An adolescent girl presented with fever, headache, and mental status changes. Blood cultures 12 hours after admission were positive for Staphylococcus aureus. The initial evaluation did not reveal a source of the patient's sepsis. Forty-eight hours after admission a cardiac ejection click was detected. The chest radiograph showed ill-defined opacities(More)
Recently, there have been significant developments in entanglement-based quantum metrology. However, entanglement is fragile against experimental imperfections, and quantum sensing to beat the standard quantum limit in scaling has not yet been achieved in realistic systems. Here, we show that it is possible to overcome such restrictions so that one can(More)
