Quantum ‘compass’ technology aids in navigation without use of GPS satellites
Scientists from Imperial College London and M Squared, a photonics and quantum technology company, have created a portable quantum accelerometer which enables location tracking without the aid of GPS satellites. As demonstrated at the National Quantum Technologies Showcase 2018 in London, the device utilizes ultra-cooled atoms and lasers to measure position with precision made possible by quantum mechanics. The system is currently designed to be used for navigating large vehicles such as ships and trains, but smaller-scale devices will be available as the technology develops.

The reliance on global navigation satellite systems such as GPS has a few significant shortcomings that the quantum accelerometer would overcome. Satellite signals can be blocked or jammed, interfering with the systems that rely on the data being provided. Threats such as electromagnetic pulse (EMP) attacks on a massive scale, now closer to reality with nuclear capability developments around the world, would cripple any technology relying on satellite systems.
The financial burden of GPS failure is also a serious consideration driving the innovation behind this device. In M Squared’s press release announcement, it was estimated that each day without GPS services in the United Kingdom would cost the country 1 billion pounds. Since it’s a self-contained system not reliant on external signals, a quantum accelerometer would not be at risk for these types of security or financial fallouts.

Even without the consideration of electronic attacks and satellite failures, a much smaller version of this technology could overcome day-to-day problems with regular GPS use. Anyone who has ever used a map application in a city environment has likely experienced blockages from the buildings disrupting satellite signals. A quantum accelerator would calculate its position based on its high precision velocity measurements rather than GPS information, thus eliminating never-ending “recalculating” type errors that current mapping devices are prone to receive.
General accelerometers are already found in common devices like cell phones and video game controllers. Overall, they function by calculating changes in the velocity of an object (phone, controller, etc.) and that data is used for whatever its intended purpose. For location-driven applications, however, the measured position loses accuracy without feedback from external sources such as GPS. For example, after a few street turns (or less), a mapping application would need to confer with a satellite to recalculate the new position of the car in motion. The high precision of a quantum accelerometer does not have this limitation, thus eliminating the need for a GPS signal.
When atoms are cooled to ultra-cold levels, their quantum behavior emerges and can then be measured by a laser beam acting as a ruler. The team behind the quantum accelerometer device had already been developing other commercial quantum technologies prior to the current one, so when the need for arose for measuring and cooling atoms, a solution was already in place via the team’s universal laser system developed for gravity measurements. This laser both cools and measures the atoms involved in the accelerometer’s device’s movement calculations.
This quantum device is representative of the transition of quantum mechanics from the science laboratory to real-world applications. Besides navigational solutions, Professor Ed Hinds, Director of the Centre for Cold Matter at Imperial College London, described gravity measurements, mapping gravitational forces to look for minerals, and looking inside vehicles to diagnose problems as a few suggestions for other applications. “[The potential applications] …all come from the fantastic sensitivity and reliability that you can only get from these quantum systems.”

Tesla just tipped its hand on a major Cybercab feature as production hits Plaid Mode
Tesla has delivered a clear signal that its Robotaxi ambitions are shifting into high gear. On April 17, longtime factory observer and drone pilot Joe Tegtmeyer captured drone footage and still images showing approximately 14 freshly built Cybercabs parked in the outbound lot—each one conspicuously lacking a steering wheel.
Tesla just tipped its hand on a major Cybercab feature as it is putting production into Plaid Mode, but a clear indication of what the company plans to do with the vehicle is now apparent.
Tesla has delivered a clear signal that its Robotaxi ambitions are shifting into high gear, and it’s doing it with full autonomy in mind.
On April 17, longtime factory observer and drone pilot Joe Tegtmeyer captured drone footage and still images showing approximately 14 newly built Cybercabs parked in the outbound lot, each conspicuously lacking a steering wheel, and potentially pedals.
Tegtmeyer’s post highlighted the significance of this development: The images and video reveal sleek, two-seat Cybercabs in their final production form: no driver controls, no side mirrors, and the minimalist interior first unveiled at Tesla’s “We Robot” event in October 2024.
Something big has changed at Giga Texas with Cybercab production … ~ 14 in the outbound lot WITHOUT STEERING WHEELS!
Earlier this week, the production line has begun what we are all waiting for and I would expect to see many more starting on Monday, 4/20 🤠
A big step… pic.twitter.com/K17ZzBlQ8k

