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

March 8, 2021 by Brian Wang

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

December 13, 2020 by Brian Wang

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

January 2, 2020 by Brian Wang

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 …

Avoiding Numerical Dead Zones to Prevent Quantum Computers Getting Stuck

April 29, 2019April 29, 2019 by Brian Wang

You would want to avoid initializing values that would start in numerical deadzones because then the quantum system would get stuck and would not reach a correct solution.

AI for Good: Balancing the Risks and Rewards #emTechDigital

March 26, 2019March 25, 2019 by Brian Wang

There are series of three speakers talking about using AI for social good, defend human rights and an analysis on how to mitigate AI generated fake news. Ensuring that the era of AI benefits society at large will require developing new ethical principles for the field, and rethinking how we engage with these systems and …

Finalist Quantum Computer Resistant Algorithms Selected in Long Standardization Process

February 5, 2019 by Brian Wang

The National Institute of Standards and Technology is working with many companies and researchers to provide security for financial information and privacy when there are quantum computers powerful enough to break current encryption. They have selected 26 post-quantum algorithms after one year of testing in the second round of a massive selection process. The goal …

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

January 2, 2019January 2, 2019 by Brian Wang

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

October 14, 2017May 20, 2017 by Brian Wang

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

October 15, 2017February 21, 2017 by Brian Wang

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

October 15, 2017January 29, 2017 by Brian Wang

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 …
