I'd press it twice, but I would much more like an 'undo' button for the last decade until we've figured out how we are going to deal with mass unemployment and mental issues as a result of people no longer seeing (1) a future and (2) their sense of self worth as related to having a career erased, and finally how to ensure that the least scrupulous actors are not going to be the ones that hold the keys to these very powerful devices.

That page uses the older versions of "SWaP-C2 Optimized[1]" meme, I would guess it might have not been updated in 3-5 years.
1: Stands for "Size, Weight, and Power [and] Cost [and] Cooling Optimized", defense industry equivalent of self awarded gold medal stickers on product packaging, apparently
That looks like it is definitely real but also extremely fragile and there is no mention of any performance specs. But that's 3 years old now and no product(s) available yet.
Oh, that's very neat, I can imagine that some future front-end to a SDR will have no antenna at all, just a bunch of solid state.
The abstract of the paper:
"""Coupling a Rydberg vapour medium to both microwave and optical fields enables the benefits of all-optical detection, such as minimal disturbance of the measured field and resilience to very strong signals, since no conventional antenna is required. However, peak sensitivity typically relies on adding a microwave local oscillator, which compromises the all-optical nature of the measurement. Here we introduce an alternative, optical-bias detection, that maintains fully optical operation while achieving high sensitivity. To address laser phase noise, which is critical in this approach, we perform a simultaneous measurement of the noise using a nonlinear process and correct it in real time via data processing. This yields a 35 dB improvement in signal-to-noise ratio compared with the basic method. We demonstrate a sensitivity of 176 nV / cm / sqrt(f Hz) , reliable operation up to 3.5 mV/cm at 13.9 GHz, and quadrature-amplitude modulated data transmission, underlining the ability to detect microwave field quadratures while preserving the unique advantages of all-optical detection."""
Emph. mine, at about -36 dBm that's not super sensitive yet though, but that formula suggests that at lower frequencies it should be a lot more sensitive.
The abstract is not very clearly written. The 3.5 mV/cm is the maximum detectable field strength before the system starts to saturate. I would be interested how the sensitivity compares to conventional (cryogenic) semiconductor detectors.
Because all of the signals are superimposed. So if your receiver isn't selective it will show all of them at once and if you then demodulate selective parts of the spectrum by filtering you can isolate the signals individually.
Think of any antenna: it is just a rod or a coil, it may have a specific frequency that it particularly likes because that is a nice fraction of its wavelength or close to its own resonance frequency, but that doesn't mean it isn't going to receive all the other signals to greater or lesser extent as well. The ratio between that one that it likes and the rest is called selectivity. The lower the selectivity the more evenly you will receive all signals at the same time.
Usually receivers have a tuned front-end to get as much of the signal you want and to repress the rest as much as possible but that is optional, you can have a wideband front end just the same.
Also Panama's population and land area are an order of magnitude smaller than these Middle East states, and they were already an American client state in the past.
I think you are speaking about the last Shah's first son: Reza Pahlavi. You can read about his planned policy for Iran here: https://rezapahlavi.org/en
To quote:
> For the transition from the Islamic Republic to a national, secular, and democratic government
One idea is to transition to a secular democracy with a figurehead Shah like a northern European (or Japanese) monarchy. Also, my personal opinion: I think it is fine if they want to incorporate aspects of Islamic religious culture into their government. After all, it is their country. Example: The national parliament and political parties might be required to secular (at least in name), but they may wish to continue to support religious institutions using tax payer money, including masjids (places of prayer) and Islamic monasteries.
An interesting point of comparison: (1) Malaysia isn't really secular (but they may claim it); (2) Singapore is fully secular; (3) Indonesia is secular (or "pan-religious"), but is still largely guided by Islamic relgious culture in their democractic systems.
What he says he's planning and what he will do are not necessarily the same thing. The former Shah's regime was really bad and paved the way for everything that happened afterwards. Between the SAVAK (which tortured and executed quite a few of those in opposition to the Shah regime) and excesses like Persepolis (https://en.wikipedia.org/wiki/2,500-year_celebration_of_the_... ) there was created an atmosphere in which the mullahs seemed like a viable alternative.
To return to a scion of the man who put that all in place would - in my opinion, of course - be a massive mistake.
Keep in mind that the Shah was a client of the United States and the United Kingdom and that his son isn't doing this out of the goodness of his heart but because he wants what he thinks is his birthright back (he's been pretty vocal about that since his late teens), and that he has been living off wealth stolen from the Iranian people and squirreled out of the country by his father.
Of course he would present this as a transition but just wait until his ass hits that pluche and see if it isn't going to take another revolution to dislodge him.
