Time-frequency analysis provides a framework for examining signals whose frequency content evolves over time. Traditional Fourier analysis decomposes a signal globally into sinusoids and loses ...
In this paper we analyze the Banach *-algebra of time-frequency shifts with absolutely summable coefficients. We prove a noncommutative version of the Wiener lemma. We also construct a faithful ...
Electron spins confined in quantum dots are an attractive system to realize high-fidelity qubits owing to their long coherence time. With the prolonged spin coherence time, however, the control ...
