# An expert predicts the arrival of a quantum computer with 50 logical qubits within 5 years

In the next five years, quantum computers with 50 logical qubits will emerge. This was stated by Sebastian Hassing, host of The New Quantum Era podcast and author of the book of the same name.

He believes this will be a "point of no return," after which classical simulation methods will become ineffective.

Hassing shared this forecast during a special episode of Quantum Computing Report in a conversation with QuEra Computing's Chief Commercial Officer Yuval Boger. The expert, who worked for about 10 years at IBM Quantum and AWS, focused on his own consulting project, The New Quantum Era, in early 2026.

According to Hassing’s assessment, the technology development roadmap will look as follows:

• short-term outlook: advantage of neutral atom systems;
• medium-term outlook: dominance of superconducting qubits;
• long-term outlook: emergence of spin and photonic solutions.

Hassing noted that platforms based on neutral atoms demonstrate excellent scaling and error correction implementation (LDPC codes), but their "Achilles' heel" remains low operational clock speeds compared to superconducting systems.

Boger called his colleague’s forecast "conservative," recalling recent successes by Harvard and QuEra in demonstrating 48 logical qubits. He cited the opinion of QuEra’s CTO, Vladan Vuletic, who increased his confidence horizon in neutral atom leadership from five to ten years.

Boger also emphasized that, thanks to new algorithms and memory efficiency (where the ratio of physical to logical qubits can reach nearly 2:1), the industry will not need millions of physical qubits to achieve practical supremacy.

Recall that in May, Quantum Machines announced a median two-qubit operation fidelity of 99.5% on the commercial superconducting processor Novera from Rigetti.

On June 1, D-Wave Quantum revealed plans to create a fault-tolerant quantum computer with 100 logical qubits by 2032.
