Google has announced the development of Willow, a state-of-the-art quantum chip that demonstrates error correction and performance capabilities that pave the way for a useful, large-scale quantum computer, according to the search giant. The chip, which boasts 105 qubits, has achieved best-in-class performance in both quantum error correction and random circuit sampling.

"Introducing Willow, our new state-of-the-art quantum computing chip with a breakthrough that can reduce errors exponentially as we scale up using more qubits, cracking a 30-year challenge in the field," Google chief Sundar Pichai wrote on X, Monday. "In benchmark tests, Willow solved a standard computation in <5 mins that would take a leading supercomputer over 10^25 years, far beyond the age of the universe(!)."

Willow shows an impressive performance on the random circuit sampling (RCS) benchmark, completing a computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion years. This achievement demonstrates the exponential suppression of errors, a significant milestone in the development of practical quantum computers.

The chip improves on its predecessor, Sycamore, in three key ways: it has more physical qubits, improved individual qubit quality, and refined fabrication processes. These advancements enable the chip to maintain its delicate quantum state five times as long and have lower error rates.

"Errors are one of the greatest challenges in quantum computing, since qubits, the units of computation in quantum computers, have a tendency to rapidly exchange information with their environment, making it difficult to protect the information needed to complete a computation," Google writes in a blog post announcing Willow. "Typically the more qubits you use, the more errors will occur, and the system becomes classical."

The company continues, "We tested ever-larger arrays of physical qubits, scaling up from a grid of 3x3 encoded qubits, to a grid of 5x5, to a grid of 7x7 — and each time, using our latest advances in quantum error correction, we were able to cut the error rate in half. In other words, we achieved an exponential reduction in the error rate. This historic accomplishment is known in the field as “below threshold” — being able to drive errors down while scaling up the number of qubits. You must demonstrate being below threshold to show real progress on error correction, and this has been an outstanding challenge since quantum error correction was introduced by Peter Shor in 1995."

The development of Willow marks a significant step towards the creation of a useful, large-scale quantum computer that can harness quantum mechanics to benefit society. Google’s advancements in quantum computing have the potential to tackle some of society’s greatest challenges.

"We see Willow as an important step in our journey to build a useful quantum computer with practical applications in areas like drug discovery, fusion energy, battery design + more," Pichai added on X.

 

 

Google's Willow Sparks Concerns Over Impact Of Quantum Computing On Bitcoin Encryption

Meanwhile the crypto community on social media is abuzz with concerns over the impact of quantum computing with chips like Willow, on the Bitcoin network encryption.

However, Bitcoin's cryptographic algorithms -- like the Elliptic Curve Digital Signature Algorithm (ECDSA) for signatures and SHA-256 for mining, -- require millions, if not billions, of qubits to be effectively compromised by quantum computing.

Breaking Bitcoin's encryption in a feasible timeframe would necessitate a quantum computer with approximately 13 million to 1.9 billion qubits, significantly more than Willow's 105 qubits.

While Willow is still considered experimental and far from the scale needed to pose an immediate threat to Bitcoin's security, the crypto community and developers are already working on future quantum-resistant solutions.

There is consensus that any real threat from quantum computing to Bitcoin's encryption is likely years, if not decades, away. This gives ample time for the implementation of new cryptographic methods or protocol upgrades, like soft forks, to enhance Bitcoin's security against future quantum computing advancements.

MMX: Japan Launches Historic Mission To Return Mars Moon Phobos' Sample

Japan Aerospace Exploration Agency, JAXA's H3-24L rocket launched the Martian Moons eXploration (MMX) mission on Monday (Oct. 19), at 1941 UTC, from Pad-2 at the Yoshinobu Launch Complex within the Tanegashima Space Center. The mission aims to become the first to return samples from Phobos, Mars’s larger moon, with a targeted Earth return in 2031.

