Can cells break the laws of thermodynamics?
Our preprint investigates the current scientific controversy. Using our nanosensor, we addressed unexpected artifacts and measured temperature with record accuracy inside cells.

The remarkable work from P. Maurer's lab also independently reports similar artifacts.

www.researchsquare.comInvestigating intracellular heating rates with millikelvin nanothermometryNanothermometry within living cells is an important endeavour in physics,as the mechanisms of heat diffusion in such complex and dynamic environments remain poorly understood. In biology, nanothermometry may offer new insights into cellular biology and open new avenues for drug-discovery. Previou...

I've done some fairly high-level meetings over the last years, but today, I think I can say that they've all been surpassed.
I was invited to a "high-level informal presidential discussion" for the Human Rights Council at the UN to talk about emerging technologies like quantum and AI.

Our definitions of informal are somewhat different, but at least I decided to where shoes.

"Accurate navigation becomes a challenge in real-world scenarios when GPS signals are unavailable," said Sandia scientist Jongmin Lee.

#electronicwarfare units can jam or spoof satellite signals to disrupt troop movements and operations.

"By harnessing the principles of quantum mechanics, these advanced sensors provide unparalleled accuracy in measuring acceleration and angular velocity, enabling precise navigation even in GPS-denied areas."

Masa Galic: specialist in surveillance (lawyer) There's different kinds, not all big brother and panopticon. We have a lot of smart sensors at home. She has a smart camera and baby monitors and smart phones. She thinks we might be less likely to survey individuals than populations. "Digital twin of whole world" “always on data collection”

Ha ha she ends saying it's a good thing that quantum hardly ever actually works.

China might go after the single quantum clock a nation has (Taiwan?) They need some other way to ensure computers don't drift so China can't just knock that out. Then we need also think about signals intelligence. #MASINT will become more important. It will be hard for nations to hide things, especially from space, so won't bother decoding signals. Are there countermeasures to sensing gravity? #privacy #cpdp2024 #quantum #quantumSensing

Hoofnagle wants #privacy people to be thinking about totally new capabilities, like that you can do a lot of quantum sensing from space. You can tell whether a truck has its normal load or maybe a bomb. Quantum radar is stealth sensing -- could maybe detect stealth airplanes, and the quantum array would not be detectable by the advesary. Huge change if no one knows where radar is. Also, cannot be blocked “denied" like GPS is being by Russia right now.

[to be fair, I think he meant the same scale] #privacy #cpdp2024 #quantum #quantumSensing Someone Chris Hoofnagel? wrote a book with the awesome Simpson Garfinkle which is OA on CUP. and aimed at regulators / governance to be clear. Quantum sensing and quantum simulation are both short of quantum computing and will be real sooner. The cryptoanalysis threat is overhyped, and Simpson has ell described how those will actually manifest in Lawfare, but we should focus on sensing…

Some of the problems are that you just can't get this super precise sensitive sensor anywhere near what you actually want to measure.

McKinsey is on this panel & now talking about money. Sizeable investment comparable to #genAI. So VC has confidence. Like blockchain, they are saying "look, you can see it works” trying to dispel doubt, but will it actually be useful? "quantum will have the same impact as genAI” [ha no unless both are 0!]

quantum sensing allows you to measure e.g. weight extremely precise with no calibration just looking at one atom and relying on the physics. So you can weigh a truck, or you can detect magma and predict volcano eruptions, HIGHLY sensitive radio transmissions can be detected, stable in time. Magnetic fields very precise, can see the heart beat. [sounds like the ethics issues will be just like the #neurotech panel] This has all been Philippe Bouyer.

🎉 Exciting News in Quantum Sensing! 🌌

We are thrilled to announce that we've secured a #grant from the Czech Science Foundation (#GAČR) to embark on a groundbreaking #project set to kick off in January 2024! Over the next three years, our team will dive into the fascinating realm of #QuantumSensing with the aim of revolutionizing radio-frequency detection.

Project Overview:
In collaboration with brilliant minds and cutting-edge technology, we will construct a trapping device capable of simultaneous #electron and laser-cooled ion storage. This device is not just a piece of equipment; it's a key to unlocking the potential of the ion-electron #quantum system for detecting #radiofrequency radiation.

Goals and Objectives:
Our journey includes constructing a sensitive ion vibration detection system, predicting coupling strength, exploring temperature dependence, and observing the dynamic behaviour of the quantum system. We're not stopping there—our team will also test the system's reaction to artificial radio-frequency signals and dive into theoretical investigations on detecting signal phase and direction.

#Potential #Impact:
Imagine a miniature planar trap equipped with our radio-frequency detection scheme, designed using cutting-edge #microwave #circuit materials developed in tandem with this project. The implications are vast, from enhanced #communication systems to novel sensing applications.

#Patent-worthy #Innovation:
As the project unfolds, we'll be patenting the design of the planar #trap and related circuitry, ensuring that our pioneering work receives the recognition and protection it deserves.

Stay tuned for updates as we dive deep into the mysteries of the ion-electron quantum system! 🚀

The idea of trapping electrons and laser-cooled ions in a microwave ion trap and using it to detect incoming radio-frequency wave to detect enemy aircrafts. The oscillation of electrons induced by the incoming waves will be read out through laser-cooled ions. Electrons are cooled by laser-cooled ions because they are bound together by invisible springs of Coulomb interactions. By LimeWire
