Solving 10,000 Year Google Quantum Problem in 5 Days Using 60 GPUs

60 graphical processing units (GPUs) have been used to solve the Google quantum supremacy computer problem. Researchers generated one million correlated bitstrings with some entries fixed, from the Sycamore circuit with 53 qubits and 20 cycles, with linear cross-entropy benchmark (XEB) fidelity equals 0.739, which is much higher than those in Google’s quantum supremacy experiment. …

Breakthrough Electronic Amoeba Analog Computer For Approximate Solving Traveling Salesman Problems

Many important and valuable planning and scheduling problems in logistics and automation are combinatorial optimization problems. The most famous problem of this type is the traveling salesman problem. The salesman problem is this question: “Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits …

Particle Accelerator on a Chip Will Reach a Million Electron Volts by End of 2020

Scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons using an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet. Above – This image, magnified 25,000 times, shows a section of an accelerator-on-a-chip. The gray structures focus infrared laser …

Analog Solver Could Find the Best Solutions to NP-hard Problems.

Zoltan Toroczkai and collaborators have been working toward developing a novel analog mathematical approach that will help advance computation beyond the digital framework. They have a mathematical, analog “solver” that can potentially find the best solution to NP-hard problems. NP-hardness is a theory of computational complexity, with problems that are famous for their difficulty. And …

Simulated Quantum Annealing on regular computers can handle up to a million variable optimization

Supply chain optimization software vendor ServicePower can handle optimizations problems that need to analyze up to 1 million variables. Each variable is represented by a virtual Qubit. They simulate their quantum annealing using parallelization on standard server farms using normal computer hardward to make up for the slower speed compared to D-Wave’s specialized quantum hardware. …

Recipe for room temperature superconductors from California Institute of Technology

Researchers demonstrate that superconductor critical temperature can be raised above room-temperature to ≈ 400K in cuprates by precise control of the spatial separation of dopants. Hence, there still remains substantial “latent” Tc in cuprates. Their proposed doping strategy and superconducting mechanism is not restricted to cuprates and may be exploited in other materials. Their room-temperature …

John Hurt died. He was famous for having chest burst by Alien and as Doctor Who during Dalek Time War

John Hurt, who died on Friday, was a brilliant and versatile actor who made memorable film appearances over five decades. As the subject of the celebrated ‘chestburster’ scene, Hurt is on the receiving end of one of the most played clips ever. The extra dose of chicken giblets and offal that director Ridley Scott used …
