Shrinking Quantum’s Footprint: Optimizing for Early Fault Tolerance

13.11.2025 by Ray Dalio

The study demonstrates that distillation factories, when applied to $10 \times 10$ Hamiltonians with predefined routing, achieve optimal performance with minimal execution time overhead—specifically, at a repetition rate of $r=10$ for Ising model circuits (1.04$\times$ overhead) and $r=6$ for Fermi–Hubbard model circuits (1.1$\times$ overhead)—confirming the efficacy of this approach for variational quantum algorithms.

New compilation techniques promise to dramatically reduce the resources needed to run practical quantum algorithms on near-term hardware.

Quantum Leap: Teleporting Multi-Qubit States with Greater Efficiency

13.11.2025 by Ray Dalio

A generalized quantum teleportation scheme transmits an unknown n-qubit state by leveraging a partially entangled GHZ channel; Alice performs a projective measurement on her (n+1) qubits and communicates the classical outcome—along with additional state-dependent bits—to Bob, who reconstructs the original state via local X and Z gate operations determined by the received information.

Researchers have developed a new quantum teleportation protocol that improves fidelity and reduces resource demands for transmitting complex quantum information.

Learning to Shield Quantum Bits

12.11.2025 by Ray Dalio

A hierarchical reinforcement learning framework addresses the control of error-corrected quantum systems by operating across multiple timescales—from the rapid analog feedback of individual quantum error correction (QEC) cycles, to the slower digital feedback of logical algorithms, and finally, to a learning loop that optimizes control policies based on accumulated QEC data and estimated error detection rates, effectively adapting to system drift and improving performance over time through iterative policy refinement.

A new reinforcement learning framework autonomously stabilizes quantum error correction by adapting to system drift and maximizing performance.

Mapping Quantum Network Losses with Capacity Limits

12.11.2025 by Ray Dalio

The network’s fidelity degrades predictably with increasing channel error, transitioning from an ideal, noise-free state—indicated by the baseline—to scenarios where all channels experience loss or bit-flip errors, with the most significant performance decline occurring when $QC_3QC_{3}$ exhibits both 30% loss and 30% bit-flip rates, demonstrating a compounding effect of these disturbances.

A novel technique leverages network capacity regions to pinpoint loss probabilities, even amidst noisy channel conditions.
