Quantum 8, 1510 (2024). https://doi.org/10.22331/q-2024-10-24-1510 We present an explicit quantum circuit that prepares an arbitrary $U(1)$-eigenstate on a quantum computer, including the exact eigenstates of the spin-$1/2 XXZ$ quantum spin chain with either open or […]
Quantum 8, 1509 (2024). https://doi.org/10.22331/q-2024-10-24-1509 We investigate the limitations of quantum computers for solving nonlinear dynamical systems. In particular, we tighten the worst-case bounds of the quantum Carleman linearisation (QCL) algorithm [Liu et al., PNAS […]
Insider Brief In this analysis, we look at recent headlines on China’s progress in quantum technologies and the limitations of comparing leadership positions of nations in the pursuit of developing and commercializing those technologies, including […]
Insider Brief WISeKey has signed Convertible Notes Subscription Agreements for up to $30 million via private placements with institutional investors, starting with an initial issuance of $2.5 million. The convertible notes have a maturity of […]
Insider Brief The upcoming SpaceX CRS-31 mission, set for early November 2024, will carry the SEAQUE quantum communication experiment to the International Space Station (ISS). A University of Illinois at Urbana-Champaign-led project, SEAQUE will test […]
Figure. QEYSSat: A quantum receiver in space. Credit: Canadian Space Agency by Amara Graps It’s a simple idea. XOR, ⊕, is a bitwise operator, that means “exclusive or.” The logical operation it performs, is: if the […]
Insider Brief: The European Union is expanding its quantum communication capabilities through the EuroQCI initiative to establish ultra-secure communication channels across its member states. The latest funding call encourages consortia to propose solutions involving both […]
For the first time since the discovery of the material MnBi2Te4 (MBT), researchers at the University of Twente have successfully made it behave like a superconductor. This marks an important step in understanding MBT and […]
An international research team has pioneered a new technique to identify and characterize atomic-scale defects in hexagonal boron nitride (hBN), a two-dimensional (2D) material often dubbed ‘white graphene’ for its remarkable properties. This advance could […]
Insider Brief At Quantum World Congress 2024, Microsoft’s VP of Quantum Software, Dr. Krysta Svore, highlighted the integration of quantum computing with AI and high-performance computing (HPC) to drive scientific breakthroughs, emphasizing the partnership with […]
