Suppressing qubit dephasing using real-time Hamiltonian estimation
Suppressing qubit dephasing using real-time Hamiltonian estimation is a scholarly work by Shannon P Harvey, John M Nichol, Stephen D. Bartlett, and Andrew C Doherty, published in 2014 in ''Nature Communications''. The main subjects of the publication include quantum, quantum technology, quantum mechanics, quantum information science, qubit, Hamiltonian, physics, quantum computing, open quantum system, decoherence-free subspace, quantum decoherence, quantum error correction, quantum information, Dynamical decoupling, Coherence time, computer science, spin exchange relaxation-free magnetometer, Coherence, Dephasing, and quantum sensor. The authors continuously adjust qubit control parameters based on this information, thereby improving the inhomogenously broadened coherence time "Equation missing" from tens of nanoseconds to >2 μs.
