  • Publication number: 20240086756
    Abstract: An information processing apparatus determines a combination of a first data qubit and a second data qubit that further reduces the energy represented by an energy equation. The energy equation includes first to third energy terms. The first energy term is used to identify the first data qubit on which a Z error has occurred. The second energy term is used to identify the second data qubit on which an X error has occurred. The third energy term reduces the energy as the number of data qubits each being a third data qubit on which both a Z error and an X error have simultaneously occurred increases. The information processing apparatus determines that a Y error has occurred on the third data qubit.

  • Publication number: 20240065992
    Abstract: An aortic aneurysm has few noticeable symptoms and is at high risk of rupture without a sign of abnormality. Further, if the aortic aneurysm ruptures, it causes a shock state due to massive blood loss and results in a very low survival rate. Thus, when the aortic aneurysm is found by physical examination or the like, surgery with a stent graft or the like needs to be performed according to the state of its progression. A pharmaceutical composition for preventing and treating an aortic aneurysm including a medium chain fatty acid as a main component has an effect of inhibiting the occurrence and progression of the aortic aneurysm. Thus, when the aortic aneurysm is found, continuous intake of the composition can not only inhibit the progression of the aortic aneurysm but also mediate the regression of the aortic aneurysm, thereby producing the effect of improving vital prognosis.
