In each case, the phase being estimated was generated with a phase gate, and each circuit modeled was defined by a randomly selected phase. The model accuracy, prediction speed, overfitting level and variation in accuracy with noise level was determined for 5 machine learning algorithms...

Bases: qiskit.algorithms.phase_estimators.phase_estimator.PhaseEstimator Run the Iterative quantum phase estimation (QPE) algorithm. Given a unitary circuit and a circuit preparing an eigenstate, return the phase of the eigenvalue as a number in [0,1)[0,1) using the iterative phase estimation ...
对应quantum circuit为QFT的Quantum circuit,图源Nielsen&Chuang 然后将qubit反序排列即可得到正常的傅里叶变换。 首先我们考察最后一个qubit,实际上我们可以发现如果 \mathinner{|j_n\rangle}=\mathinner{|0\rangle} ,则其将变换为 \frac{\mathinner{|0\rangle} + \mathinner{|1\...
Here, we implement two suitably modified phase estimation procedures, the Kitaev and the semiclassical Fourier-transform algorithms, using an artificial atom realized with a superconducting transmon circuit. We demonstrate that both algorithms yield a flux sensitivity exceeding the classical shot-noise ...

We introduce a variant of Quantum Amplitude Estimation (QAE), called Iterative QAE (IQAE), which does not rely on Quantum Phase Estimation (QPE) but is only based on Grover’s Algorithm, which reduces the required number of qubits and gates. We provide a rigorous analysis of IQAE and pr...
With on-demand access to a variety of different quantum computers and classical circuit simulators available through Braket, we were able to run the experiments independently, self-paced and with no upfront commitment required. While our demonstration focused on a simplified system with specific entang...
