1+ day, 17+ hour ago   (387+ words) Across instances ranging from 2^7 to 2^(12) cars, their XQAOA 1 algorithm achieved an average paint-swap ratio of 0.357, consistently outperforming four classical heuristics, including the recently proposed Recursive Star Greedy. This work marks the first report of size-dependent performance degradation of Recursive QAOA…...

1+ week, 13+ hour ago   (1047+ words) Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to…...

1+ week, 1+ day ago   (875+ words) The Quant possesses over two decades of experience in start-up ventures and financial arenas, brings a unique and insightful perspective to the quantum computing sector. This extensive background combines the agility and innovation typical of start-up environments with the rigor…...

1+ week, 1+ day ago   (584+ words) How an AI auto-tuned amplifier could speed up quantum computing and dark matter experiments. Physicist Christian Boutan works on a dilution refrigerator used to cool quantum devices to a temperature near absolute zero. Quantum amplifiers must be tuned to operate…...

1+ week, 3+ day ago   (341+ words) The LRU operates concurrently with transmon measurement without adding to processing time, using a protocol adapted from double-drive reset of population (DDROP). This involves simultaneous drives applied to both the transmon qubit and its readout resonator, using the dispersive shift…...
