In 360 BCE, Plato envisioned the cosmos as an arrangement of five geometric shapes: flat-sided solids called polyhedra. These immediately became important objects of mathematical study. So it might be surprising that, millennia later, mysteries […]
Researchers from The University of Tokyo and IBM have demonstrated Krylov Quantum Diagonalization (KQD) on an IBM Heron quantum processor, successfully simulating the Heisenberg model on a 2D heavy-hex lattice of up to 56 sites. […]
Quantum Dice, a University of Oxford spin-out specializing in quantum random number generator (QRNG) technology, and Astute Group, a global electronics distributor and supply chain partner, have announced a strategic global distribution partnership. As part […]
Qunnect, a company deploying quantum entanglement-based protocols over commercial fiber, has closed an oversubscribed Series A extended financing round, securing $10 million. The round was led by Airbus Ventures, with additional participation from Cisco Investments […]
Global Data Quantum, a Spanish company, has added its Quantum Portfolio Optimizer software to IBM’s Qiskit Functions Catalog. This new application function was introduced at the IBM Quantum Partner Forum 2025 in London, enabling finance […]
Landauer’s principle is a thermodynamics concept also relevant in information theory, which states that erasing one bit of information from an information system results in the dissipation of at least a specific amount (i.e., kBTln2) […]
Q-CTRL, a provider of quantum infrastructure software, has announced the availability of its Fire Opal performance management software on Rigetti’s latest 84-qubit Ankaa-3 quantum computer, accessible via the Rigetti Quantum Cloud Services (QCS) platform. This […]
Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a pair—validating a key principle of physics at the […]
Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using magnetic fields. These currents are vital for spintronics, a faster and more energy-efficient alternative to electronics. […]
Quantum 9, 1783 (2025). https://doi.org/10.22331/q-2025-06-24-1783 In this study, we explore the information capacity of open quantum systems, focusing on the effective channels formed by the subsystem of random quantum circuits and quantum Hamiltonian evolution. By […]
