Graph representations can solve complex problems in natural science, as patterns of connectivity can give rise to a magnitude of emergent phenomena. Graph-based approaches are specifically important during quantum communication, alongside quantum search algorithms in highly branched quantum networks. In a new report now published on Science Advances, Max Ehrhardt and a team of scientists in physics, experimental physics and quantum science in Germany introduced a hitherto unidentified paradigm to directly realize excitation dynamics associated with three-dimensional networks. To accomplish this, they explored the hybrid action of space and polarization degrees of freedom of photon pairs inside complex waveguide circuits. The team experimentally explored multiparticle quantum walks on complex and highly connected graphs as testbeds to pave the way to explore the potential applications of fermionic dynamics in integrated photonics.

Complex networks

Complex networks can occur across diverse fields of science, ranging from biological signaling pathways and biochemical molecules to exhibit efficient energy transport to neuromorphic circuits across to social interactions across the internet. Such structures are typically modeled using graphs whose complexity relies on the number of nodes and linkage patterns between them. The physical representation of a graph is limited by their requirement for arrangement in three-dimensional (3D) space. The human brain is a marked example of scaling behavior that is unfavorable for physical simulation due to its staggering number of 80 billion neurons, dwarfed by 100 trillion synapses that allow the flow of signals between them. Despite the number of comparably miniscule volume of nodes, discrete quantum systems faced a number of challenges owing to complex network topologies, efficient multipartite quantum communications and search algorithms.

In a world-first, a tattoo artist remotely needled a tattoo into a person in real-time using a 5G-powered robotic arm. Read it here.

The world’s first remote tattoo was completed by a 5G-powered robotic arm fitted with a tiny needle.

Tattoo artist Wes Thomas drew the design on a mannequin arm while a robot in another location copied his motions on Dutch actress Stijn Fransen’s wrist.

WASHINGTON — A Falcon 9 launched another set of Starlink satellites March 14, with the rocket’s first stage setting a record with its ninth launch and landing.

The Falcon 9 lifted off from Launch Complex 39A at the Kennedy Space Center at 6:01 a.m. Eastern. The upper stage deployed its payload of 60 Starlink satellites into orbit 65 minutes later, bringing the size of the broadband internet constellation to 1260 satellites.

The launch was the eighth for the Falcon 9 this year, and took place a little more than 72 hours after another Falcon 9 launch of Starlink satellites. Six of the eight Falcon 9 launches this year have been dedicated to Starlink, and one of the other two, the Transporter-1 dedicated rideshare flight, also carried 10 Starlink satellites.

CAMBRIDGE, Mass.—(BUSINESS WIRE)—Engineers from HyperLight, a leader in the commercialization of thin-film lithium niobate (LN) photonic integrated circuits (PICs), have achieved breakthrough voltage-bandwidth performances in integrated electro-optic modulators. The broadband electro-optic PIC could lead to orders of magnitude energy consumption reduction for next generation optical networking.

“We believe the significantly improved electro-optic modulation performance in our integrated LN platform will lead to a paradigm shift for both analog and digital ultra-high speed RF links” Tweet this

Energy consumption in optical networking for ethernet, data centers and 5G is soaring as a result of the rapidly growing data traffic. This is because of the limited performance of existing electro-optic modulators, the key element in converting data from the electrical to optical domain at high speed for optical networks. Current electro-optic modulators require extremely high radio-frequency (RF) driving voltages (5 V) as the analog bandwidth in ethernet ports approaches 100 GHz for future terabits per sec capacity transceivers. In comparison, a typical CMOS RF modulator driver delivers less than 0.5 V at such frequencies. Compound semiconductor modulator drivers can deliver voltage 1 V at significantly increased cost and energy consumption but still fall short to meet the optimum driving voltage. The limited voltage-bandwidth performance in electro-optic modulators poses a serious challenge for meeting tight power consumption requirements from network builders.

Elon Musk’s SpaceX is preparing to further expand testing of its Starlink satellite internet in a test for the U.S. Air Force, an FCC request revealed.

Elon Musk’s SpaceX is preparing to further test its Starlink satellite internet in a demonstration for the U.S. Air Force, the company revealed in a recent request to the Federal Communications Commission.

“SpaceX seeks to make minor modifications to its experimental authorization for additional test activities undertaken with the federal government,” the company wrote to the FCC in a filing on Thursday.

These shifting dynamics in India’s digital marketplace are yet another warning sign of what’s been dubbed the splinternet, foreshadowing a possible world where each country sticks to its own apps and abandons the open and global nature of the internet. For now, however, these homegrown apps may find it difficult to compete at the same level unless the government decides to ban Facebook and Twitter, too.

While Twitter finds itself in a prolonged standoff with the Indian government over the company’s refusal to take down certain accounts, a senior executive of a very similar Indian social network says the sudden attention on his app has been “overwhelming.”

“It feels like … you’ve just been put in the finals of the World Cup suddenly and everyone’s watching you and the team,” Mayank Bidawatka, co-founder of Koo, told CNN Business.
