A team of Stony Brook University physicists and their collaborators have taken a significant step toward the building of a quantum internet testbed by demonstrating a foundational quantum network measurement that employs room-temperature quantum memories. Their findings are described in a paper published in the Nature journal Quantum Information.

Research with quantum computing and quantum networks is taking place around the world in the hopes of developing a quantum internet, a network of quantum computers, sensors, and communication devices that will create, process, and transmit quantum states and entanglement. It is anticipated to enhance society’s internet system and provide certain services and securities that the current internet does not have.

The field of quantum information combines aspects of physics, mathematics, and classical computing to use quantum mechanics to solve complex problems much faster than classical computing and to transmit information in an unhackable manner. While the vision of a quantum internet system is growing and the field has seen a surge in interest from researchers and the public at large, accompanied by a steep increase in the capital invested, an actual quantum internet prototype has not been built.

The next generation of wireless communication not only requires greater bandwidth at higher frequencies – it also needs a little extra time.

Cornell researchers have developed a semiconductor chip that adds a necessary time delay so signals sent across multiple arrays can align at a single point in space, and without disintegrating. The approach will enable ever-smaller devices to operate at the higher frequencies needed for future 6G communication technology.

Superconducting circuits, which conduct electricity without resistance, are among the most promising technologies for quantum computing and ultrafast logic circuits. However, finding a practical way to work with these materials that require extremely cold temperatures has been a challenge.

In a step toward that goal, a team of researchers led by Prof. Hong Tang developed and successfully demonstrated a device that presents a viable solution in transferring a very weak signal from a computing device stored at cryogenic temperatures to room temperature electronics to achieve a fast data transfer with very low energy consumption. The results are published in Nature Photonics.

The practical use of superconducting circuits requires connecting them to room temperature electronics. But doing so has largely relied on coaxial cables, which have a limited bandwidth and limited thermal conductivity – two factors that negate the benefits of superconducting circuits.
