New Algorithm Boosts Quantum Computing with Stable Cat-Qubit Gates
A groundbreaking algorithm, funded by the European Research Council, is transforming quantum computing. This new method optimizes both the shape of control inputs and gate times, starting from an initial seed. It's particularly effective for cat-qubit gates, where Hilbert space dimensions are smaller than the physical Hilbert space.
The algorithm's stability is guaranteed by the stability of both the open-loop adjoint backward system and the forward closed-loop system. It introduces a new monotonic numerical algorithm for generating quantum gates in open systems governed by Lindblad master equations. This method ensures that the optimization process for quantum gate operations in open quantum systems progresses without decreasing performance, typically used in quantum control to achieve reliable gate implementations despite environmental interactions.
The research, significant in the field of quantum computing, optimizes control inputs and gate times for quantum gates, particularly effective for cat-qubit gates. The algorithm's stability ensures reliable gate implementations in open quantum systems, marking a substantial advancement in quantum control.
