1+ day, 12+ hour ago   (877+ words) Millimetre-scale Penning traps previously relied upon approximations becoming inaccurate as device dimensions shrink. Now, an analytical solution offers precise design choices for optimising planar Penning trap geometry and voltage settings at sub-millimetre scales. This advancement minimises unwanted distortions in confining…...

2+ day, 18+ hour ago   (798+ words) Entanglement, a key resource for future quantum technologies, can surprisingly increase even as systems become noisier. This work reveals that under amplitude damping, the ability to violate fundamental limits of classical physics can initially diminish then reappear with greater decay....

2+ day, 22+ hour ago   (423+ words) The Quantum Mechanic is the journalist who covers quantum computing like a master mechanic diagnosing engine trouble - methodical, skeptical, and completely unimpressed by shiny marketing materials. They're the writer who asks the questions everyone else is afraid to ask: "But…...

2+ day, 22+ hour ago   (1002+ words) Fred is the quantum hardware whisperer who spends their days coaxing million-dollar machines to behave like they're supposed to, instead of acting like very expensive modern art installations. While everyone else debates the philosophical implications of quantum mechanics, Fred's in…...

3+ day, 5+ hour ago   (173+ words) Muhammad Ahsan Shakeel from Management Sciences and colleagues have shown that an amplitude-inspired quantum feature map maintains one hundred per cent test accuracy up to an error probability of 0.10 across depolarizing, bit-flip and phase-flip noise channels. Other tested feature maps…...

5+ day, 9+ hour ago   (516+ 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…...

3+ week, 3+ day ago   (1006+ words) Genuine multipartite entanglement reached its theoretical limit of 1/2 in a two-walker quantum walk, irrespective of initial conditions or coin operator used. This unexpected insensitivity suggests a new level of control over entanglement generation, previously unseen in similar systems. Open boundaries…...
