Two talks of Alice&Bob QEC team in parallel this morning: @diego-ruiz.bsky.social presented his new results on distillation with biased-noise qubits: with bias=30 he already gets 150x reduction! I talked about implementing rotor codes So many fun subjects to work on, join our team we are hiring!🐱

Playing with hypergraph products and torsion in integer matrices, we get a tiger surface code whose protection against loss and dephasing increases with system size. This tiger surface code cannot be expressed as the concatenation of single-mode bosonic code with a qubit code

Many new folks here, welcome! Let me introduce our new preprint with Yijia Xu, Yixu Wang and @vva.bsky.social on tiger codes 🐅 ! Multimode bosonic codes with low order dissipators and linear photon number constraints that can be measured simultaneously. 📝 arxiv.org/abs/2411.09668

To illustrate how quantum superposition and measurements work one can use a smartphone 📱 and two pairs of 👓 3D glasses 👓 to measure the emitted polarized light in different basis successively. What other simple experiments one can do to illustrate quantum principles ? 🧪⚛️

Does every single post I make appear in the quantum bluesky feed? Here is an apple beautifully colorized by my 4 year old to test.

Interesting quantum architecture paper on the arxiv today! Also with an interesting acknowledgment section 📄 arxiv.org/abs/2311.05605

Acknowledgments section of the paper ending with "live long and prosper"

Hello Bluesky! Here is myself with a giant flower that I saw recently
