The Next Generation Of IBM Quantum Computers
IBM is building accessible, scalable quantum computing by focusing on three pillars:
**· **Increasing qubit counts.
**· **Developing advanced quantum software that can abstract away infrastructure complexity and orchestrate quantum programs.
**· **Growing an ecosystem of quantum-ready enterprises, organizations, and communities.
The next step in IBMâs goals to build a frictionless development experience will be the release of Qiskit Runtime in 2022, which will allow developers to build workflows in the cloud, offering greater flexibility. Bringing a serverless approach to quantum computing will also provide the flexibility to distribute workloads intelligently and efficiently across quantum and classical systems.
To help speed the work of developers, IBM launched Qiskit Runtime primitives earlier this year. The primitives implement common quantum hardware queries used by algorithms to simplify quantum programming. In 2023, IBM plans to expand these primitives, as well as the capability to run on the next generation of parallelized quantum processors.

Silicon Quantum Computing announces worldâs first quantum integrated circuit
After a Sydney-based firm built the worldâs first atomic-scale quantum integrated circuit.
Sydney-based firm Silicon Quantum Computing (SQC) built the first integrated silicon quantum computer circuit manufactured at the atomic scale, in what has been touted as a âmajor breakthroughâ on the road to quantum supremacy, a press statement reveals.
The atomic-scale integrated circuit, which functions as an analog quantum processor, may be SQCâs biggest milestone since it announced in 2012 that it had built the worldâs first single-atom transistor.
A Huge Step Forward in Quantum Computing Was Just Announced: The First-Ever Quantum Circuit
Australian scientists have created the worldâs first-ever quantum computer circuit â one that contains all the essential components found on a classical computer chip but at the quantum scale.
The landmark discovery, published in Nature today, was nine years in the making.
âThis is the most exciting discovery of my career,â senior author and quantum physicist Michelle Simmons, founder of Silicon Quantum Computing and director of the Center of Excellence for Quantum Computation and Communication Technology at UNSW told ScienceAlert.
Theoretical calculations predicted now-confirmed tetraneutron, an exotic state of matter
James Vary has been waiting for nuclear physics experiments to confirm the reality of a âtetraneutronâ that he and his colleagues theorized, predicted and first announced during a presentation in the summer of 2014, followed by a research paper in the fall of 2016.
âWhenever we present a theory, we always have to say weâre waiting for experimental confirmation,â said Vary, an Iowa State University professor of physics and astronomy.
In the case of four neutrons (very, very) briefly bound together in a temporary quantum state or resonance, that day for Vary and an international team of theorists is now here.
Chicago Quantum Exchange takes first steps toward a future that could revolutionize computing and medicine
Flashes of what may become a transformative new technology are coursing through a network of optic fibers under Chicago.
Researchers have created one of the worldâs largest networks for sharing quantum information âa field of science that depends on paradoxes so strange that Albert Einstein didnât believe them.
The network, which connects the University of Chicago with Argonne National Laboratory in Lemont, is a rudimentary version of what scientists hope someday to become the internet of the future. For now, itâs opened up to businesses and researchers to test fundamentals of quantum information sharing.
Using microbrewery waste to synthesize carbon quantum dots
For a few years now, spent grain, the cereal residue from breweries, has been reused in animal feed. This material could also be used in nanotechnology. Professor Federico Roseiâs team at the Institut national de la recherche scientifique (INRS) has shown that microbrewery waste can be used as a carbon source to synthesize quantum dots. The work, done in collaboration with Claudiane Ouellet-Plamondon of the Ăcole de technologie supĂ©rieure (ĂTS), was published in the Royal Society of Chemistryâs journal RSC Advances.
Often considered âartificial atoms,â quantum dots are used in the transmission of light. With a range of interesting physicochemical properties, this type of nanotechnology has been successfully used as a sensor in biomedicine or as LEDs in next generation displays. But there is a drawback. Current quantum dots are produced with heavy and toxic metals like cadmium. Carbon is an interesting alternative, both for its biocompatibility and its accessibility.
Nanostructured surfaces for future quantum computer chips
Quantum computers are one of the key future technologies of the 21st century. Researchers at Paderborn University, working under Professor Thomas Zentgraf and in cooperation with colleagues from the Australian National University and Singapore University of Technology and Design, have developed a new technology for manipulating light that can be used as a basis for future optical quantum computers. The results have now been published in Nature Photonics.
New optical elements for manipulating light will allow for more advanced applications in modern information technology, particularly in quantum computers. However, a major challenge that remains is non-reciprocal light propagation through nanostructured surfaces, where these surfaces have been manipulated at a tiny scale.
Professor Thomas Zentgraf, head of the working group for ultrafast nanophotonics at Paderborn University, explains that âin reciprocal propagation, light can take the same path forward and backward through a structure; however, non-reciprocal propagation is comparable to a one-way street where it can only spread out in one direction.â
