Simulation Addition: The Theory of Everything
10+ hour, 26+ min ago (289+ words) A simulation theory synthesis by Jeffrey Mulholland. Section 2 — The Bostrom Trilemma Nick Bostrom’s simulation argument frames three possibilities: civilizations go extinct before reaching simulation capability, advanced civilizations choose not to run such simulations, or we are almost certainly living in…...
Chasing Quantum States Through Time: A Tour of Time-Evolution Methods in TensorCircuit-NG
16+ hour, 2+ min ago (1194+ words) Flip a single spin in a spin chain and, at first glance, almost nothing seems to happen. It is just a small disturbance dropped into a large quantum system. But then the disturbance propagates. Magnetization changes. Entanglement grows. Observables evolve....
RIKEN Protein Model Reaches 12,635 Atoms Using Quantum-classical Computing
1+ day, 8+ hour ago (956+ words) Rusty is a quantum science nerd. He's been into academic science all his life, but spent his formative years doing less academic things. Now he turns his attention to write about his passion, the quantum realm. He loves all things…...
Researchers Accelerate Bosonic Quantum Operations by 1000 Times
1+ day, 7+ hour ago (95+ words) ForkLog Researchers Accelerate Bosonic Quantum Operations by 1000 Times Researchers accelerate bosonic quantum operations by 1000 times. Physicists from Chalmers University of Technology have developed a method for performing operations with bosonic quantum codes that reduces their duration from thousands of control…...
Shuttling Electrons Like On A Conveyor Belt Boosts Qubit Performance
1+ day, 8+ hour ago (1358+ 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…...
Bringing classical LDPC code design theory to quantum computers
3+ day, 11+ hour ago (213+ words) Search Science Tokyo site A quantum low-density parity-check (LDPC) code shows a clear threshold phenomenon and strong evidence of a large minimum distance His study is published in the journal Quantum on September 9, 2026. “The quantum constraint is essential, but it…...
Physicists Map When Lost Qubit Coherence Can Come Back to Life
1+ day, 15+ hour ago (581+ words) A quantum bit that has lost its coherence is usually written off as a casualty of its noisy environment, but a new theoretical study argues that this verdict is often premature — and, more importantly, predictable....
Scientists just simulated the “impossible” — fault-tolerant quantum code cracked at last
2+ day, 3+ hour ago (261+ words) Quantum computers have the potential to solve complex problems that no supercomputer today can handle. In the foreseeable future, quantum technology's computing power is expected to revolutionise fundamental ways of solving problems in medicine, energy, encryption, AI, and logistics. "The…...
IBM Nighthawk r2 runs 100,000 quantum circuits per second, hitting a key 2026 roadmap target ahead of schedule
5+ day, 5+ hour ago (463+ words) Nighthawk r2 departs from conventional conditional reset techniques. In previous processor generations, quantum circuits relied on conditional resets using π-pulses and measurement cycles, requiring idle times of hundreds of microseconds between executions to prevent state leakage. Instead, it uses a dissipative…...
1000 Times faster: Swedish breakthrough cuts quantum computer error risks
3+ day, 9+ hour ago (271+ words) A single-period Floquet control method using "quantum lattice gates" to execute operations on bosonic quantum codes over a thousand times faster... Researchers at Chalmers University of Technology, in collaboration with Tianjin University, have developed a single-period Floquet control method using…...
