Aer is a high performance simulator for quantum circuits that includes noise models
### Summary In #1242 we added a basic smoke test job for MPI builds using standalone mode. That job builds aer in standalone mode with MPI and then runs a...
### Summary Adds basic profiling code to find suitable threshold values for OpenMP and gate fusion for backend options. This is a revised version of #956. ### Details and comments...
### Summary This PR addresses issue #789. It adds the instruction `initialize_ket` to `Circuit` which acts like the standard `initialize` instruction except that the target statevector is specified using dictionary...
### Summary Optimization of Sampling in QubitVector ### Details and comments In original implementation, a loop for sampling is iterated based on sample count. In this optimized implementation, a loop...
### What is the expected behavior? With the recent changes to the gate fusion algorithm and including SIMD we should re-evaluate the default threshold values for enabling OpenMP, and for...
### What is the expected behavior? `sample_measure` returns `s` measurement results, where `s` denotes the number of shots. Current implementation take `O(s * 2^n)` run time. #819 improves it to...
### What is the expected behavior? For expectation value with `variance=True`, the simulator should perform measurements instead of direct calculation of the expectation value. And calculate the variance of course....
### What is the expected behavior? Allow a user to add a list of quantum noise errors (depolarizing, thermal...) to all qubits with one function call. ### Proposed solution: In...
### What is the expected behavior? Currently in Aer, an AerJob with a particular ID is created on every execution. This mimics the IBMQJob and its async execution model. However...
### Summary This PR fixes typos. ### Details and comments `random_statevector` returns `qiskit.quantum_info.Statevector`. So, an `AerStatevector` instance must be created as the next process. Also, the documentation has been modified...
