I am a physicist specializing in quantum information and quantum computation, and currently a staff research scientist at IBM Quantum.
Recent highlighted work:
- Diagonalization of large many-body Hamiltonians on a quantum processor: experimental demonstration of the real-time quantum Krylov algorithm applied to simulation of the ground state energy of 2D Heisenberg models on up to 56 qubits.
- Quantum Krylov Algorithm for Szegö Quadrature: .
- Observation of Improved Accuracy over Classical Sparse Ground-State Solvers using a Quantum Computer: applying the sample-based quantum Krylov diagonalization algorithm to a synthetic Hamiltonian on 49 qubits and showing that it reaches higher accuracy than classical SCI.
