture brush, and a crevice nozzle. It’s one more attachment than you’ll get with Shark, and Bosch also includes a wall mount that you can wire the charging cord into for storage and charging, and you can mount two attachments on it. But I will say, I like that Shark includes a simple tote bag to store the attachments in. The rest of my attachments are in plastic bags for each vacuum, and keeping track of attachments is the most annoying part of a cordless vacuum.

Build Winner: Tie

All three of these vacuums have a good build quality, but each one feels like it focuses on something different. Bosch feels the lightest of the three and stands up the easiest on its own, but all three do need something to lean against to stay upright. The Dyson is the worst at this; it also needs a ledge or table wedged under the canister, or it’ll roll forward and tip over. The Bosch has a sleek black look and a colorful LED screen that will show you a picture of carpet or hardwood depending on what mode it’s vacuuming in. The vacuum head itself feels like the lightest plastic of the bunch, though.

Right-Wing Gun Enthusiasts and Extremists Are Working Overtime to Justify Alex Pretti’s Killing

Right-Wing Gun Enthusiasts and Extremists Are Working Overtime to Justify Alex Pretti’s Killing


Brandon Herrera, a prominent gun influencer with over 4 million followers on YouTube, said in a video posted this week that while it was unfortunate that Pretti died, ultimately the fault was his own.

“Pretti didn’t deserve to die, but it also wasn’t just a baseless execution,” Herrera said, adding without evidence that Pretti’s purpose was to disrupt ICE operations. “If you’re interfering with arrests and things like that, that’s a crime. If you get in the fucking officer’s way, that will probably be escalated to physical force, whether it’s arresting you or just getting you the fuck out of the way, which then can lead to a tussle, which, if you’re armed, can lead to a fatal shooting.” He described the situation as “lawful but awful.”

Herrera was joined in the video by former police officer and fellow gun influencer Cody Garrett, known online as Donut Operator.

Both men took the opportunity to deride immigrants, with Herrera saying “every news outlet is going to jump onto this because it’s current thing and they’re going to ignore the 12 drunk drivers who killed you know, American citizens yesterday that were all illegals or H-1Bs or whatever.”

Herrera also referenced his “friend” Kyle Rittenhouse, who has become central to much of the debate about the shooting.

On August 25, 2020, Rittenhouse, who was 17 at the time, traveled from his home in Illinois to a protest in Kenosha, Wisconsin, brandishing an AR-15-style rifle, claiming he was there to protect local businesses. He killed two people and shot another in the arm that night.

Critics of ICE’s actions in Minneapolis quickly highlighted what they saw as the hypocrisy of the right’s defense of Rittenhouse and attacks on Pretti.

“Kyle Rittenhouse was a conservative hero for walking into a protest actually brandishing a weapon, but this guy who had a legal permit to carry and already had had his gun removed is to some people an instigator, when he was actually going to help a woman,” Jessica Tarlov, a Democratic strategist, said on Fox News this week.

Rittenhouse also waded into the debate, writing on X: “The correct way to approach law enforcement when armed,” above a picture of himself with his hands up in front of police after he killed two people. He added in another post that “ICE messed up.”

The claim that Pretti was to blame was repeated in private Facebook groups run by armed militias, according to data shared with WIRED by the Tech Transparency Project, as well as on extremist Telegram channels.

“I’m sorry for him and his family,” one member of a Facebook group called American Patriots wrote. “My question though, why did he go to these riots armed with a gun and extra magazines if he wasn’t planning on using them?”

Some extremist groups, such as the far-right Boogaloo movement, have been highly critical of the administration’s comments on being armed at a protest.

“To the ‘dont bring a gun to a protest’ crowd, fuck you,” one member of a private Boogaloo group wrote on Facebook this week. “To the fucking turn coats thinking disarming is the answer and dont think it would happen to you as well, fuck you. To the federal government who I’ve watched murder citizens just for saying no to them, fuck you. Shall not be infringed.”