This was the 10th liftoff of Japan's expendable, two-stage H3 rocket (flight H3 F10), which was jointly developed by JAXA and Mitsubishi Heavy Industries. After clearing its launch pad today, the 63-meter rocket flew a nominal trajectory through its ascent corridor over the Pacific Ocean, jettisoning its four solid boosters in pairs just before the flight clock reached two minutes. The launch vehicle shed its payload fairings about one minute and 20 seconds later, exposing MMX to the vacuum of space for the first time.

H3's first stage, powered by two LE-9 rocket engines, channels a mixture of liquid hydrogen and liquid oxygen to produce a combined thrust of 331,000 pounds (1,471 kN), according to Mitsubishi Heavy Industries. As the mission clock approached T+5 minutes, H3 executed its main engine cutoff procedure and separated from the second stage, which ignited its engines for a 5.5-minute burn about 10 seconds later.

All continued to go to plan after that. The H3's upper stage ignited its engine for a second time for a trans-Mars injection burn about one hour and four minutes after liftoff, a maneuver that lasted roughly six minutes and 25 seconds and took MMX to a maximum velocity of about 38,858 kilometers per hour(kph).

MMX was released from the rocket's upper stage right on schedule, about one minute after the completion of that burn and roughly 71 minutes after liftoff. The success elicited loud cheers in mission control, which viewers saw and heard on JAXA's launch webcast.

The spacecraft is now under its own power, and on course for Mars. The interplanetary transit will last about 10 months, with the spacecraft scheduled to arrive at the Red Planet in August 2027. When it does, MMX's propulsion module will execute an orbital insertion burn to place itself in a quasi-satellite orbit (QSO) around Phobos, which places MMX within the space around the moon as both circle Mars.

The primary goal of MMX is to collect at least 10 grams of Phobos regolith to determine if the Martian moons are captured asteroids or formed from debris ejected by an ancient impact on Mars. The mission will also conduct flybys of the smaller moon, Deimos, and study Mars itself to understand the early solar system's evolution. The spacecraft carries 13 scientific instruments, including MEGANE (developed with NASA) to measure elemental composition via gamma rays and neutrons, and MIRS for infrared mineral analysis.

Led by JAXA with contributions from NASA, ESA, CNES (France), and DLR (Germany), the ~4,480 kilogram spacecraft consists of propulsion, exploration, and return modules. Key components include the Idefix rover (developed by France and Germany) for surface reconnaissance and a lander equipped with both a coring sampler and a pneumatic surface sampler.

NASA has also invested about $87 million through the end of the mission, which includes funding for United States scientists and astromaterials experts on the MMX team. At least 15% of the planned 10-gram (0.35 ounces) returned Phobos sample will be reserved for NASA's study. Those materials will be transferred and maintained at the agency's Johnson Space Center in Houston for analysis and long-term preservation.

MMX is not the first Phobos sample-return project to take flight. That distinction goes to Russia's Phobos-Grunt ("Phobos-Soil") mission, which launched in November 2011 but failed to get out of Earth orbit due to a rocket glitch. The 14.5-ton spacecraft eventually crashed back to Earth over the Pacific Ocean in January 2012.

France Riots: Europe Burns As Rioters Wreck Havoc Over Economic Woes, Failed Policies

The historic Limoges Town Hall, built in 1883 and designated a landmark in 1975, was "largely lost" after masked protesters forced entry and set it ablaze on Saturday. The fire caused the roof and spire to collapse, destroying two-thirds of the exterior; the building had previously survived both World Wars and served briefly as the seat of the Belgian government-in-exile in 1940.

France’s nationwide unrest stems from weeks of student protests over deteriorating school conditions, which expanded into mass demonstrations against rising living costs and fuel prices. The country experienced some of the worst street violence it has seen in decades, drawing together a volatile mix of secondary school and university students, former "Yellow Vests," climate activists, farmers, and opportunistic groups.

On Saturday, an estimated 550,000 to 800,000 people took to the streets, with violence erupting in cities including Paris, Marseille, Lyon, and Lille.

