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.
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’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.
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.
As a company built and maintained on a deep foundation of technology, Amazon.com(NASDAQ:AMZN) is always looking to hone its competitive edge. Its latest attempt in this regard is, apparently, the development of proprietary quantum computing.
According to a report from Bloomberg published on Tuesday, internal job postings the media company had gained access to and information on LinkedIn strongly suggest that Amazon aims to build a quantum computer. The company is seeking to hire experts for a quantum hardware team, which will be housed inside its Amazon Web Services Center, said the report.

Additionally, the LinkedIn page of a current company employee named Marc Runyan describes him as “Quantum Research Scientist at the Amazon Center for Quantum Computing.”
Today’s standard computers store information in binary form as either 0s or 1s, in units called bits. Quantum computers instead are based on so-called qubits, which can be
With Q.COMPUTE and Q.NETWORK, Aliro Quantum is using cloud tech to make it easy for software developers to run quantum programs and networking engineers to build quantum networks.
If you’re a developer who wants to write code for a quantum computer, how do you know which quantum architecture and by extension which company’s
is best suited for the problem you’re trying to solve? Likewise, if you’re interested in connecting quantum computers together across a quantum network, how do you pick the right hardware and network design?
Aliro Quantum, thinks the answer to both these questions is to use an abstraction layer.
On this episode of
, I talk with Dr. Prineha Narang, Assistant Professor at the John A. Paulson School of Engineering and Applied Sciences at Harvard University and CTO and co-founder Aliro Quantum about how the company is trying to make quantum more accessible with
Nov. 16, 2020 — VTT and IQM have entered into an agreement to establish a co-innovation partnership and begin building Finland’s first quantum computer.
The cooperation will bring together top expertise in quantum technologies and enable a leap in Finland’s quantum capabilities. The government of Finland has granted the project EUR 20.7 million funding.
The computer will be built in Espoo, Finland at VTT’s and Aalto University’s joint national research infrastructure Micronova, where the clean room environment used to manufacture the quantum components is located. Work will begin already during 2020.
“Finland has the potential to be the European leader in quantum technologies. I look forward to witnessing the opportunities that quantum will present to Finnish and European businesses and the competitiveness of the entire region,” states Finland’s Minister of Economic Affairs, Mika Lintilä.
The project proceeds in three phases

Five quantum computing companies, three universities and one national physical laboratory in the UK have come together in a £10 million ($13 million) new project, with an ambitious goal: to spend the next three years trying to make quantum technologies work for businesses.
Called Discovery, the program is partly funded by the UK government and has been pitched as the largest industry-led quantum computing project in the country to date. The participating organizations will dedicate themselves to making quantum technologies that are commercially viable, marking a shift from academic research to implementations that are relevant to, and scalable for businesses.
The Discovery program will focus on photonic quantum computing, which is based on the manipulation of particles of light – a branch of the field that has shown great promise but is still facing large technological barriers.
On the other hand, major players like IBM and Google are both developing
