Intel together with QuTech (a venture that is a collaboration between the Netherlands Organization for Applied Scientific Research and the Delft University of Technology) – recently have published some important advancements into solving the interconnect bottleneck issue. This is an important advancement because this issue exists between quantum chips that sit in cryogenic dilution refrigerators and the complex room-temperature electronics that control the qubits. These advancements technology were covered in many industry-leading science journals like Nature, and mark a big milestone in solving one of the biggest challenges to quantum scalability, all achieved with Intel’s new cryogenic controller chip named Horse Ridge.
A quantum physicist team affiliated with the Max Planck–New York City Center for Nonequilibrium Quantum Phenomena recently developed a novel platform capable of controlling light at a nanoscale wavelength. They manipulated the light by programming a layered crystal’s electromagnetic response. Other than controlling nanolight itself, this discovery can potentially lead to new quantum information processing and imaging capabilities.
Scientists from Aalto published a paper detailing the results when they used an IBM quantum computer to explore a rarely-studied area of physics by challenging ideas about information around 100 years old at the quantum level. The paper is titled ‘Quantum simulation of parity–time symmetry breaking with a superconducting quantum processor’.
UK Research and Innovation (UKRI) is sponsoring 7 projects with £31 million to solve some of the unexplored mysteries in fundamental physics. Here are the projects:
In the right conditions, scientists can fast-forward or rewind a quantum computer’s evolution just like a VHS tape or cassette. An article published by a team of theoretical physicists from the Austrian Academy of Sciences describes the process.
In December 2020, Bálint Koczor, Robert Zeier, and Steffen J. Glaser published their academic paper called Fast computation of spherical phase-space functions of quantum many-body states. The paper introduces new and faster ways to calculate these functions.
A team of researchers at CEA-Leti in France and the University of Copenhagen’s Niels Bohr Institute have made 2D arrays on a 300mm CMOS wafer to boost quantum computers.
THE British based company, Quantopticon, was founded by a number of physicists who have been developing their software suite over the past two decades. Quantillion was developed with the purpose to help researchers and designers build smarter photonics devices. As the competition for building quantum computers and Qubits heats up, scientists are looking at ways to build more effective photonic devices, faster and more cost effectively. This is where the rapid prototyping software can replace physical prototyping in the design cycle.
As of late November 2020, The University of Science and Technology of China (USTC) has announced its new breakthrough. Through collaboration with Heidelberg University in Germany and The University of Trento in Italy, they have successfully created a new 71 site Bose–Hubbard quantum simulator. This is groundbreaking for electrodynamics, especially gauge theory.
Aaron Young is a researcher at the University of Colorado in the Kaufman group where he looks “under the hood” of quantum physics aiming to understand how nature can be exploited to build technological innovation the Quantum Computing space.
