A new type of quantum computing called boson sampling is capable of calculations that no classical computer could accomplish in any reasonable amount of time. This is the second time a quantum algorithm has claimed to achieve this feat, known as quantum supremacy, after Google made a claim of quantum supremacy using its Sycamore device in 2019.

Boson sampling relies on a strange quantum property of photons – particles of light – that is displayed when they travel through a beam splitter, which splits a single beam of light into two beams propagating in different directions. If two identical photons hit the beam splitter at exactly the same time, they will not split from one another, instead they stick together and both travel in the same direction.

If you shoot many photons through

Light-based Quantum Computer Exceeds Fastest Classical Supercomputers

For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers.

Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum computer, named Jiŭzhāng. The result, reported in the journal Science, was 76 detected photons—far above and beyond the previous record of five detected photons and the capabilities of classical supercomputers.

Unlike a traditional computer built from silicon processors, Jiŭzhāngis an elaborate tabletop setup of lasers, mirrors, prisms and photon detectors. It is not a universal computer that could one day send e-mails or store files, but it does demonstrate the potential of quantum computing.

Last year, Google captured headlines when its quantum computer Sycamore took roughly three minutes to do what would take a supercomputer three days (or 10,000 years, depending

Intel upgrades quantum computer ambitions with new control chip

Intel unveiled on Thursday its Horse Ridge 2 processor for controlling quantum computers, an important milestone in making the potentially revolutionary machines practical.

Intel’s Horse Ridge 2 chip, packaged in this metal housing, is designed to simplify communications between a quantum processor and conventional computers.


The Horse Ridge 2 isn’t a quantum processor itself but is designed to solve the challenges of communicating with future quantum processors with thousands or more qubits. The processor is the second generation of a family that debuted in 2019.

The processor comes as Intel endeavors to catch up with quantum computer rivals like IBM and Google. The chipmaker hopes it eventually will leapfrog the competition with processors housing vastly more qubits, the data processing element fundamental to quantum computers, than its competitors have. Horse Ridge 2 moves Intel closer to that goal by making Intel’s large-qubit-count designs more workable.

Light-based quantum computer Jiuzhang achieves quantum supremacy

A new type of quantum computer has proven that it can reign supreme, too.

A photonic quantum computer, which harnesses particles of light, or photons, performed a calculation that’s impossible for a conventional computer, researchers in China report online December 3 in Science. That milestone, known as quantum supremacy, has been met only once before, in 2019 by Google’s quantum computer (SN: 10/23/19). Google’s computer, however, is based on superconducting materials, not photons.

“This is the first independent confirmation of Google’s claim that you really can achieve quantum supremacy,” says theoretical computer scientist Scott Aaronson of the University of Texas at Austin. “That’s exciting.”

Named Jiuzhang after an ancient Chinese mathematical text, the new quantum computer can perform a calculation in 200 seconds that would take more than half a billion years on the world’s fastest non-quantum, or classical, computer.

“My first impression was, ‘wow,’” says quantum

Supreme Court Could Soon Limit Employees’ Computer Access At Work

On Monday, the United States Supreme Court heard oral arguments in Van Buren v. United States, a criminal case about a federal antihacking law that could have far-reaching implications for workers’ rights.

The case centers around Nathan Van Buren, a former Georgia police sergeant who was convicted of felony computer fraud in violation of the Computer Fraud and Abuse Act (CFAA). Van Buren was accused of extracting a $6,000 payment to run a license plate search to find out whether a strip club dancer was actually an undercover officer.

An Atlanta federal judge ruled in October 2017 that Van Buren violated the CFAA when he accessed the Georgia Crime Information Center for an improper purpose. Two years later, the Eleventh Circuit Court

UConn vs. USC odds, line: 2020 Roman Legends Classic picks, predictions from proven computer model

The USC Trojans and the UConn Huskies meet up in an intriguing non-conference clash on Thursday evening in the 2020 Roman Legends Classic. It is a neutral-site game at the Mohegan Sun in Uncasville, Conn., though the proximity is in favor of Connecticut. USC enters with a 3-0 record that includes a blowout win over BYU in its last outing. UConn is 2-0 on the young season, with wins over Central Connecticut and Hartford in the early going. 

Tip-off is set for 7 p.m. ET. William Hill Sportsbook lists the Huskies as one-point favorites, down half a point from the opening line. The over-under, or total number of points expected, is 142 in the latest UConn vs. USC odds. Before making any USC vs. UConn picks, check out the college basketball predictions from the SportsLine Projection Model.

Youths with autism learn skills to get computer jobs through coding classes | Entertainment/Life

After her son Colby experienced seizures and was diagnosed with a number of health problems, Aisha Williams contacted Families Helping Families NOLA, a resource center for people with disabilities and their families.

The nonprofit operates in Orleans, Plaquemines and St. Bernard parishes, ensuring that people with disabilities are included in school, work and recreational activities, and experience the highest quality of life possible.

With the organization’s help, Williams was able to navigate the next steps of her son’s life. She also landed a job there as a transition specialist. That was nearly 11 years ago. Now, Williams is the executive director and the driving force behind a new program that teaches computer programming to people with autism.

She was once again inspired by Colby, 22, along with her two other sons — Marlin, 17, and Tristan, 13.

“My three boys are all on the autism spectrum. However, they love video

Karis Teetan ‘couldn’t believe’ he was being replaced on smart sprinter Computer Patch | HK Racing

Karis Teetan is no stranger to being tipped off top-line sprinters after strong performances – think Mr Stunning and Hot King Prawn – but even he admits “he couldn’t believe” he was being replaced aboard Computer Patch for next week’s Group One Hong Kong Sprint (1,200m).

Teetan has finished a close second in consecutive outings on the Tony Cruz-trained four-year-old but Computer Patch will instead be ridden by incoming superstar Christophe Soumillon next Sunday.

“I couldn’t believe that I was taken off him, I think I’ve done pretty well on him and last time I thought he got beaten by a better horse on the day,” said Teetan, who defends his crown in the International Jockeys’ Championship at Happy Valley on December 9.

“Anyway, that’s Hong Kong racing, I understand if connections wanted a change and I’ll just move forward. It’s happened to me many times before and I hope

Computer Scam, Business Victimized: Hinsdale Cops

HINSDALE, IL — In the last few days, Hinsdale police have handled cases involving a computer scam, check fraud, underage drinking, a DUI and damage. Here is information from the latest Hinsdale police reports:

  • A resident in the 10 block of North Bruner Street told police Nov. 23 that a pop-up window appeared saying the resident’s computer had been compromised. A suspect gained remote access to the resident’s computer and viewed personal and bank information. The suspect instructed the victim to buy $10,000 in gift cards to resolve the issue. The victim recognized the scam and did not buy the cards.
  • A business check from The Hinsdalean, 7 W. First St., was altered, made payable to a suspect and cashed at a bank in Georgia. The incident was reported Wednesday.
  • William M. McTighe, 30, of Chicago, was arrested at 9:30 p.m. Nov. 25 in the 200 block of East 55th
