Title: NIST Develops Bang-Anneal-Bang Quantum Optimization Process
NIST researchers have developed a new quantum optimization process called “bang-anneal-bang.” The process involves several key steps:
1. Identifying the base curve v(t) and setting a total runtime for the process
2. Creating an initial guess for the parameters in the ansatz (quantum circuit)
3. Evolving a quantum state from a ground state B using a Hamiltonian H(t) = u(t)B + (1-u(t))C
4. Measuring the resulting quantum state and updating the ansatz parameters
5. Repeating steps 3-4 until the classical outer loop converges to a selected limit
6. Returning the final form of u(t) to perform the optimized quantum process
The process aims to optimize quantum operations by iteratively refining parameters and converging the quantum state to a desired solution. This could potentially improve the efficiency and accuracy of quantum computing applications.
