Михаил Лукин… 51-кубитный квантовый компьютер.

Это СМИ построили заявления о 51 кубитном компьютере Лукина. На самом деле его команда построила не универсальный (цифровой) квантовый компьютер, а аналоговый квантовый симулятор

Although less complex than quantum computers, simulators are still extremely expensive to build, says Devitt, so it’s unlikely that they will find many practical applications beyond physics departments

Rydberg excitation of arrays of neutral atoms is a promising way of studying quantum dynamics and quantum simulations in large systems
We realize a programmable Ising-type quantum spin model with tunable interactions and system sizes of up to 51 qubits. Within this model, we observe phase transitions into spatially ordered states that break various discrete symmetries, verify the high-fidelity preparation of these states and investigate the dynamics across the phase transition in large arrays of atoms
