📚 Academic Research

Quantum-Inspired Optimization through Qudit-Based Imaginary Time Evolution (arxiv:cs). The authors propose a quantum-inspired, qudit-based imaginary-time optimizer for integer combinatorial problems. It cuts variables, enforces constraints naturally, and notably beats Gurobi on Min-d-Cut benchmarks

Exploiting Movable Logical Qubits for Lattice Surgery Compilation (arxiv:cs). This paper introduces lattice-surgery compilation with teleportation-enabled movable logical qubits for two-dimensional color codes. Simulations show substantial circuit-depth reductions, improving scalability of superconducting fault-tolerant architectures

Bridging quantum and classical computing for partial differential equations through multifidelity machine learning (arxiv:cs). They propose a multifidelity framework upgrading coarse quantum PDE simulations to high-accuracy solutions using limited high-fidelity classical data. This bridges hardware limits and scientific workloads

Generative modeling using evolved quantum Boltzmann machines (arxiv:cs). Wilde develops practical training methods for evolved quantum Boltzmann machines performing Born-rule generative modeling of complex probability distributions. Algorithms offer convergence guarantees and hybrid optimization

Adversarial Limits of Quantum Certification: When Eve Defeats Detection (arxiv:cs). Eve-GAN, a generative adversarial network, learns classical correlations statistically indistinguishable from quantum statistics in Bell-type experiments. It reveals certification limits and methodological pitfalls in QKD

👋 Before you go...

I've got a big favor to ask - keeping Blaze running isn't expensive, but it does all add up, so I'm asking readers like you to help, if you can, by joining the Patreon page. Nothing flashy, just a way for folks who find value in these newsletters to chip in a little each month.

If you are getting value from blaze, checking this out would mean the absolute world. But if you can't contribute, no worries - the newsletters keep coming either way. Thanks for reading and being part of this nerdy corner of the internet. All the best for the coming week - Alastair.
