Pushing the boundaries of Quantum Computing

In this insightful conversation, Dr. Pedram Roushan, Staff Research Scientist at Google Quantum AI, joins Michaela, PhD physicist at Quantum Machines, to explore the frontier of quantum simulation on today’s hardware, without relying on fault tolerance.

Dr. Roushan walks us through how high-quality qubits, even without full error correction, can already address complex problems in non-equilibrium dynamics, solid-state physics, and lattice gauge models. Instead of waiting for fully fault-tolerant systems, his team is pushing the limits of what’s possible right now, using devices with error rates around 10⁻³ to 10⁻⁴.

He also shares how Quantum Machines’ low-latency control systems are enabling new algorithmic possibilities by creating artificial connectivity between distant qubits in 2D arrays. By leveraging measurement-based conditional logic, Google’s team can simulate long-range interactions without physically wiring qubits together, which is critical for scalable architectures.

Key topics discussed:

– Useful physics problems that can be tackled today without error correction

– The role of coherence, qubit quality, and algorithm design in pushing classical-quantum boundaries

– How artificial connectivity and real-time feedback from Quantum Machines’ control stack enable new experimental protocols

– The shift from academic curiosity to practical implementation and how the community is evolving

Dr. Pedram also gives us a glimpse into the near future, where quantum processors with 50+ high-fidelity qubits may routinely outperform classical systems on targeted simulations.

This is a must-watch for researchers and engineers looking to stay ahead of where quantum hardware is going and what it can already do today.
