Abstract Quantum error-mitigation techniques can reduce noise on current quantum hardware without the need for fault-tolerant error correction. For instance, quasiprobability method simulates a noise-free computer using noisy one, with caveat of only producing correct expected values observables. The cost this mitigation technique manifests as sampling overhead which scales exponentially in num...

While Python has become increasingly popular for its convenience, it is also criticized suboptimal performance. To figure out what burdens the interpreter of and provide insights into possible optimizations, we conduct this empirical study on CPython's performance via sampling-based profiling. This approach incurs a low runtime overhead does not require any modification application code, thus p...