About 1,200 to 2,000 people were arrested, over 150 police officers were injured, and widespread looting targeted shops and public buildings. In Saint-Étienne, a 17-year-old protester suffered severe injuries (losing a hand) after a police-deployed grenade detonated.

Prime Minister Sébastien Lecornu blamed the violence on "ultra-left" groups and criminals, stating the government would not be intimidated, while Interior Minister Laurent Nuñez reported that rioters had the "sole objective to burn, break and loot." President Emmanuel Macron strongly condemned the violence, vandalism, and attacks on public buildings, vowing that perpetrators would be prosecuted.

Unrest also spread to other European nations, driven by similar economic grievances. While France saw the most catastrophic structural damage, smaller or parallel protests and riots broke out in several other European countries over economic pressures and localized grievances.

In Italy, Portugal, and Belgium, Student and public groups marched against household budget constraints, housing costs, and education affordability, though reports indicate these demonstrations were less violent than those in France and Albania.

In Italy, rallies over the cost of living in cities like Milan and Bologna turned violent. Demonstrators clashed with police, forcing the temporary closure of transit hubs like the Duomo metro station in Milan and causing dozens of injuries and detentions among law enforcement and protesters.

In Liège, Belgium, demonstrations over economic strains escalated into property damage and clashes, resulting in dozens of arrests—including minors.

In Portugal, thousands marched in Lisbon over low wages, skyrocketing rents, and a severe housing shortage, setting up protest tents in Rossio square.

Student-led protests in Tirana, Albania, took on an explicitly anti-government tone, entering their fifth consecutive day of fierce clashes. Beyond standard demands for education reform and jobs, protesters called for the resignation of Prime Minister Edi Rama over corruption allegations. 35 people were wounded and 167 arrested.

The protests in Tirana, started with the controversy over a luxury coastal development project linked to an investment firm founded by Jared Kushner (son-in-law of US President Donald Trump). Police deployed water cannons and tear gas against crowds.

Across Western and Southern Europe, persistent inflation, high energy/fuel prices, and stagnant real wages have created deep financial anxiety among working-class families and the younger demographic.

Critics blame left-wing western leaders and their lax immigration and misguided energy policies. The convergence of students, union workers, and disparate political movements highlights a broader breakdown in trust regarding public institutions and the government.

USSF-481: SpaceX Launches Classified Payload To Orbit For The US Space Force

A SpaceX Falcon 9 launched the classified USSF-481 mission from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California, at 0001 UTC on Friday (Oct. 16), carrying a classified payload to a polar low-Earth orbit, for the United States Space Force. The rocket followed a southerly trajectory, reaching a low-Earth orbit inclined approximately 80 degrees to the Equator, a path necessary for polar coverage without overflying populated land.

Vandenberg SLC-4E is the only U.S. launch pad permitting southward polar departure azimuths, making it critical for national security satellites requiring global coverage.

About 8.5 minutes after launch, the first stage booster, B1081 landed on the autonomous droneship Of Course I Still Love You in the Pacific Ocean as scheduled. This recovery marked the 228th booster landing on a droneship and the 671st total Falcon booster landing. This marks the 28th flight for B1081 which has flown previous missions including Crew-7, CRS-29, PACE, Transporter-10, EarthCARE, NROL-186, Transporter-13, TRACERS, NROL-48, COSMO-SkyMed Second Generation FM3, and 16 Starlink deployments.

The USSF-481 mission cargo remains classified, but public notices identify the mission as TH-2 (Task Order 2) under the Space-Based Sensing and Targeting (SBST) contract.

USSF-481 is part of a roughly $1.6 billion Pentagon contract for 18 Falcon 9 launches through the end of 2027, supporting the Proliferated Warfighter Space Architecture (PWSA) and missile-defense initiatives.

Friday's mission wmarks the 114th Falcon 9 launch of 2026, highlighting SpaceX's high-frequency launch rate. The launch was preceded by a formal ceremony at Vandenberg, featuring the five o'clock bugle call "Retreat" and the U.S. National Anthem.
