Pennsylvanians looking to Sen. Bob Casey for that moral clarity are not finding it. His past positions are troubling, especially considering what has happened in Israel.

Texas A&M has fired football coach Jimbo Fischer, bringing his six-year tenure with the Aggies to a close while netting himself $76 million.

Americans have had enough of the bigotry and intolerance of DEI.

The NCAA granted University of Miami tight end Cam McCormick a waiver Thursday to play in his ninth consecutive season of college football.

Kit Harington is set to star in Empire of Dirt (w/t), a ‘British Western’ set in the Lake District

All3Media-backed New Pictures and Kit Harington and Daniel West’s Thriker Films have partnered to produce eight-part thriller Empire Of Dirt (working title).

That's a serious question for Jewish Democrats who care about Israel. In my 40 years in politics, I've watched plenty of disagreements between U.S. presidents and Israeli prime ministers. But I have never seen the most senior figures in the Democratic Party come together to treat Israel as badly as they are doing today.

Tiger Woods' Jupiter Links Golf Club will be adding Max Homa, Tom Kim, and Kevin Kistner to its roster as it prepares for the upcoming TGL season.

Pulled by a locomotive powered by misogyny, hate and retribution, this train will shortly leave democracy station, bound for fascism junction.

Spin-spin exchange interactions between semiconductor spin qubits allow for fast single- and two-qubit gates. During exchange, coupling of the qubits to a surrounding phonon bath may cause errors in the resulting gate. Here, the fidelities of exchange operations with semiconductor double quantum dot spin qubits in a Si-SiGe heterostructure coupled to a finite-temperature phonon bath are considered. By employing a master-equation approach, the isolated effect of each spin-phonon coupling term may be resolved, as well as leakage errors of encoded qubit operations. As the temperature is increased, a crossover is observed from where the primary source of error is due to a phonon-induced perturbation of the two-electron spin states, to one where the phonon-induced coupling to an excited orbital state becomes the dominant error. Additionally, it is shown that a simple tradeoff in pulse shape and length can improve robustness to spin-phonon-induced errors during gate operations by up to an order of magnitude. Our results suggest that for elevated temperatures within, exchange gate operations are not currently limited by bulk phonons. This is consistent with recent experiments.
