Russian Achievement: Quantum Computer Supports Scientific Research
Russian Achievement: 70-Qubit Quantum Computer for Researchers
Scientists at the Physics Institute of the Russian Academy of Sciences announced the operation of a quantum computer with 70 qubits, using 35 ytterbium ions and controlling four states for each ion, effectively equaling 70 qubits. This development doubles the conventional capacity of single-ion chain systems, which typically do not exceed 35 qubits.
Operation Accuracy
The single-qubit operation accuracy reached 99.92%, while the two-qubit operation accuracy reached 95.4%, high rates compared to other experimental systems, bringing these quantum computers closer to practical use. The system operates based on collective ion oscillations, with two moving laser beams providing precise individual control of each ion and executing quantum operations accurately.
Qubit Connectivity
The system allows quantum operations between non-adjacent qubits through a “triple-star” connectivity scheme. Scientists successfully ran several notable quantum algorithms, including Grover’s algorithm for database search, the Bernstein-Vazirani algorithm, and prepared a GHZ quantum state.
Practical Applications
This quantum computer is currently available to researchers and developers via a cloud platform, enabling practical tests and the development and refinement of quantum algorithms. This achievement comes amid a global race in quantum computing, where multiple countries aim to advance qubit count and operation accuracy.
