Quantum Radar

Quantum Computing is about to upend our Digital Privacy, but I only just learned Quantum Algorithms will do the same for Military Stealth too…

Currently, stealth works in a couple of basic ways:

  1. Minimising the reflected radar signal.
  2. Sending back a fake signal.
  3. Messing with the electronic brain of the radar system (but this is more electronic warfare than stealth).

For a radar system, both 1 and 2 can be circumvented if there is someway for it to focus exclusively on the echoes from its own beam by filtering all the other photons. In this way, it can concentrate on the real target and ignore innocent but confusing background noise, and deliberate spoofing with fake signals.

Radars today try to filter out these false signals by focusing on specific frequency ranges and very precise timings, but clever EM warfare packages are able to spoof these techniques.

What the radar needs is a way to securely ‘tag’ its own photons, so that it can filter and ignore anything else…

Enter the Quantum Radar…

“Only a few of the photons sent out will be reflected back if they hit a stealth aircraft. A conventional radar wouldn’t be able to distinguish these returning photons from the mass of incoming signals created by natural phenomena—or by radar-jamming devices. But a quantum radar can check for evidence that incoming photons are entangled with the ones held back. Any that are must have originated at the radar station. This enables it to detect even the faintest of return signals in a mass of background noise.

Confused signals from target, environment and spoofing.

Background noise is filtered by quantum algorithms which only allow photons through if they are entangled with clones of the transmitted photons held in the radar’s ‘quantum memory’ .

The target is revealed.
However faint the real signal, it can never be swamped because only reflections from the radar station are considered.



Tech from Singularity’s Children: 3D Printing Organs in Space

3D Tissue Printing in Space is another technology I play with in my Singularity’s Children books.

The ultra-rich have found a new way to stave of a visitation from the grim-reaper by packing themselves in gelly and shooting themselves into orbit. There, cloning, cybernetics, and 3D tissue printing can fashion them new bodies.

FT – Small ‘organoids’ grown in the lab could be used to treat chronic conditions

In Space, the printer can place cells anywhere without worrying about gravity deforming the growing wet blob. Nutrients can be misted across the pulsing membranes as a new vessel for an oligarchs consciousness takes shape…

Once the body is done and ready for a freshly scooped out brain, all the fiddly neural wiring can be handled by software. Bulk connections are made in the brain-stem and dynamically mapped to sensations or actions in the synthetic body.

That’s the SciFi, this is the fact:

“In the microgravity environment, cells exhibit spatially unrestricted growth and assemble into complex 3D aggregates, in contrast to typical growth in monolayer (2D) cultures as occurs on Earth. For over two decades, investigations conducted in space and on Earth have shown that 3D culture supports the generation of tissue-like characteristics in vitro that are more biologically representative of native in vivo-like cell growth and function.” 3dprint.com

Science from Singularity’s Children: Smart Cetaceans

In my Singularity’s Children series, animals are smart, but get a raw deal because they are hampered by a lack of hands and tongues, a deficiency overcome by the BugNet, AKA: IOA, The Internet of Animals.

The more science tells us about how smart —and devious— animals really are, the more convinced I become that we have already discovered “Alien Intelligence”.

Humpback Whale Communication and the Search for Alien Intelligence, watch the video here:

“The study of animal communication challenges our ideas of intelligence and informs our search for life in the universe. Among the most fascinating of vocalizations are the songs and sounds of humpback whales.”
