On 22 October 2025, Google announced that they have solved a real world problem using their Quantum Echoes algorithm that did the work 13,000 times faster than current supercomputers. 

This was the first time it has ever done where they used out of order time correlator OOTC algorithm. This  algorithm is verifiable since it can be ran again and again to get consistent result.

They have released a scientific paper over this where they were able to do study of molecular structure using their latest Willow quantum computing chip. This chip used 105 qubit arrays to simulate the molecular behaviour. In this task, they disturbed one qubit from the simulated structure which lead to the formation of butterfly effect inside kind of like wave. This was first done in forward operations. After this, they ran the same operation but from the reverse side. 

Both the sides waves start interacting with each other and give useful insights about the quantum nature. 

According to Google's team, this method can be used for molecular ruler for getting molecular distances using the data of Nuclear Magnetic Resonance.

This is not the first tine Google has achieved. Earlier in 2019, Google's quantum computer solved a problem which a classical supercomputer could have took thousand years. Also in 2024, it gave solution to how to suppress the errors that took scientists nearly 30 years. 

For future, Google's Quantum team is planing to collaborate with other institutions to solve more real life problems.

How does a NPU, Neural Processing Unit, works? - Science Feed

By
A NPU (Neural Processing Unit), also knows as AI accelerator, is a computing unit specially designed for the running artificial intelligence and machine learning models efficiently and effectively on a single motherboard with other computing units.  There has been significant rise in the use of NPUs in personal devices like smartphones, laptops, PCs etc. to do personalized recommendations and offline AI processing.  NPUs are capable of parallel processing, low precision arithmetic, hardware acceleration.  These have silicon architecture to kind of simulate the human brain working like human where instruction set of AI efficiently ran. NPUs are not for computing traditional problems as it lacks important physical capabilities. Because of these, AI systems are able to learn faster without wasting time and energy. The parallel computation feature give wings to matrix operations ease, activation functions of neural networks, dot product.  NPUs have got dedicated compute ...

What is Dark Energy? - Science Feed

By
There are different forms of energy. But, there has been speculation of an hidden form of energy that has been kind of hiding from us which constitutes a large part of our universe.  The universe has been found to be expanding faster than the speed of light. The traditional form of energy that we have found has been to be not able to provide that much of push. So, there must be something. This type of energy is called Dark Energy. Dark Energy is that form of energy that is not understood by us but it is fundamental in nature and drives the process of the universe. In Theory of General Relativity, there is concept of cosmological constant which says there is a negative of gravitation or empty space that is all over the interstellar space.  The researchers of DES and others have found that the universe is expanding not alone of known form of energy but some mysterious form of it. This is also related to Big Bang. Dark energy is told to be constituent of 68 to 70% of total univer...

How are LIDARs changing field of Robotics - Science Feed

By
In the field of robotics, there is crucial role of sensors out of which the LIDARs (Light Detection and Ranging Sensors) are very important.  LIDAR sensors send the light and detects back the reflected light from any object to estimate how much far away the object is based on the calculations. Laser is used as primary light source as it can bounce back on most surfaces. These are used to make maps of the area where the robot will move around for navigation.  There are different kinds of LIDAR sensors like 1D LIDARs, 2D LIDARs, 3D LIDARs and even 4D LIDARs.  1D LIDARs are most basic type of it because these emit laser in one direction at a time and a point for point cloud is created. A point cloud is a group of large number of points that create map of the area. 1D LIDAR then moves in other direction and make different point after that.  2D LIDARs are the better version of 1D LIDARs as if you are rotating the 1D LIDAR in continuous rotation to project it in a circular...
