Scientists have found that a method of producing quantum states in ordinary electronics may have broken Moore’s law.

Scientists at the University of Chicago’s Pritzker School of Molecular Engineering have discovered a way to produce quantum states in ordinary everyday electronics. By leveraging the properties of quantum mechanics without the use of exotic materials or devices, this increases the possibility of creating quantum information technology using current devices.

Scientists have found that a method of producing quantum states in ordinary electronics may have broken Moore's law.

For decades, the computer industry has benefited from Moore’s Law, a predictive law that predicts that the number of components that can be accommodated on an integrated circuit will double and performance will double every 18-24 months when prices remain the same. With the development of this situation, computers have evolved from behemoths to micro-devices.

It has also brought us smartphones, the Internet, and a variety of applications that have changed our lives, which can only be called a revolution, but now the “end date” of Moore’s law is thought to be approaching. As small electronic devices approach their physical limits, it becomes more difficult and expensive to produce more advanced chips.

The problem may not be noticed by the average consumer for at least a decade, but at the forefront of computer technology, it has already had an impact. As a result, scientists and engineers are looking for ways to break Moore’s law.

Quantum computing is one of the most promising fields, it is a new computing mode that regulates the calculation of quantum information units according to the laws of quantum mechanics, which is conducive to the use of the special, counterintuitive properties of quantum states, so that information can be stored using qubits (which can be 0, 1 or both).

The problem is that current quantum computing technologies rely on exotic materials such as superconducting metals, suspended atoms or diamonds. Standard electronics is considered too crude to support fine quantum states. But David Awschalom, of the University of Chicago team, found that using silicon carbide could electrically control quantum states.

As an added bonus, the team found that the wavelengths of single photon sequestration emitted by the quantum state of silicon carbide were close to those of the telecommunications band. This means that they can be used not only on fiber optic networks, but can also be used in conjunction with existing electronic devices to create new devices. The team was able to create what Awschalom described as a “quantum FM radio” that transmits quantum information over long distances like a radio.

The team also solved a problem that plagued quantum technology – noise. The team was surprised to find that using diodes effectively releases a quantum signal of noise and makes it almost completely stable.

“This work is a step closer to the realization of systems that can store and distribute quantum information in a global fiber network,” says Awschalom. Such a quantum network would bring a new class of technologies that allow the creation of unbreakable communication channels, the invisible transmission of single electron states, and the implementation of the quantum Internet. “

The study was detailed in two papers published in Science and Progress in Science.
