Speaker: Marco Lanzagorta, Naval Research Laboratory
The National Academies of Sciences, Engineering, and Medicine organized a half-day colloquium and webcast sponsored by the Office of the Director of National Intelligence to explore some of the latest developments in quantum sensing and quantum communications. This unclassified event featured individual presentations and a panel discussion on quantum concepts and technologies as they relate to the state of the art. - Наука та технологія

Besides the military application, since a lot of research funding been redirected this way these days, I can see some interesting civil applications of this. Better light detecting devices with higher noise reduction opens up for hugely improved camera, and possible telescope, technology. But I guess it will take some time to minimize the quantum state generators suitable for the consumer market.
Exceptionally interesting
How do you throw a photon like a curveball and then measure it?
May I get the reference study material about the topic
Thanks sir
Excellence discussion.
Outstanding!! Now if someone could just apply detecting targets at zero decibels to detecting catastrophic sized asteroids, Humanity may actually have a small chance of survival.

@@marco-yq4xg notice how interferometric advancements weren't talked about in the paired photon comparison radar system! but at least synthetic apertures were mentioned with a system that will be earth bound for a while! (unless they got some solid state entangling laser element array thing going on)
Depths of richly robust intelligence
the gravimetric detector has such obvious utility for theoretical physics, I couldn't believe he billed it as a submarine tracker. the quantum gravimeter is literally a tool for understanding quantum gravity. at that sensitivity you could see the cosmic gravitational wave background, much less perform endless experiments on entanglement under gravity.
That's not completely correct as what you said is more incorrect than it is factually correct.... so yes it is well understood in the physics community that this type of interferometer would be a useful tool for taking measurements of gravity at the atomic scale though we already understand how gravity works at that length scale (all current models predict how gravity operates at that length scale) and all current experiments support these models so nothing new would be learned by having a gravitational sensor only that sensitive in respects to gravity in if itself, hence why all of the other uses for a Wigner interferometer and why it is truly an important piece of technology i.e. Quantum computing, quantum radar, quantum communication, etc all being extremely important i.e. Much more important than something we already understand and know, also what you are incorrect about is the sensor being sensitive for the microwave background when this type of sensor has nothing to do with looking at that specific bandwidth of spectrum.... this detector would not be able to euclidate quantum gravity like you seem to suspect, much more is required to give an account of quantum gravity and a comprehensive quantum theory of gravity....
@@metatron5199 sorry, I think my wording was unclear. while this sensor doesn't have the resolution to detect gravitational changes below the atomic level, it would still be extremely useful to have a bench-top detector for exploring whether the uncertainty principle applies to gravitational waves caused by large molecules, since this is still an unresolved question, and Freeman Dyson conjectured that gravity might not be uncertain (unlike the other forces.) performing this experiment would be quite useful for seeing whether the regime of quantum gravity is on the right track, even if it reveals no other details about its mechanistic underpinnings.
the second application would be to measure the cosmic *gravity* background (*not* the CMB or CvB) - by which I mean the ripples in spacetime left over from the first second of the big bang, which have been traveling since inflation. indeed, checking Wikipedia, there are already other proposals using other instruments to detect this signal, though something like a quantum gravity detector would be a much more ideal device.
hopefully that makes sense.
If they are entangled you should be able to se a change on the one the the one of the pair you have at home.
But really what are the realistic range of a quantum radar, seems it need unimaginably power to make the range better then the distance a powerful normal radar can detect a stealth plane.
Anyway for a really long time, if it were possible to make one what would the price and size be?
To use entangled particles for communication seems more probable, in our life time and to a price and size that would make it worth using. For space probes, subs and classified information.
But use it like he describes for communication seems like a big waist. You just need one or two entangled particles in each end and the ability to measure and influence them.
Well you just send one stream of photons to a target like in normal radar,but unlike in it you just observe the changes on the other stream of photons of opposite spin (for example) at "home"instead of waithing for echo of the "same" ones,so they actualy take 1/2 of path which under the inverse square law actually takes way less power,is way more accurate since it takes effectively zero time to react and you can't hide from it with any method that weakens the return signal since they don't rely on it and all it takes is any change on those photons for which you just have to be physically there for detection.sry for bad eng
its about making things
invisible ....
hahaahah the cats at the end!
I was just listening to an extremely intelligent man. Then I ended up in the comment section.
Future technologies.

BUT WHY OH WHY
like in the past, those breaktrough always first o to be applied in warfare !!!?????????????? :-(
We didn't learn anything from the past !
How can we work on Peace when we always think and give more power, energy and money to War.
If history repeats it's self history had a drug problem!
better radar is easier to use defensively, harder to use offensively.

GOOD SPEAKER! GOOD SALESMAN (CHINESE ARGUMENT)
turn YOUR camera off, ... can YOU see me, ...did you KNOW i was going to ask you that,... did you ask me that already,....
what?
There opening Pandora's box using technology given by the fallen angels.
Since we are talking about (discovering) knowledge, who, or what, do you identify as the "fallen angels"? Would you call it "revelations" or "submission" or do you believe researcher are handed knowledge, and/or items, in first person by these beings?
@@jomen112 he might be one of those weird alien believers. it was a great psyops campaign after all, stretching to this day. always changing information. other countries give it to us more or less on the straight and narrow. nope, not ours (assuming you're team USA).
"the usa is so far behind in the Q race, we'll just show you by how far China is winning"
One might take Russian statements, regarding stealth detection, such as "you will be surprised with what we can detect" as a hint that they already have operational quantum-radars, or they simply know how to distinguish a bird flying at Mach 1 from a man made object.

Right. The Russians are so advanced, they failed repeatedly to stop US and Israeli attacks on their Syrian ally. They can't even shoot down slow flying non stealthy cruise missiles and unstealthy Gen 4 aircraft designed in the 70's. The Israelis have been using US aircraft, including the F-35 to pick off Russian-Syrian anti-aircraft missile batteries.
Back in October of 2016, just before Trump was elected president, the Russians warned the US and our allies not to attack Assad's forces in Syria. They said they had their missiles ready and in place to shoot down any missiles or aircraft attacking their ally.
