Physicist Daniel Lidar, a professor at the University of Southern California in Los Angeles, USA, explains the quantum advantage in an article recently published on The Conversation website. The term is generally used as: a point where the field of quantum computing can effectively perform tasks unthinkable for classical computers.
According to Lidar, “quantum computing could one day be as disruptive as the arrival of generative artificial intelligence.” But now this field of study is at a turning point: on the one hand, there are advanced moments when researchers from Google and China have demonstrated the quantum advantage of generating lists of random numbers with certain properties.
On the other hand, The threat of ‘quantum winter’ hangs over this research landscapeThat is, if practical results do not occur in the short term, there will be a decrease in investments. Although the technology industry wants to offer such advantages in the short term, academic research still needs to examine some basic principles before science can become a practical technology.
Where does the power of quantum computing come from?
The fundamental element of quantum computing is the qubit, quantum bit. This unit turns the classical bits on their head, which can only exist in the form 0 or 1. The chameleon-like qubit can exist in multiple states, 0 and 1 at the same time, until it is measured. Naturally, it goes far beyond this and also involves the complex interplay of superposition, interference and entanglement.
This means that quantum computing implements the manipulation of qubits, which can exist in multiple states at the same time (superposition), instantly influence each other (entanglement), and even cancel or strengthen each other. In a confusion that Einstein called “spooky action at a distance”.
Applications of quantum computing
One critical area of current research is machine learning, the development of new algorithms capable of identifying the best places to integrate sensors to capture more meaningful data. Interconnecting quantum computers could be the starting point for a quantum internet with encryption and ultra-secure communication channels.
In this sense, the US National Institute of Standards and Technology (NIST) has already selected four quantum resistant algorithms and will share them globally for use in cryptography. Additionally, quantum computing can help predict the results of complex experiments in chemistry and materials science, accelerating the discovery of new drugs and substances.
Finally, One of the most notable applications of quantum computing is called quantum sensing.It is a device that allows sensitive evaluations in magnetic or electric fields and can detect and measure physical events. Applications cover numerous areas such as environmental monitoring, geological survey, medical imaging and surveillance.
