This 16g open-source autopilot can make drones smarter, safer
Posted by Shubham Ghosh Roy in categories: drones, internet, robotics/AI
ModalAI, a Blue UAS framework manufacturer of autonomous drone technology, says it has developed the world’s smallest and most advanced autopilot built in the USA. Weighing only 16 grams, ModalAI’s VOXL 2 is designed specifically for GPS-denied, autonomous drones with obstacle avoidance.
It is powered by the Qualcomm Flight RB5 5G platform and integrates a PX4 real-time flight controller with an 8-core CPU, a GPU and NPU that provide a combined 15 Tera Operations Per Second (TOPs), seven image sensors, and TDK IMUs, and barometer.

Robot Highlight—Mini Cheetah Hits New Speeds
Posted by Shubham Ghosh Roy in categories: internet, robotics/AI
Highlighting recent robotics research, MIT’s robot “mini cheetah” combines the best of electronics and machine learning to zoom towards the future.
Four-legged animals have long been a popular platform for basing walking robots on. Some of the most widely internet-famous robots are the quadrupeds that have come out of the Massachusetts Institute of Technology (MIT), such as Boston Dynamics’ Spot (a spin-off of MIT bought by Hyundai) and the MIT Mini Cheetah.

Elon Musk’s SpaceX Signs First Deal With Major U.S. Airline To Provide Free Wi-Fi For Passengers
Posted by Kelvin Dafiaghor in categories: Elon Musk, habitats, internet, satellites
Elon Musk’s SpaceX has signed its first ever deal with a major U.S. airline to provide wireless internet to passengers for free using the Starlink satellite network.
The deal with Hawaiian Airlines, which could be implemented as soon as next year, is expected to increase pressure on rival airlines to provide free Wi-Fi for passengers.
“Hawaiian doesn’t currently offer inflight Wi-Fi and has an extensive network of flights over the Pacific Ocean, serving the mainland U.S., Japan, Australia and New Zealand, among other destinations, from Hawaii,” CNBC reported. “It plans to offer Starlink connectivity on its flights out of its home state to cities throughout the mainland U.S. and to its international destinations.”

Parallel quantum simulation of large systems on small NISQ computers
Posted by Quinn Sena in categories: computing, internet, quantum physics
Basically all this says is that a basic quantum computer made of a simulation of an infinite quantum computer. So essentially infinite quantum computers could make the internet much more instant.
To parallelise our simulation on a small NISQ machine, we first identify partitions of the system where the effect of one partition upon the other can be summarised by a small amount of information. This is achieved by making Schmidt decompositions across the cut: \(\left|\psi \right\rangle =\mathopsum
olimits_alpha = 1Dlambda ^alpha \left|phi _L^alpha \right\rangle \left|phi _R^alpha \right\rangle,\) where \(\left|phi _L^alpha \right\rangle\) are an orthonormal set of states to the left of the cut and \(\left|phi _R^alpha \right\rangle\) the same on the right. The λα are known as the Schmidt coefficients and D the Schmidt rank or bond order. Retaining λα only above some threshold value provides a way to compress representations of a quantum state; the MPS construction can be obtained by applying this procedure sequentially along a spin chain4.
If an observation is made on the right-hand-side of such a cut, the effect of the quantum state on the left upon the observation can be summarised by just D variables corresponding to the Schmidt coefficients. This same effect can be achieved by an effective state on a spin chain of length \(log\,_2D\) —see Fig. 1 —which can be parametrised on the quantum circuit by an SU (D2) unitary VL. This encodes both the Schmidt coefficients λα and the orthonormal states \(\left|phi _L^alpha \right\rangle\). The latter does not contribute to observables on the right and so in principle, VL can be parametrised by just D variational parameters. The precise numerical values must be determined by solving a quantum mechanical problem on the left of the system. Similarly, for observations made to the left of the cut, the effect of the right-hand side can be summarised by a unitary VR.

Bart Blommaertsif it helps. But don’t cut internet cables with that thing!!
Andreas StürmerFinally. Is it going to be a rail or car tunnel?

Researchers break world record for quantum-encrypted communications
Posted by Genevieve Klien in categories: cybercrime/malcode, encryption, internet, quantum physics
Researchers in Beijing have set a new quantum secure direct communication (QSDC) world record of 102.2 km (64 miles), smashing the previous mark of 18 km (11 miles), The Eurasian Times reported. Transmission speeds were extremely slow at 0.54 bits per second, but still good enough for text message and phone call encryption over a distance of 30 km (19 miles), wrote research lead Long Guilu in Nature. The work could eventually lead to hack-proof communication, as any eavesdropping attempt on a quantum line can be instantly detected.
QSDC uses the principal of entanglement to secure networks. Quantum physics dictates that entangled particles are linked, so that if you change the property of one by measuring it, the other will instantly change, too — effectively making hacking impossible. In theory, the particles stay linked even if they’re light-years apart, so such systems should work over great distances.
The same research team set the previous fiber record, and devised a “novel design of physical system with a new protocol” to achieve the longer distance. They simplified it by eliminating the “complicated active compensation subsystem” used in the previous model. “This enables an ultra-low quantum bit error rate (QBER) and the long-term stability against environmental noises.”
