"Researchers from Princeton and MIT have developed a method to intercept underwater communications from the air, challenging long-standing beliefs about the security of underwater transmissions." (ScitechDaily, Not So Secure: Drones Can Now Listen to Underwater Messages)

"The team created a device that uses radar to eavesdrop on underwater acoustic signals, or sonar, by decoding the tiny vibrations those signals produce on the water’s surface. In principle, the technique could also roughly identify the location of an underwater transmitter, the researchers said." (ScitechDaily, Not So Secure: Drones Can Now Listen to Underwater Messages)

New MIT drones can use radars to see submarines. They can hear the underwater messages. Submarines are used to communicate with each other. Drones can also connect themselves to the submarine's hull. They can slip into the harbor and then connect themselves to submarines. 

Those drones can hear everything inside the submarine. This is why submarines should have a vacuum layer between the inner and outer hulls. That vacuum layer makes it harder to hear things. That the crew says in the submarine. That vacuum can also decrease the noise from its engines. 

Drones can endanger privacy in many ways. They can take images of buildings. They can hear what people say in their rooms. They can carry normal and laser microphones in the houses. They can see through clothes using IR cameras. Drones can also put sensors on the data cables they can take images on screens. Drones can carry plasma- and spectroscopic sensors that allow them to see things like chemical compounds of the fuel, by analyzing exhaust gas.

By shooting targets using low-power laser systems, the plasma sensor sees the chemical compounds of the materials. So those drones can see many things. That humans cannot see.

But drones can also hear underwater communication. They can use acoustic microphones (hydrophones) to hear things. Like acoustic messages from submarines. Those systems can also hear sounds from the submarine engines and propellers. There is a possibility that the underwater drone travels near the submarine and connects itself to the submarine's hull. That allows those drones to hear everything that people say in the submarine. New drones can operate airborne and underwater. And they can operate in many ways against the enemy. 

Advanced acoustic detectors can also use laser beams and radar systems to see how water molecules move. Those miniaturized systems can perform almost the same missions as manned helicopters. 

The underwater drone can also use things like hollow warhead detonators to damage the submarine's outer shell. Those small drones can make holes in the hull like torpedo tube hatches. And they can damage submarine communication masts. Drones can also have acoustic transmitters that uncover the submarine's positions.

Quantum computers can make fully automated systems more efficient than ever.

"Quantum information could enhance coordination between autonomous devices, improving efficiency and bandwidth use. Experiments show shared quantum qubits enable influence without direct communication." (ScitechDaily, Quantum Computing Could Make Self-Driving Cars More Efficient Than Ever)

That is not a very big surprise. Quantum computers can solve mathematical problems and handle linear data faster than binary computers. The quantum computer solves a mission. That takes even thousands of years if operators use binary computers. Quantum computers can handle data flow and control sensor and system fusion faster than any binary computer. 

That's why quantum computing can make self-driving cars more effective than ever. In future visions, self-driving cars communicate with traffic control cameras and other systems like GPS. 

Starlink and other satellite-based solutions offer the possibility that self-driving vehicles can communicate with each other and the computer centers. The self-driving cars can create morphing neural networks with other systems and devices. That allows them to operate safely. The thing that makes self-driving cars interesting in the city areas is this. The car can leave the owner at the office's door, and then drive back home. The electric vehicle doesn't need fuel. 

And at home the car can have a manipulator's arm, that it puts into its loading point. The self-driving cars can cooperate with things like drones. Which can offer the possibility to check things. Like rush hours. The same technology allows to make aircraft swarms or land vehicles like tanks that can communicate with each other, long-range drones, and other types of devices and vehicles. 

A Large language model, LLM needs very high-power calculation capacity. The quantum computers can solve that problem. The AI-based operating systems can connect morphing neural networks with quantum computers. The idea in those hybrid systems is when a morphing neural network requires the quantum computer's assistance it calls quantum computers to share their calculation capacity. The morphing neural network can connect robots into one entirety. And it can emulate quantum computers. The morphing neural networks allow to reprogram cars in seconds. 

That means the car can call other robots to assist it. While a person works the morphing multipurpose robot system can call to the local market and then the robot can collect things into shopping bags and then load them into the car that drives those things to home. The AI-controlled drone can fly those things to the balcony. The morphing neural network allows the system. With limited calculation capacity can call other system's assistance. That makes also limited systems more effective. 

Light tornadoes. Along with high-speed, high-power radio waves can increase network power.

"By employing quasicrystals, researchers at Aalto University have found a new way to enhance data transmission using light vortices, potentially multiplying the current capacity of optic fibers by 8 to 16 times. Credit: SciTechDaily.com" (ScitechDaily, Laser Storms: Physicists Create “Light Hurricanes” for 16x Faster Data Transmission)

The light tornadoes can increase the speed of the network by 16X. From its present speed. The light tornado is one of the ways how to make faster and probably safer networks. The light-based network would be the tool of the future. The laser-based networks are easier to protect. And they can support things like quantum computers better than modern electric-based networks.

When a light tornado travels inside another laser ray, that prevents the attackers from seeing the message. That is an idea of the quantum network. In quantum networks, the attacker cannot reach information without disturbing the network. If somebody puts a sensor through the laser ray. That thing means that there is a cut in the protecting laser ray. The optical networks are harder to jam than electric or radio wave-based systems. The problem is that the laser ray cannot travel through barriers like walls. 

It's possible. The system shoots laser rays to the sensor, which resends them through the wall using an optical data cable. Inside the house, the system can use radio waves. If the house is at the same time as the Faraday cage that radio impulse cannot travel out from it. The Faraday cage denies the inside radio waves travel out from the house. The radio wave-based relay station can send data because people who are outside the Faraday cage cannot hear the signal.

Magnetar is a neutron star with an extremely powerful magnetic field. The magnetic field stresses the plasma ring around the magnetar. When the energy level in plasma is high enough, that plasma sends radio waves in both directions. About half of that energy goes to space. But half of it travels into the plasma ring. That radio wave impacts a very strong magnetic field. 

That increases its power. The thing is that the energy level in the plasma ring must be higher than in the magnetar so that the radio wave can travel inside it. The impacting radio waves form the standing wave. And then sooner or later. The energy that comes or reflects from the plasma presses the standing wave against the magnetar's spin axle. And it's possible that researchers can copy those conditions to communication systems. 

One way to make the network secure is to use coherent radio waves, or radio masers to communicate. 

The knowledge of the fast radio burst, FRB can make it possible to create extremely accurate high-power radio bursts. The idea is that the system can make the plasma ring around the magnets. Then the system shoots high-energy impulses to those plasma rings. The plasma ring sends the extra energy into the middle of the plasma ring. If that kind of reaction happens near neutron stars the plasma ring sends the radio burst straight to the spin axle of the neutron star. 

That thing makes it possible that the plasma and electromagnetic fields will increase the power of the radio bursts. The idea is that there is an energy stick in the middle of the neutron star. When the plasma ring that orbits the neutron star at its equator sends energy impulses, that energy stick between neutron star poles sends the energy impulses to the neutron star's poles. 

But the knowledge of things like fast radio bursts can make it possible to create a network that is hard for jammers. The extremely powerful radio maser can be the plasma rings around the antenna. Then that plasma sends radio impulses to the antenna. And that thing can send high-energy radio waves that can be used as a communication tool. But those radio waves can destroy drones or computers. The crossing of radio waves can also create electric arcs.
