Abstract: A quantum computing service may store, in a cache, one or more compiled files of respective quantum functions included in one or more quantum computing programs received one or more customers. When the quantum computing service receives another quantum computing program, from the same or a different customer, the quantum computing service may determine whether the quantum computing program may include one or more of the quantum functions corresponding to the compiled files in the cache. If so, the quantum computing service may use the compiled files in the cache to compile the quantum computing program.

Abstract: A target tracking system and method of operation can include: generating data based on a detection of a shock wave of a bullet by target microphones, the target microphones including an offset target microphone; wirelessly transmitting the data with a target transceiver communicatively connected to the target microphones; determining a bullet speed at the target microphones based on the shock wave detected by the offset target microphone with a processor; and determining a shot placement of the bullet relative to the target microphones with the processor, the processor communicatively connected to the target transceiver.
