Quantum Industries

eleQtron is a German quantum computing hardware company (founded in 2020) specializing in trapped-ion-based technology that uses microwaves, instead of lasers, for qubit control, known as MAGIC (Magnetic Gradient Induced Coupling).

Technology and R&D

• Core Technology: MAGIC (Magnetic Gradient Induced Coupling) — Utilizes magnetic field gradients to induce coupling, enabling quantum gates and entanglement in ion traps using microwaves. This avoids the complexity of aligning multiple high-stability lasers.

• Technological Claim: Compared to laser control, microwave control is "more precise, robust, and scalable"; it facilitates the scaling of qubit numbers using mature microwave technology and miniaturized control electrodes.

▲ The MAGIC (Magnetic Gradient Induced Coupling) technology differs from the laser-addressing control method. The laser-addressing method uses extremely focused, power-stable, and precisely aimed laser beams, which must accurately illuminate a specific ion. If scaling to 1000 ions, 1000 laser beams would be needed with precise alignment, and without "crosstalk" (e.g., beam A accidentally hitting ion B), which is a major obstacle to scalability. MAGIC employs a spatially non-uniform magnetic field (a magnetic gradient), causing atoms at different positions to experience different magnetic fields, resulting in different Zeeman energies (i.e., different natural frequencies). For manipulation, only a "global" microwave field at a specific frequency needs to be applied, which can distinguish between resonant and non-resonant ions to perform operations. This eliminates the complexity of precise lasers. In other words, the traditional laser-addressing method uses "spatial distinction" for addressing, whereas MAGIC uses "frequency distinction" for addressing.
