A superior Cobb Salad at the Wooden Spoon in SF. Good ingredients, particularly the maple syrup bacon. But also they tossed the greens with the dressing and then arranged the parts on top. This is the right way to make a salade composée but so many American places give you the dressing on the side. What am I supposed to do, toss it at the table?!

Non-Clifford Gates are Required for Long-Term Memory
We show that all Clifford circuits under interspersed depolarizing noise lose memory of their input exponentially quickly, even when given access to a constant supply of fresh qubits in arbitrary states. This is somewhat surprising given the result of Aharonov et al. [STOC1997] which gives a fault-tolerant protocol for general quantum circuits using a supply of fresh qubits. Our result shows that such a protocol is impossible using only Clifford gates demonstrating that non-Clifford gates are f…

Thank you for your counselling in my moment of consumer crisis. Order placed! Now I have to deal with the fact modern phones are designed to be impossible to hold securely in your hand. That beautiful glass and aluminum in the product shot is about to be swaddled in cheap TPU.

Digital Signal Processing from Classical Coherent Systems to Continuous-Variable QKD: A Review of Cross-Domain Techniques, Applications, and Challenges
This systematic review investigates the application of digital signal processing (DSP) techniques -- originally developed for coherent optical communication systems to continuous-variable quantum key distribution (CV-QKD). The convergence of these domains has enabled significant advances in CV-QKD performance, particularly in phase synchronization, polarization tracking, and excess noise mitigation. To provide a comprehensive and reproducible synthesis of this emerging field, we employed the AP…
