Digitized adiabatic quantum computing with a superconducting circuit
R. Barends, A. Shabani, L. Lamata +26
A major challenge in quantum computing is to solve general problems with limited physical hardware. Here, we implement digitized adiabatic quantum computing, combining the generali…
Artificial quantum thermal bath: Engineering temperature for a many-body quantum system
Alireza Shabani, Hartmut Neven
Temperature determines the relative probability of observing a physical system in an energy state when that system is energetically in equilibrium with its environment. In this pap…
Quantum filter for a non-Markovian single qubit system
Shibei Xue, Matthew R. James, Alireza Shabani +2
In this paper, a quantum filter for estimating the states of a non-Markovian qubit system is presented in an augmented Markovian system framework including both the qubit system of…
Quantum filter for a class of non-Markovian quantum systems
Shibei Xue, Matthew R. James, Alireza Shabani +2
In this paper we present a Markovian representation approach to constructing quantum filters for a class of non-Markovian quantum systems disturbed by Lorenztian noise. An ancillar…
Computational Role of Multiqubit Tunneling in a Quantum Annealer
Sergio Boixo, Vadim N. Smelyanskiy, Alireza Shabani +7
Quantum tunneling, a phenomenon in which a quantum state traverses energy barriers above the energy of the state itself, has been hypothesized as an advantageous physical resource…
Exploring Transfer Function Nonlinearity in Echo State Networks
Alireza Goudarzi, Alireza Shabani, Darko Stefanovic
Supralinear and sublinear pre-synaptic and dendritic integration is considered to be responsible for nonlinear computation power of biological neurons, emphasizing the role of nonl…
