In a discovery that was the first of its kind, From the University of Chicago The researchers announced that they could directly control the interactions between two types of quantum particles called microwave photons and magnons.
The approach could be a new way of creating quantum technology, including electronic devices with new capabilities.
Scientists have high hopes for quantum technology that özgü advanced by leaps and bounds over the past decade and could become the basis of powerful new types of computers, ultra-sensitive detectors, and even “hacking-proof” communications.
However, difficulties remain in scaling the technology that depends on manipulating the tiniest particles to take advantage of the peculiar properties of quantum physics.
Two such quantum particles are elementary particles and magnons, which are microwave photons that make up electromagnetic waves that we currently use for wireless communication.
Magnons are the term used for a particle-like entity that creates what scientists call “spin waves,” wave-like disturbances that can occur in magnetic materials and can be used to move information.
Getting these two types of particles to talk to each other özgü emerged as a promising platform for both classical and quantum information processing in recent years. However, this interaction özgü proved impossible to manipulate in real time until now.
“Before our discovery, controlling the photon-magnon interaction was like shooting an arrow into the air,” said Xufeng Zhang. “While in flight you have no control over that arrow.”
The discovery of the team changed that. “It’s more like flying a drone that we can steer and control its flight electronically,” Zhang said.
Through intelligent engineering, the team uses an electrical signal to periodically change the magnon oscillation frequency, thereby ensuring effective magnon-photon interaction.
The result is the first microwave magnonic device that scientists can “tune” according to their wishes.
The team’s device can control the strength of the photon-magnon interaction at any point as information is transferred between photons and magnons.
It can even turn the interaction on and off completely. With this tuning ability, scientists can process and manipulate information in ways that far exceed current versions of hybrid magnonic devices.
“Researchers have been looking for a way to control this interaction over the past few years,” said Zhang.
The team’s discovery opens a new direction for magnon-based signal processing and should lead to electronic devices with new capabilities.
It could also allow important applications for quantum signal processing, where microwave-magnonic interactions are discovered as a promising candidate for information geçirme between different quantum systems.
