After recently presenting the most efficient implementation for quantum algorithms, such as the Quantum Fourier Transform, on a linear chain, ParityQC now introduces Parity Twine. The Parity Twine method sets a new world record in optimizing the two crucial metrics of gate count and circuit depth. It outperforms all known state-of-the-art methods for implementing prominent quantum algorithms across a wide range of quantum hardware, including linear, square grids, hexagonal, ladder and all-to-all connected devices.

Now, in a recent study published in Physical Review Letters, Rey and JILA and NIST Fellow James K. Thompson, along with graduate student Sanaa Agarwal and researcher Asier Piñeiro Orioli from the University of Strasbourg, studied atom-light interactions in the case of effective four-level atoms, two ground (or metastable) and two excited levels arranged in specific one-dimensional and two-dimensional crystal lattices.

Quantum physicist Mehul Malik has received a prestigious fellowship in recognition of his outstanding contribution to advancing optics and photonics. Professor Malik has been elected a Fellow Member of Optica (formerly the Optical Society of America), a global society headquartered in Washington, DC, in the United States that promotes the science of light and photonics.

Researchers from the University of British Columbia, the University of Washington, and Johns Hopkins University have identified a new class of quantum states in a custom-engineered graphene structure. Published today in Nature, the study reports the discovery of topological electronic crystals in twisted bilayer–trilayer graphene, a system created by introducing a precise rotational twist between stacked two-dimensional materials.

The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers supported through a quantum research center led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

IonQ Inc., a leader in the quantum computing and networking industries, has signed a Memorandum of Understanding (MOU) with the Busan Metropolitan Government in South Korea - the second largest city in South Korea known as a key technology and economic hub for the southeast region of the country. The agreement highlights a commitment to mutual cooperation in nurturing talent, and advancing quantum technology.

UChicago, Argonne, Tohoku University partnership finds spinel can store quantum information. The gemstone spinel, known for its vibrant colors resembling gems like rubies and sapphires, has now been shown to be capable of storing quantum information, making it a viable material in the field of quantum technology.

In the new network project “Quantenrepeater.Net (QR.N)”, physicists at the University of Stuttgart are researching, developing, and testing special repeaters for the quantum Internet. These repeaters are key to the secure IT infrastructure and communications of the future.

On January 21, the Natural Sciences and Engineering Research Council of Canada (NSERC) announced funding for quantum science projects, including six initiatives at uOttawa. These awards reinforce the University’s commitment to exploring quantum science and driving innovation in Canada.

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team from the University of Innsbruck, together with a team from RWTH Aachen and Forschungszentrum Jülich, has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform all computing operations protected against errors.
