Mitsubishi Electric Corporation and Nanofiber Quantum Technologies Inc. NanoQT has announced that they are starting a joint project. This project will focus on creating interconnection technologies for neutral-atom quantum computers.
Neutral-atom quantum computers stand out for their scalability. This is thanks to high integration and flexible control of atomic setups with optical tweezers. Even with these strengths, the number of qubits in one system is still limited. This is mainly because there isn’t enough space to place the atoms. To make large-scale quantum computing practical, we need to connect multiple quantum computers. This will increase the total number of usable qubits.
In this project, the two companies want to create a photonic quantum interface. They will combine Mitsubishi Electric’s qubit control technologies with Nanofiber Quantum Technology’s unique technology. This technology uses ytterbium (Yb) atoms and nanofiber cavities. The goal of this collaboration is to show a high-efficiency link between quantum computers that use neutral Yb atoms.

The key to this effort is making an atom-photon interface. This interface improves atom-photon interactions with nanofiber cavities. This improvement should greatly boost how we create quantum entanglement. This entanglement is vital for communication between quantum systems. Also, by storing several Yb atoms in the nanofiber cavities, the project will look into sharing entanglement in parallel.
Mitsubishi Electric Corporation’s qubit control skills will help connect quantum computers. These innovations are expected to enable fast and high-capacity communication between them.
