Quantum Breakthrough: Scientists Create Schrödinger-Cat State With Record-Long Lifetime

USTC researchers created a long-lived Schrödinger-cat state, boosting quantum metrology and precision measurements. Their findings open new possibilities for quantum computing and fundamental physics.

A research team led by Prof. Zhengtian Lu and Researcher Tian Xia from the University of Science and Technology of China (USTC) has successfully created a quantum state with a lifetime on the scale of minutes using optically trapped cold atoms. This breakthrough significantly improves the sensitivity of quantum metrology measurements. Their findings were published in Nature Photonics.

In quantum metrology, particle spin serves as a powerful tool for measuring magnetic fields, inertia, and various physical phenomena. It also has the potential to uncover new physics beyond the Standard Model. A high-spin Schrödinger-cat state, a superposition of two maximally opposed spin states, offers unique advantages for precision spin measurements.

First Humanoid Race in China

 A one-of-a-kind event is fast approaching in southeast Beijing’s Economic-Technological Development Area (often called “Beijing E-Town”). Slated for April 13, this half-marathon will see humans and humanoid robots compete on the same 21km route.


As registrations begin on March 5, global anticipation is quickly mounting. While the basic format has been public knowledge for some time, newly released rules give a clearer picture of the event and its stakes.


Additionally, recent announcements of more than 10,000 robot placements in key industries amidst the marathon preparations suggest something far larger is at stake for China’s robotics sector.

Extended competition rules
For the robot category, organizers have set a cutoff completion time of roughly 3 hours and 30 minutes. Unlike human runners, robot teams can switch batteries mid-race or swap out their robots in a relay setup. Each change, however, comes with a 10-minute penalty added to the team’s final time.     READ MORE...

China Outnumbers US

After being overtaken by China in naval strength, a senior US military official has now warned that by 2027, China’s modern fighter jet fleet will outnumber US forces about 12 to 1 in key regions of the Western Pacific.

Brigadier General Doug Wickert, commander of the 412th Test Wing at Edwards Air Force Base, shared the information regarding the anticipated dominance of Chinese aerial power during the Back-in-the-Saddle Day event on January 6.

The US Air Force General stated that the speed at which China is modernizing its military is “unprecedented,” further noting that it is “far outpacing” comparable modernization efforts by the United States.

The warning follows the PLA’s introduction of two new combat aircraft on December 26, touted as sixth-generation fighter jets, to celebrate Chinese Communist Party founder Mao Zedong’s birthday.     READ MORE...

China's Mars Mission Leaves US Behind

Hong Kong CNN — China’s historic attempt to bring samples from Mars to Earth could launch as soon as 2028, two years earlier than previously stated, according to a senior mission official.

The country’s Tianwen-3 mission would carry out two launches “around 2028” to retrieve the Martian samples, chief mission designer Liu Jizhong said at a deep-space exploration event in eastern China’s Anhui province last week.

The projected mission launch is more ambitious than a 2030 target announced by space officials earlier this year, though the timeline has fluctuated in recent years. A 2028 target appears to return to a launch plan described in 2022 by a senior scientist involved with the Tianwen program – a mission profile that would see samples returned to Earth by 2031.    READ MORE...

China's Supersonic Jet

CHINA is vying to take on the 'Son of Concorde' with an even faster supersonic jet that could blast from London to New York City in less than two hours.

Beijing-based Space Transportation - also known as Lingkong Tianxing Technology - has been carrying out test flights and recently reached a speed of 3,106 mph which is four times the speed of sound, according to Chinese media.

The so-called Jindouyun engine, or JinDou400, could enable travel twice as fast as the iconic Concorde.  In the latest test it was able to reach altitudes over 65,600 feet, the company claims.

It achieved this by doing away with compressors and turbine parts you find in most rocket engines, relying on detonation combustion technology instead.  This tech uses a detonation ramjet to create essential thrust.     READ MORE...

Air Engine Created

Why do countries launch so many rockets into space? It’s not just for exploration or for taking pictures of the moon and stars. You rely on satellites that orbit the Earth for almost every aspect of your daily life. You get directions from GPS signals that ping from satellites, and your cellphone sends and receives messages that way too. By launching a rocket with an engine fueled by methane and oxygen, China will be able to send rockets into Earth’s orbit at 18,000 miles per hour without refueling.

