Google's new quantum chip called "Willow" is the revolutionizing tool for quantum computing.


"Willow chip outpaces all known supercomputers, offering insights into future technologies that could change the world". (InterestingEngineering, Google’s new quantum chip ‘Willow’ beats supercomputers by 10 septillion years)

Google describes its new Willow chip like this: 

Google blog says that Willow has state-of-the-art performance across several metrics, enabling two major achievements.

"The first is that Willow can reduce errors exponentially as we scale up using more qubits. This cracks a key challenge in quantum error correction that the field has pursued for almost 30 years. (Google Blog, Meet Willow, our state-of-the-art quantum chip).

"Second, Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion (that is, 1025) years — a number that vastly exceeds the age of the Universe. (Google Blog, Meet Willow, our state-of-the-art quantum chip).

The Willow chip is the size of a Critter chocolate slab. It has 105 qubits. And every single qubit has two states. So. The Willow chip has 2^105 quantum states. And the power of the chip is impressive. The Willow beats supercomputers in 10 septrillion years. That means it makes calculations that supercomputers calculate the rest o of the universe's age in five minutes. 

That means the Willow can be used to break any code on the Earth. It can make impressive simulations and many other things. And maybe quite soon. We will get our first personal quantum computers. The nanotechnology in coolers and pressure systems makes it possible to create small thermos spaces.

Those thermos spaces allow to creation portable combination of high-pressure and low-temperature spaces where superconduction is possible. The combination of high pressure and low temperature would give an impressive opportunity to create small portable quantum computers whose size is the same as traditional servers. The nanotubes or graphene fullerene tubes can support the small metal tubes. That makes those systems quite safe. 

The thing is that the Chinse are made of 504 qubit quantum computers in the Chinese National Computer Institute. And those systems are things that have many civil and military applications. The high-power quantum computers can have much more power than the portable personal quantum computers. Even a small quantum computer can break any code that is made using binary computers. 

One of the things that makes quantum computers problematic is that they are so powerful. Those systems require error detection but they are effective. The multi-state quantum computers that the powerful AI controls can use the acceleration protocol to detect and solve errors. The acceleration model means that the system makes the solution using low speed. When it checks the answer the system accelerates its speed. It can also use two quantum lines or two different quantum computers at the same time. 

The problem with quantum computers is that they need binary computers as the input and output tools. The quantum computer is a tool that can be powerful. However, it requires operating systems and morphing neural networks to drive the programs inside the quantum core. The neural network observes and controls the qubits in the system. 

But when we think of tools like distributing computing we can have more powerful tools that nobody ever imagined. The distributing quantum computers. Networked quantum computers can be the most powerful calculation tool that we ever imagine. This is why. Researchers and developers are working with quantum networks. The quantum networks allow to transmission of data in the form of qubits. 

Or in a long-distance quantum entanglement. That makes it possible for quantum computers can exchange data straight in the quantum mode. That removes the bottleneck of binary computers from communication between systems. When data is once driven to the quantum state next time the system requires a binary state is when the quantum computer delivers processed data to a screen or printer.
