Nonlinear Landau-Zener-Stückelberg-Majorana problem
Sahel Ashhab, Olga A. Ilinskaya, Sergey N. Shevchenko
In the standard Landau-Zener-Stückelberg-Majorana (LZSM) problem, the bias sweep rate and gap are both time independent and fully characterize the LZSM problem. We consider the non…
Quantum state preparation protocol for encoding classical data into the amplitudes of a quantum information processing register's wave function
Sahel Ashhab
We present a protocol for encoding real numbers stored in memory registers into the amplitudes of the quantum superposition that describes the state of qubits. Th…
Superradiance phase transition in the presence of parameter fluctuations
S. Ashhab, K. Semba
We theoretically analyze the effect of parameter fluctuations on the superradiance phase transition in a setup where a large number of superconducting qubits are coupled to a singl…
Selective darkening of degenerate transitions for implementing quantum controlled-NOT gates
P. C. de Groot, S. Ashhab, A. Lupascu +4
We present a theoretical analysis of the selective darkening method for implementing quantum controlled-NOT (CNOT) gates. This method, which we recently proposed and demonstrated,…
Inverse Landau-Zener-Stuckelberg problem for qubit-resonator systems
S. N. Shevchenko, S. Ashhab, Franco Nori
We consider theoretically a superconducting qubit - nanomechanical resonator (NR) system, which was realized by LaHaye et al. [Nature 459, 960 (2009)]. First, we study the problem…
Quantum algorithm for obtaining the energy spectrum of a physical system
Hefeng Wang, S. Ashhab, Franco Nori
We present a polynomial-time quantum algorithm for obtaining the energy spectrum of a physical system, i.e. the differences between the eigenvalues of the system's Hamiltonian, pro…