These units contrast with earlier test vehicles spotted at the factory’s crash-test area, which carried temporary steering wheels and pedals to meet current federal regulations during data-collection phases.
The outbound-lot vehicles appear complete, with production wheels, tire stickers, and the signature Cybercab styling ready for deployment.
This sighting represents a pivotal transition. Tesla designed the Cybercab from the ground up as a purpose-built robotaxi, engineered for unsupervised Full Self-Driving (FSD) operation. Removing manual controls eliminates cost, complexity, and weight while maximizing interior space and range.
The move also signals that Tesla has cleared initial validation hurdles and is now building vehicles to the exact specification intended for commercial robotaxi service.
Industry watchers note the timing aligns with Tesla’s broader rollout plans. Production of early Cybercabs began in late 2025 and early 2026, primarily for internal testing and regulatory compliance.
Federal Motor Vehicle Safety Standards currently limit vehicles without steering wheels to 2,500 units per year without exemption, a cap that Tesla is navigating through ongoing filings.
Tesla Cybercab spotted next to Model Y shows size comparison
The appearance of steering-wheel-free units in the outbound lot suggests the company is preparing a small initial fleet—likely for Austin pilot operations or further validation—while pushing for regulatory relief to scale output.
The development comes as Tesla ramps its dedicated Cybercab line at Gigafactory Texas. If the Monday surge materializes as predicted, observers expect dozens more units to accumulate rapidly.
With unsupervised FSD advancing and regulatory conversations ongoing, these wheel-less Cybercabs parked under the Texas sun represent more than hardware—they embody Tesla’s bet that autonomous mobility is no longer a prototype dream but an imminent reality.

Tesla preps new Model Y trim for India, a once-elusive market
Tesla’s journey into India began with significant hurdles. For years, the electric vehicle giant faced steep import tariffs ranging from 70 percent to 110 percent on fully built vehicles, which dramatically inflated prices and stalled entry plans.
Tesla is preparing to bring its newest Model Y trim to India, a once-elusive market that was hesitant to allow any vehicles built outside the market into its automotive sector.
Now, it is preparing to allow China-built Model Y vehicles to come into the country, in an effort to expand sales and offer what is a widely-requested variant to Indian customers.
Tesla’s journey into India began with significant hurdles. For years, the electric vehicle giant faced steep import tariffs ranging from 70 percent to 110 percent on fully built vehicles, which dramatically inflated prices and stalled entry plans.
Elon Musk repeatedly criticized these duties as among the world’s highest, making premium EVs like the Model Y prohibitively expensive for most buyers in the price-sensitive market.
After prolonged negotiations and multiple delays, Tesla finally debuted in July 2025 with a quiet rollout focused on luxury segments. It opened showrooms in Mumbai and New Delhi, importing standard Model Y SUVs from its Shanghai Gigafactory.

Yet the launch proved challenging: vehicles carried sticker prices near $70,000, leading to tepid demand. Bloomberg reported only about 600 orders in the first two months, while official data showed just 227 registrations for all of 2025—far below internal targets. By early 2026, the company offered discounts of up to ₹200,000 ($2,200) to clear unsold inventory.
Now, less than a year later, Tesla is demonstrating resilience and adaptability. According to a Bloomberg report on April 17, the company is preparing to launch the Model Y L—a six-seat, long-wheelbase variant with three-row seating—as early as next week.
This marks Tesla’s first new product introduction in India since its initial entry. Notably, the newest Model Y configuration, which debuted in China in 2025 and features extended space tailored for families, will once again be exported directly from Tesla’s Shanghai Gigafactory.
The move highlights a shift from early struggles to a more targeted approach, leveraging an existing platform to better suit Indian preferences for multi-generational, spacious SUVs without committing to immediate local production.
Tesla launches in India with Model Y, showing pricing will be biggest challenge
The Model Y L’s arrival underscores Tesla’s incremental strategy amid global EV headwinds and India’s unique challenges, including limited charging infrastructure and competition from local manufacturers.
While tariffs continue to keep pricing in the premium segment, the six-seater variant aims to broaden appeal beyond early luxury adopters by addressing practical family needs.
This evolution, from battling high barriers and disappointing initial sales to exporting its latest derivative model, signals cautious optimism.
Success with the Model Y L could strengthen Tesla’s foothold in one of the world’s most populous markets and potentially pave the way for deeper investments, such as localized manufacturing, should tariff relief or policy shifts materialize.
For now, the China-to-India supply chain represents a pragmatic bridge over the very obstacles that once made entry so difficult.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.
