New Technique Paves Way for Hybrid Quantum Networks

April 7, 2025
Prof. Liang Jiang and his postdoctoral associate Zhaoyou Wang at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have developed a new scheme to send quantum information through these transducers. Using their technique, they found they could send a full qubit’s information through a channel, paving the way for hybrid quantum networks. The results were published in Physical Review X.

Some phenomena that occur in materials can be challenging to mimic using quantum computers, leaving gaps in the problems that scientists have explored with quantum hardware. To fill one of these gaps, MIT researchers developed a technique to generate synthetic electromagnetic fields on superconducting quantum processors. The team demonstrated the technique on a processor comprising 16 qubits.

Physicists from the University of Basel have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow superconducting resonator. The results of the experiments and accompanying calculations were recently published in Nature Physics, laying the foundation for the use of coupled Andreev qubits in quantum communication and quantum computing.

In recent theoretical research, a team of physicists, led by University of Rhode Island professor Vanita Srinivasa, envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations.

New Study From Florida State University Has Enhanced Our Understanding of the Single-Electron Solid Neon Qubit

Recently, scientists from Florida State University have studied a new type of quantum bit called an electron-on-solid-neon qubit. The team found that small bumps on the surface of solid neon in the qubit can naturally bind electrons, which creates ring-shaped quantum states of these electrons. When the bumps are a certain size, the electron’s transition energy aligns with the energy of microwave photons. Scientists can utilize this alignment to manipulate electrons in a controlled manipulation.

When was the last time your laptop or cloud storage notified you that it was running low on space? Or you transferred a file only to find out that a bug in the system caused damage, and you could no longer access the information? Data storage, access, and connectivity are important aspects of life in our digital age.
