What are conditional reset operations in IBM Quantum?
These conditional reset operations therefore represent one of IBM Quantum’s first forays into dynamic quantum circuits, alongside our recent results demonstrating an implementation of an iterative phase estimation algorithm.
How is quantum phase estimation ( QPE ) Circuit limited?
The Quantum Phase Estimation (QPE) circuit that we have learned and used previously is limited by the number of qubits necessary for the algorithm’s precision.
How is IBM working to bring quantum computing to developers?
IBM Quantum is working to bring the full power of quantum computing into developers’ hands in the next two years via the introduction of dynamic circuits, as highlighted in our recently released Quantum Developer Roadmap.
How to build circuit with non-unitary operations?
1. Understand a circuit with non-unitary operations. Before we learn how the IPE algorithm works, lets review reset and conditional operations in Qiskit that go into building a IPE circuit. Read the Qiskit tutorial here ( go to Non-unitary operations section ) to understand how to build a circuit that performs conditional operations and reset.
How to find the average sequence fidelity in Qiskit?
Average over the Km K m random realizations of the sequence to find the averaged sequence fidelity, is the average sequence operation. Repeat Steps 1 through 4 for different values of m m and fit the results for the averaged sequence fidelity to the model:
How to measure and reset a qubit in the middle of a circuit execution?
Chief among these is the ability to measure and reset a qubit in the middle of a circuit execution, which we have now enabled across the fleet of IBM Quantum systems available via the IBM Cloud. Measurement is at the very heart of quantum computing.
How to calculate the average fidelity of RB?
(where n = nQ n = n Q is the number of qubits). As an example, we calculate the average sequence fidelity for each of the RB sequences, fit the results to the exponential curve, and compute the parameters α α and EPC. 3. The Intuition Behind RB