A new type of rocket fuel could launch China farther into space, beating its competition by a million miles
China has announced the successful launch of ZQ-2 Y2, the nickname of the country’s first liquid methane and liquid oxygen-fueled spacecraft. American scientists are worried about catching up to this breakthrough in aerospace engineering. Chinese companies and government organizations work hard to be at the forefront of technological innovation, and this event proves that their efforts pay off. Using this ne, ZQ-2w fuel, China could save millions of dollars and reduce some of the emissions created when launching rockets.

Liquid methane and liquid oxygen are not easy to create. To turn these gases into liquids, scientists have to force them through metal tubes submerged in super-cold liquid nitrogen. The freezing temperature slows down the gas particles, turning the substance into a liquid. Liquid methane and liquid oxygen burn much cleaner than traditional rocket fuel, which is made from petroleum.      READ MORE...

First Artificial Sun

The Huanliu-3, or the HL-3 “Artificial Sun” in China, is thriving in fusion energy research with its new experiments. What is more exciting is the use of a digital twin system, which is a sophisticated virtual technology that offers real-time tracking and could be the holy grail in furthering controlled nuclear fusion.

Understanding solar energy: The contribution of HL-3 in the sustainable energy evolution
The HL-3 is the most sophisticated magnetic containment nuclear fusion research facility in China and throughout the world. It was created and manufactured by the China National Nuclear Corporation (CNNC) on plant engineering level and is intended to reproduce nuclear fusion processes like those found in the sun where inexhaustible amounts of energy is released when hydrogen atoms fuse together.

Although still in the works, HL-3 is also a leap towards developing a sustainable and clean source of energy. The operation of HL-3 is further improved through the integration of digital twin system, which is referred to as ‘super eye’ of critical processes.

This technology provides real time control of the system’s vacuum chamber whilst the latter is in its baking process, a feat that considerably increases safety and management control. Nuclear reactor in vacuum containment is critical to the nuclear fusion process since it provides the required conditions for the formation of plasma, which is a crucial state of matter for fusion enhancement reactions.  READ MORE...

Artificial Intelligence and Fusion Reactors

Scientists in China achieved a major breakthrough that could help unlock nearly unlimited clean energy via fusion.


They hope to do so by solving one of the biggest challenges for fusion reactors, as Interesting Engineering explained. That is the puzzle of measuring the ultrahot plasma, which creates fusion reactions quickly and accurately in real time. Having faster data will help optimize fusion performance and maintain reactor stability.


The research team from the Hefei Institutes of Physical Science used neural networks powered by artificial intelligence. Neural networks leverage pattern recognition and advanced calculation abilities that allow them to quickly generate measurements, per Interesting Engineering.


The scientists enlisted two neural network models to measure two critical parameters of the plasma: ion temperature and rotation velocity. The results were impressive and bode well for future applications to harness fusion power.          READ MORE...

Toroidal Electromagnetic Pulses

Toroidal electromagnetic pulses can be generated using a device known as a horn microwave antenna. 

This electromagnetic “vortex cannon” produces skyrmion topological structures that might be employed for information encoding or for probing the dynamics of light–matter interactions, according to its developers in China, Singapore and the UK.

Examples of toroidal or doughnut-like topology abound in physics – in objects such as Mobius strips and Klein bottles, for example. It is also seen in simpler structures like smoke rings in air and vortex rings in water, as well as in nuclear currents. 

Until now, however, no one had succeeded in directly generating this topology in electromagnetic waves.     READ MORE...

Quantum Time Flip

It’s been 35 years since Cher first wanted to turn back time, but it turns out that quantum mechanics might have allowed for this wild reversal all along. In new research, scientists from China and Hong Kong show that—in certain quantum systems—the time variable can be reversed by creating a double superposition (one each in opposite directions) and still bear out valid results. 

What results from this little bit of quantum trickery is both an input and output that are considered indefinite, meaning that either one can be the input or the output. Basically, the after can go before the before. The peer-reviewed research appears in the journal Physical Review Letters.

In our day-to-day lives, we perceive time as marching inexorably forward, and that means many processes aren’t easily reversible. You can’t put the toothpaste back in the tube, so to speak—it’s a lot more difficult to reset an object back to its original state than it is to change it in the first place. This is called time’s arrow, and we believe it’s partly caused by the fact that our universe has been ever-expanding since the Big Bang.     READ MORE...
