How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple concept behind Bayes’ rule, an approach to calculating probabilities, first proposed in 1763. Now, […]
Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of generating streams of […]
Rice University physicists confirmed that flat electronic bands in kagome superconductors aren’t just theoretical, they actively shape superconductivity and magnetism. This breakthrough could guide the design of next-generation quantum materials and technologies. Click to rate […]
A Vermont research team has cracked a 90-year-old puzzle, creating a quantum version of the damped harmonic oscillator. By reformulating Lamb’s classical model, they showed how atomic vibrations can be fully described while preserving quantum […]
Quantum 9, 1843 (2025). https://doi.org/10.22331/q-2025-08-29-1843 Building upon recent progress in Lindblad engineering for quantum Gibbs state preparation algorithms, we propose a simplified protocol that is shown to be efficient under the eigenstate thermalization hypothesis (ETH). […]
Insider Brief Quantum Research Sciences (QRS), an Indiana-based software company and Purdue Innovates client, has secured a U.S. Air Force contract to develop ACID-R, an artificial intelligence-driven platform that streamlines how the service identifies and […]
Quantum 9, 1842 (2025). https://doi.org/10.22331/q-2025-08-29-1842 Starting with an explicit framework for designing logical Clifford circuits for CSS codes, we construct logical gates for Hypergraph Product Codes. We first derive symplectic matrices for CNOT, CZ, Phase, […]

Quantum 9, 1841 (2025). https://doi.org/10.22331/q-2025-08-29-1841 Variational quantum algorithms are viewed as promising candidates for demonstrating quantum advantage on near-term devices. These approaches typically involve the training of parameterized quantum circuits through a classical optimization loop. […]
Quantum 9, 1840 (2025). https://doi.org/10.22331/q-2025-08-29-1840 Quantum error mitigation is regarded as a possible path to near-term quantum utility. The methods under the quantum error mitigation umbrella term, such as probabilistic error cancellation (PEC), zero-noise extrapolation […]
Suppose a man has already murdered most of your family, including several of your children, for no other reason than that he believes your kind doesn’t deserve to exist on earth. The murderer was never […]
