Phantom 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.
