Russian Scientists Unveil 70-Qubit Quantum Computer

Russian researchers have successfully demonstrated a 70-qubit quantum computer, a significant advancement in quantum technology. Developed at the Lebedev Physical Institute of the Russian Academy of Sciences, the system leverages an ion chain architecture. This unique design allows for precise control and interaction between ions.

The core operating principle relies on collective oscillations of the ion chain. When one ion is affected, the entire chain responds, enabling quantum operations. Developers have enhanced its capability by using dense encoding within four-tier quantum systems, effectively doubling the information stored per ion.

This 70-qubit system boasts high operational accuracy, with single-qubit operations at 99.92% and two-qubit operations at 95.4%. The quantum computer is intended for practical testing and optimization of quantum algorithms, and is already accessible through a cloud platform for computations.
