In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for instance, can exhibit […]
Quantum researchers have deployed a new algorithm to manage noise in qubits in real time. The method can be applied to a wide range of different qubits, even in large numbers. Click to rate this […]
Insider Brief Glasgow-based M Squared Lasers, once a leading UK photonics and quantum technology firm, has ceased trading and entered administration after nearly 20 years in business. In the UK, “administration” is similar to U.S. […]
Insider Brief Kothar Computing has launched FORGE, a scientific computing platform designed to solve complex quantum many-body problems with high performance and ease of use. The browser-based environment allows quantum researchers to model, simulate, collaborate, […]
Over the last half-billion years, squid, octopuses and their kin have evolved much like a fireworks display, with long, anticipatory pauses interspersed with intense, explosive changes. The many-armed diversity of cephalopods is the result of […]
Quantum 9, 1839 (2025). https://doi.org/10.22331/q-2025-08-28-1839 We prove that $sf{QMA}$ where the verifier may also make a single $non-collapsing$ measurement [7] is equal to $sf{NEXP}$, resolving an open question of Aaronson [5]. We show this is […]
Quantum 9, 1838 (2025). https://doi.org/10.22331/q-2025-08-28-1838 Quantum computers are a highly promising tool for efficiently simulating quantum many-body systems. The preparation of their eigenstates is of particular interest and can be addressed, e.g., by quantum phase […]
An international research team led by Robert Ott and Hannes Pichler has developed a novel architecture for quantum processors that is specifically designed for simulating fermions—particles such as electrons. The method can be implemented using […]
Insider Brief The EU-funded QCDC project established Europe’s first cloud-based trapped-ion quantum computing service, strengthening technological sovereignty and enabling independent research access. Researchers used the platform to run proof-of-concept simulations in biochemical research, computational fluid […]
Quantum computers, systems that perform computations leveraging quantum mechanical effects, could outperform classical computers in some optimization and information processing tasks. As these systems are highly influenced by noise, however, they need to integrate strategies […]
