Rate 1/2 code, now equipped with fast, parallel, low-space-overhead and symmetrically-addressable surgery gadgets. arxiv.org/abs/2610.06749 Thanks to my amazing collaborators Nishad, Rohan, Varun, Pablo, Misha and Harry @hyharryzhou.bsky.social!

Efficient Logic with Ultra-High-Rate Quantum Codes

Quantum low-density parity-check (qLDPC) codes offer a promising route to reducing the qubit overhead of fault tolerance, with recent ultra-high-rate constructions achieving encoding rates above one h...

@hyharryzhou.bsky.social opening up the first ever QEC course at MIT to a packed classroom. So exciting!!!

Excited to share our paper arxiv.org/abs/2604.16209 on ultra-high-rate codes co-designed for atom arrays! We co-design qLDPC codes with rates around 1/2, showing that they can reach good logical error rates under a circuit-level noise model. This was a fun project with Chen, Nishad, Casey and Andi.

Towards Ultra-High-Rate Quantum Error Correction with Reconfigurable Atom Arrays

Quantum error correction is widely believed to be essential for large-scale quantum computation, but the required qubit overhead remains a central challenge. Quantum low-density parity-check codes can...

From a philosophical perspective, if quantum computing were somehow actually impossible, I think magic state distillation is a likely candidate where issues would appear first. So seeing it work experimentally at all is awesome. ...also I like that one of their circuits is sourced from a tweet.

Our holiday gift this year from QuEra is magic 🪄 We experimentally perform magic state distillation, a key building block of large-scale quantum computers, with distance 3 & 5 logical qubits on our newly built Gemini-class neutral atom computer arxiv.org/abs/2412.15165

Experimental Demonstration of Logical Magic State Distillation

Realizing universal fault-tolerant quantum computation is a key goal in quantum information science. By encoding quantum information into logical qubits utilizing quantum error correcting codes, physi...
