QuEra Predictions for 2025
Magic state distillation is a crucial process for performing universal fault-tolerant quantum computing. In this work, QuEra’s team demonstrates the power of its new Gemini-class device by showcasing magic state distillation with logical qubits. The experiments showcase the encoding of quantum information in distance-3 and distance-5 color codes, the injection of magic states into those logical qubits, and a subsequent 5-to-1 distillation process, which improves the logical fidelity of the states.

Alongside the recent excitement around logical gate-based computing with neutral atoms, analog computing remains an active area of development. In this work, the JPMorgan and AWS teams have partnered to develop compilation pipelines for optimization problems, introduce a method to quantify the onset of hard optimization problem instances, and demonstrate their tools’ functionality on QuEra’s Aquila.

Scaling up the number of qubits in quantum computers remains a central goal of the entire community. In this work, the authors leverage an AI-enhanced protocol to assemble defect-free neutral atom arrays with over 2,000 atoms in a constant time of 60 ms, using high-speed spatial light modulators. These results are expected to enhance the short-term scalability of neutral-atom hardware, both in absolute terms and in combination with future techniques for continuous atom reloading.

Chemistry simulations are widely accepted as a key application for quantum computing. A major challenge, however, is that the electronic structure at the heart of chemical reactions is not naturally suited for qubit-based representation. This results in a typically large overhead, limiting the potential advantage of quantum-enhanced pipelines.In this work, Phasecraft’s team introduces a novel encoding methodology that promises to outperform existing methods in both qubit ratio and reducing the weight of the encoded Pauli operators. It will be exciting to see how these results impact near-term simulations in chemistry and materials science.
