Quantum Signals Just Reversed Direction 🚀🔗 For years, scientists believed quantum signals could only travel downward — from satellites in space to receivers on Earth. Now, researchers from UTS Sydney have flipped that idea. They’ve shown it’s possible to send quantum-entangled photons upward, from Earth to a satellite — a feat once thought impossible. This breakthrough means future quantum networks could use ground-based transmitters (cheaper, more powerful, easier to maintain) to connect quantum computers globally via low-orbit satellites. It’s a major step toward building the Quantum Internet — where entanglement becomes as common as electricity, powering communication systems that are unhackable by design. #QuantumComputing #QuantumInternet #SpaceTech #DeepTech #raktimthoughts

Earth-to-Orbit Quantum Beams: The Next Leap Toward a Global Quantum Internet Breaking the Downlink Barrier For the first time, scientists have demonstrated that quantum light beams can be transmitted from Earth to orbit, overturning long-standing assumptions in quantum communications. Conducted by researchers at the University of Technology Sydney (UTS), the breakthrough confirms that “uplink” communication—once thought unworkable due to atmospheric interference and signal loss—is now feasible. Until now, all quantum networks relied solely on downlink transmissions from satellites to Earth. From Downlink to Uplink: Reversing the Quantum Flow Past Milestones: 2016 – Micius Satellite (China): First major quantum satellite enabling space-based quantum encryption. 2025 – Jinan-1 Microsatellite: Established a 12,900-km quantum link between China and South Africa, setting a new record. The Uplink Breakthrough: Led by Professors Alexander Solntsev and Simon Devitt, the UTS team proposed firing two single photons from separate ground stations to a satellite orbiting 500 km above Earth at 20,000 km/h. These photons are synchronized to meet perfectly in space and undergo quantum interference, proving an uplink connection is achievable. Real-world effects—such as background light, atmospheric distortion, and optical misalignment—were factored into their model, confirming operational feasibility. Why It Matters: Enabling the Quantum Internet Bandwidth Expansion: Uplink systems can transmit more photons, providing the bandwidth needed for linking quantum computers rather than just encrypting messages. Lightweight Infrastructure: Satellites would only require small optical receivers instead of heavy photon-generation units, reducing cost and complexity. Scalable Global Networks: Multiple low-orbit satellites could create continuous quantum coverage, laying the groundwork for a global quantum internet. The Road Ahead This discovery redefines the architecture of future quantum communication. By proving that signals can travel both ways, UTS researchers have opened the door to bi-directional quantum networks—a critical step toward secure, high-bandwidth connectivity across continents and space. Within decades, quantum entanglement may become as ubiquitous and invisible as electricity, powering a new class of interconnected devices and nations.

Feasible Quantum Uplink: Scientists Prove Quantum Signals Can Be Sent from Earth to Orbiting Satellites Turning the Quantum Network Upside Down In a groundbreaking advance for quantum communications, researchers at the University of Technology Sydney (UTS) have demonstrated that it is feasible to transmit quantum signals upward—from Earth to a satellite—a concept once dismissed as impractical. The finding, published in Physical Review Research, could revolutionize how future quantum internet and secure global networks are built. Breaking a Long-Standing Barrier Until now, quantum satellites like China’s Micius and Jinan-1 operated on a “downlink” model, where entangled photons were generated in orbit and beamed down to ground stations for ultra-secure data transfer. The new UTS study, led by Professors Simon Devitt and Alexander Solntsev, flips this paradigm—showing that “uplink” entanglement, where photons are generated on Earth and transmitted skyward to meet in orbit, is theoretically viable even under real-world atmospheric and optical conditions. Their modeling accounted for challenges such as atmospheric turbulence, background light, and satellite motion—and still confirmed that quantum interference between two single photons, fired simultaneously from separate ground stations to a fast-moving satellite, can occur. This overturns the long-held belief that scattering and loss would make uplink transmission impossible. Why It Matters Uplink systems could transform quantum communication by shifting complexity to the ground. Ground-based transmitters can draw more power, are easier to maintain, and can generate stronger photon sources—reducing the need for costly, high-energy payloads in orbit. This enables compact, low-cost satellites equipped only with lightweight optical units, paving the way for high-bandwidth quantum connections between continents. “The uplink method could provide the bandwidth quantum computers need to talk across the globe,” said Professor Devitt. “Instead of bulky quantum hardware in space, satellites could act as simple relays, keeping cost and size down while enabling scalable global networks.” Toward the Quantum Internet The team envisions future tests using drones and balloon-mounted receivers before expanding to low-Earth orbit satellites. Long-term, this could enable a quantum internet, where entanglement becomes as commonplace and invisible as electricity—an unseen infrastructure powering secure communication and quantum computing worldwide. As Devitt summarized, “In the future, quantum entanglement will be a utility—generated, distributed, and consumed seamlessly across the planet.” I share daily insights with 32,000+ followers and 11,000+ professional contacts across defense, tech, and science.
