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 […]
Kai Sun of the University of Michigan is a humble physics professor with ambitious goals. “I’m mainly a paper-and-pencil type of theorist, doing analytical calculations mostly,” Sun said. “My interests are pretty broad, but basically […]
Insider Brief Engineers at the University of Pennsylvania demonstrated the first integration of quantum networking with commercial fiber-optic infrastructure, transmitting quantum signals using standard Internet Protocol (IP). The team’s silicon-based “Q-chip” coordinated quantum and classical […]
In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) that powers today’s web. Click to rate […]
