In this post, I want to unpack a topic that keeps coming back in discussions about modular quantum architectures: how can I get really good multi-partite entanglement between remote modules without drowning myself in slow, error-prone two-qubit gates on memories?
Read MoreWhen I first encountered the term "fault-tolerant" in quantum computing literature, I noticed something puzzling: different researchers seemed to be using it in subtly different ways. In this blog post, I'll walk through the various contexts and definitions of fault-tolerance that have emerged in our quantum computing community.
Read MorePhantom codes implement logical CNOT entangling gates using only classical qubit relabelling, achieving zero overhead and perfect fidelity. By placing logical operations at the center of code design, we achieve fault-tolerant entanglement at no physical cost.
Read MoreThreshold is one of the most frequently cited concepts in quantum error correction, yet it means different things in different contexts. This article unpacks the various thresholds, explains how they are calculated, and provides practical guidance for interpreting them in the lab.
Read MoreA deep dive into why one giant quantum computer won't work—and why breaking it apart changes everything about how we build scalable, fault-tolerant quantum systems.
Read MoreDiscover how monolithic surface code circuits can be transformed into fault-tolerant distributed architectures through the power of multipartite GHZ states. This blog explores the mathematical foundation and practical implications of this transformation for scaling quantum computers with modular hardware.
