An old physical phenomenon, known as the Hall effect, has revealed some new tricks. New findings have potential implications for understanding fundamental physics of quantum materials and developing applied technologies such as quantum communication and […]
Insider Brief ARPA-E announced the QC3 program, which funds quantum computing projects aimed at revolutionizing energy research, such as developing sustainable industrial catalysts and new battery chemistries. The program seeks to overcome the limitations of […]
Multiverse Computing, a leader in quantum AI software, has opened a new office in San Francisco, marking its expansion into the U.S. market. The new branch aims to accelerate the adoption of Multiverse’s quantum and […]
The “species” category is almost certainly the best known of all the taxonomic classifications that biologists use to organize life’s vast diversity. It’s a linchpin of both conservation policy and evolutionary theory, though in practice […]
Quantum Dice, an Oxford University spin-out specializing in quantum random number generator (QRNG) technology, and SCI Semiconductor, a UK-based developer of secure silicon devices, have announced a memorandum of understanding to jointly develop solutions targeting […]
Insider Brief: Skyrmions, stable magnetic structures with topologically protected spin configurations, may be used for creating efficient devices in microelectronics, spintronics, and quantum computing. A study showed that skyrmions can resist noise, maintaining their topological […]
Insider Brief Multiverse Computing is expanding to the U.S. with a new office in San Francisco, aimed at accelerating the adoption of its AI and quantum-based solutions among U.S. businesses and government entities. The San […]
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 […]
